I am new to Xen, has 14 years of Linux experience so I have no problem tackling difficult topics, but dont want to waste time unnecessarily.

If you want the fastest path to getting Xen running with guests.. then what you probably want is XCP: http://xen.org/products/cloudxen.html http://wiki.xen.org/xenwiki/XCP_Overview http://wiki.xen.org/xenwiki/XCP_Introduction It''s basically a bootable/installable CD linux dom0 based on centos with a xen distribution built-in that''s manageable from citrix xencenter (compatible as XCP is derived from citrix xenserver).

Yes I spent a two days before coming here trying to get a feel for what is necessary. The web resources are sketchy and pretty inconsequential. If you search the web, you will find most new to Xen is looking for a distro with Dom0, so that they can concentrate on figuring out the rest. It immediately resonated with me as the logical step. I just echoed that sentiment. The response by Nick Kamis and Sehr Geehrter Herr Dettenbach, is an unnecessarily uncouth slap through the face no one deserves. I strongly suggest those who are tired dealing with new users create a new usergroup for advanced users and you all go there, and let (new to Xen) users have a Xen group they can help each other at their level. The name Xen-users group is deceiving based on the level of support you are willing to give newcombers. We all have to start somewhere and most of you forgot that. Except for the two constructive responses I received from Aaron and Andrew, the group serves no purpose for someone new to Xen. You cannot have it both ways attacking new users who ADMIT in the first line of their posts to be new to Xen and then expect that new users will take up Xen. I honestly don''t understand what you want to achieve other than to alienate new users from Xen. If the two people who succeeded to troll with me did not pull their triggers, there would have been three posts total period.. wouldn''t that be nice? See where we are now... count the mails.

(I would be very surprised if it doesnt exist)Last time I looked, OpenSuse did a very good job of integrating Xen. I''ve never been a fan of RPM based distros, and I''m not sure of where OpenSuse stands vis-a-vis the current Xen release, but if you really want to just install and move on to configuring DomUs - that might be a place to start. Personally, I do most of my work on Debian, and my production servers are still running Lenny and Xen 3 - so my experience is dated (and about to get refreshed): - the basic install is easy: simply an apt-get of the current package - there''s a bit of trickiness in getting all the various configuration stuff right - in lots of places (from kernel parameters in Grub and on - and I expect this has changed again, what with grub changes going from Lenny to Squeeze) - there are things to worry about like memory ballooning, pinning VCPUs, time sources, etc. -- make sure to read through http://wiki.debian.org/Xen For what it''s worth, I''ve found Xen more capable than all the other virtualization alternatives - at least for my purposes - but I''ve also found the open source version to be rather touchy, and it takes a lot of time and attention to get everything wired together reliably (more so, if you''re building any kind of high-availability cluster).

Ever moved out of the cultural armchair and watched Spike Milligan or Faulty Towers or ...? Us Germans do it to ourselves most of the time...and they (e.g. Cleese & Milligan) know it as they pile on the humor. I learnt the problem very quickly when I started to work in the US. We are quick to be experts but never wrong and like to beat up on smaller guys or someone who is perceived to know less. It is the sad old behavior that just plays out over and over. I know the Britts learned this the hard way by taking the brunt of the expertise. Yes it will be my last post to you..unless an "expert" hijacks this thread again and throw a V-2 from high altitude.

I started with xen on centos. But moved to xcp the free xenserver6 (mostly for xencenter) I think you will find xcp/xenserver to be the more fully featured system but you will pretty much choke on the documentation, but its there. The documentation provided by citrix for xenserver works for the most part for xcp. Protip: the commands in xenserver ( and xcp afaik ) tab complete which helps with the learning curve.

OP can complain all he wants, i work 80 hour weeks at my day job, I''m on call 24/7/365, and I run a midlevel hosting company on the side. I''ve managed to setup an enterprise xen HA cluster and launch VPS services to my customers from the grass up in a little less than a month. I assure you, the information is out there but this technology is still very raw and fast moving so you have to work for your knowledge.

IMHO, the original poster asked what struck me as three eminently reasonable questions: - what''s "the shortest path to install a Xen Dom0 and then Xen guest images?" and more specifically - for a pointer to "a Xen enabled distribution that would enable me to immediately start configuring DomU guests," - and a pointer to "good step by step introduction or tutorial on how to install the Guests in bridged and Nat mode respectively" Given the complexity of Xen, and the paucity of good documentation, these seem perfectly reasonable questions. The first two responses were direct, and rather obnoxious attacks. A couple of us suggested looking at OpenSuse (still the only distro I know of that makes an explicit point of integrating Xen rather than treating it as an add-on). Someone else suggested "The book of XEN" as a good reference. Given that there are now about 7 Xen books out, of varying age, but all costly - that''s a useful piece of information as well. (By the way - any opinions on the best current HowTo for Xen on Debian - specifically Xen 4.1 and/or XCP on Squeeze; with bonus points for a high-availability configuration?)

The very first search result is http://wiki.debian.org/Xen, which is - a short path - a pointer to a distribution - a step-by-step instruction Obviously, the OP never cared to do even as little as a slightest google search. Well, naturally this could make people feel somewhat... emm, annoyed? And as of his next posts - the things just became worse. If a stranger comes to your home, demands to go clean his toilet and threatens to go away if you don''t - wouldn''t you answer "so go away, fine"? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Xen is fairly easy to set up, and I think if you stick to simple stuff then it''s little more than "apt-get install xen-hypervisor-<something> xen-tools-<something>". "apt-cache search xen-hypervisor" will show you the package versions available. The main niggle (as already hinted at) is that Grub2 defaults to putting Xen boot options after native kernels. The easy fix for that is to change the name of the files in (IIRC) /etc/grub so that the Xen config file comes before the native kernels (Linux) config file. Initially, avoid trying to get PyGrub working. Just copy the DomU kernel and initrd to Dom0 and boot from those. PyGrub does mostly work, but it can be a bit fiddly getting the right version of Grub that will run in a DomU - the version in Stable (Squeeze) bombs out as it can''t understand the disk setup. admin@mmri.us wrote:>>Im very suspected to your mental hypersensibility > >Gee Sigmund, ...

Simon... thanks for the info. Sounds like things are a little easier since my last round of Xen3/Lenny installs. Have the various nits re. pinning CPUs (to avoid weird crashes) and having to set up clock jiffies gone away - or is there a new round of nits that have to be picked?

I don''t understand why there are 36 replies full of hatred on a thread that is somehow "irrelevant" to the XEN community, while there are threads that are not even minimally considered out there. I consider people that spends time subscribing to a mailing list (hence reading it) to be part of a whole community that is supposed to support people having issues. As I said, there are threads in which people is ranting about the inability of making their XEN installation to work. This people need our time, need our brain, our intuitions and our knowledge. Please, don''t waste your time (and readers'' time) by writing injuries or complaints that lead to nowhere at all. I''m nobody so, please, don''t say I have not the right to tell people what to do because this is totally not my intention. Mine''s just a suggestion coming from a XEN enthusiast that doesn''t want his mailbox to be filled with 36 (mostly useless) messages in less than 8 hours.

Hi, It''s sad to see this thread got into such a state, while some may feel the OP should have just "RTFM" it''s just not that easy to find the very babysteps of working with Xen right now. That aside, I have been working on correcting this issue - I have just been horribly pressed for time. My startup just got funded this week and I am in the process of acquiring another company, so I sympathize with everyone here that is also working 100+ hours a week and still finding time to contribute to Xen. We love our community, we love our technology but we need to be open to bringing in new members in and not unnecessarily be hostile even when they should have "RTFM". So getting to buisiness. I recommend getting started with Debian Squeeze running Xen 4.0.1 this is painless, stable and VERY well supported way of getting a Xen setup in < 1hr. Because of this I have started documenting the process here ready for inclusion in the wiki when I can find the time to complete it: https://docs.google.com/a/orionvm.com.au/document/d/1q9odKP8Id26J8kHCAFt8aD5krXdUiZnZGw1Q-LGWCJg/edit?hl=en_US This guide covers basic Xen concepts along with a functional install, PV guests and Windows HVM example setup. Please don''t hesitate to contact me with any questions regarding the above and any help/contributions would be greatly appreciated. Also I will heavily +1 Gentoo. Gentoo 3.1.0-r1 kernel released recently and Xen 4.1.2 form my current development environment, my desktop also runs on this stack. Simply unmask the new gentoo-sources, xen and xen-tools then emerge -av gentoo-sources xen xen-tools Then make sure the gentoo-sources kernel is selected with eselect, finally build your kernel in /usr/src/linux - making sure to select Xen support, ethernet bridging and the usual stuff. Setup grub to use xen.gz and your kernel and you are good to go. Kind regards, Joseph. On 10 November 2011 20:00, Niels Dettenbach <nd@syndicat.com> wrote:> Am Donnerstag, 10.

Sadly My IBM 336 servers I want to try it on does not seem to have virtualization in Bios as your document requires. I will see if there is maybe a Bios update that will add it. But, what kind of performance hit is expected if I run it without bios support for VT ? I therefore have to use para-virtualization. Your document seems to suggest (but do not mention) that PV would be fine for unmodified Linux guest but that any other operating system needs be modified. Is that correct?

Yep that is 100% correct. I was operating on the assumption most people would have access to VT/AMD-V enabled hardware these days.

Not shure how far VirtualBox is there today.

Roeleveld:> My main issue with the documentation is that I have not been able to find > out which kernel-options are really needed for XenThis differs a bit between Dom0 and Domu and mainly between the "old" 2.6.38 and the "new" (3.x - pvops) kernel. At least you have to enable all required XEN flags / drivers for backend or frontend. If it helps you i can post a example kernel config fpr 2.6.38 (SuSe backport - sys-kernel/xen-sources in portage) i used properly (but you have to add your hardware drivers by your own). On 3.2 i''m still fiddeling here... ;) On 2.6.38 i use the same kernel for Dom0 and DomU for testing purposes (preferred to compile in most instead of building as modules). The kernel does not build if i enable CONFIG_XEN_BLKDEV_TAP2 It could be wise to build the CONFIG_BLK_DEV_LOOP as module which allows you to change the number of loopback devices later / on running sys. --- snip --- # XEN CONFIG_XEN_PRIVILEGED_GUEST=y CONFIG_XEN_PRIVCMD=y CONFIG_XEN_DOMCTL=y CONFIG_XEN_XENBUS_DEV=y CONFIG_XEN_NETDEV_ACCEL_SFC_UTIL=m CONFIG_XEN_BACKEND=y CONFIG_XEN_BLKDEV_BACKEND=y CONFIG_XEN_BLKDEV_TAP=y # CONFIG_XEN_BLKDEV_TAP2 is not set CONFIG_XEN_NETDEV_BACKEND=y CONFIG_XEN_NETDEV_TX_SHIFT=8 # CONFIG_XEN_NETDEV_PIPELINED_TRANSMITTER is not set CONFIG_XEN_NETDEV_LOOPBACK=m CONFIG_XEN_PCIDEV_BACKEND=y CONFIG_XEN_PCIDEV_BACKEND_VPCI=y # CONFIG_XEN_PCIDEV_BACKEND_PASS is not set # CONFIG_XEN_PCIDEV_BACKEND_SLOT is not set # CONFIG_XEN_PCIDEV_BE_DEBUG is not set CONFIG_XEN_TPMDEV_BACKEND=m CONFIG_XEN_SCSI_BACKEND=y CONFIG_XEN_USB_BACKEND=m CONFIG_XEN_BLKDEV_FRONTEND=y CONFIG_XEN_NETDEV_FRONTEND=y CONFIG_XEN_NETDEV_ACCEL_SFC_FRONTEND=m CONFIG_XEN_SCSI_FRONTEND=y CONFIG_XEN_USB_FRONTEND=y # CONFIG_XEN_USB_FRONTEND_HCD_STATS is not set # CONFIG_XEN_USB_FRONTEND_HCD_PM is not set CONFIG_XEN_GRANT_DEV=y CONFIG_XEN_DISABLE_SERIAL=y CONFIG_XEN_SYSFS=y CONFIG_XEN_NR_GUEST_DEVICES=256 CONFIG_XEN_COMPAT_030002_AND_LATER=y # CONFIG_XEN_COMPAT_030004_AND_LATER is not set # CONFIG_XEN_COMPAT_030100_AND_LATER is not set # CONFIG_XEN_COMPAT_030200_AND_LATER is not set # CONFIG_XEN_COMPAT_030300_AND_LATER is not set # CONFIG_XEN_COMPAT_030400_AND_LATER is not set # CONFIG_XEN_COMPAT_040000_AND_LATER is not set # CONFIG_XEN_COMPAT_040100_AND_LATER is not set # CONFIG_XEN_COMPAT_LATEST_ONLY is not set CONFIG_XEN_COMPAT=0x030002 CONFIG_XEN_SMPBOOT=y CONFIG_XEN_DEVMEM=y CONFIG_XEN_BALLOON=y CONFIG_XEN_SCRUB_PAGES=y CONFIG_XEN_DEV_EVTCHN=y --- snap --- you may "split" that into two kernels as described in the official Gentoo Xen howto.> and how "xl" works as > it''s not a true drop-in-replacement for "xm".This is true.

On 3.2 i''m still fiddeling here... ;)Always useful. The options you listed below should be sufficient. I''d prefer to move to kernel 3.2 though.

What I found seemed to indicate that xl doesn''t use xend and will work without xend running. But when using xm, xend is needed. -- Joost _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Guess I''ve got some reading/googling > to do.This is not completely clear to me and i would not put my hand in any fire for it... I assume it relys to any kind of buffer / mapping within the network stuff. In openSuSe (just read that) these value seems changed to 10, others use 12 here - i just left the default for now as initially recommended by the regarding xen code / patch writer. I still have some strange TCP / networking problems with some older DomUs after upgrading to 4.1.2 (from 3.4.3) - this may or may not related to this setting.> > CONFIG_XEN_PCIDEV_BACKEND=y > > CONFIG_XEN_PCIDEV_BACKEND_VPCI=y > > Only when passing PCI-devices to domUs, right? :)Yes, but did not worked with it yet (lack of time)...> > CONFIG_XEN_TPMDEV_BACKEND=m > > CONFIG_XEN_SCSI_BACKEND=y > > CONFIG_XEN_USB_BACKEND=m > > These three, only when passing the devices to the domU?Yes...> > CONFIG_XEN_NETDEV_ACCEL_SFC_FRONTEND=m > > Need to read up on this, name sounds interesting....afair that only affects special network accel hardware (Solarflare NICs).> > Yes (in Dom0). > > Ok, the documentation I found was contradictory on this point. > What I found seemed to indicate that xl doesn''t use xend and will work > without xend running. > But when using xm, xend is needed.Ok, right, my fault... this is new to me (work with 4.x just since some days now...). As i just have some own older scriptwork relying on xm i need this at least until i''ve ported them... If you work just with the new xl toolchain you did not require xend any longer...Thanks for pointing me here... cheers, Niels. -- --- Niels Dettenbach Syndicat IT&Internet http://www.syndicat.com/ _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
