Hi Everyone, How does one install Ubuntu 10.04 DomU in PV mode when running Xen 4.0? My Dom0 is also running 10.04. Can I still use the CD? Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Everyone, In my HVM guest''s config file, I have given my guest 3 interface. I have called them fw1, fw2 and fw3. I have joined each interface to a bridge on the Dom0. This does appear when I do a "brctl show". However, there are 3 other interfaces also added called tapx.0,tapx.1 and tapx.2 (Where x is the domain ID for the guest). Furthermore, I am only able to run

Hi Everyone, I upgraded my CentOS 5.5 to Xen 3.4.2 using this guide: http://www.syntaxtechnology.com/2010/01/upgrade-xen-3-0-on-centos-5-4-x86_64-to-xen-3-4-2/ Now, using the new kernel that it gave me, the system doesn''t seem to be able to detect vt-x.. In virt-manager, Local Install Media and Network Boot are greyed out.. Any ideas? Thanks

Hi Everyone, To convert an HVM install to PV, is it just as simple as creating a new config file, and use the "kernel" and "initrd" parameters to boot from a XEN kernel stored in the Dom0, and use the (ex) HVM''s disk image in the "disk" parameter? Or is there something else I am missing? Thanks _______________________________________________ Xen-users

Dear *, I''m more used to work with RedHat like OSes. Still, I did not denied the request from a user who wants a domU based on ubunto. I usually use virt-install to do the job, with a script similar to this one: #!/bin/sh BASE=SL-4.7-i386-pv \ virt-install --nographics \ --nonsparse \ --paravirt \ --noreboot \

Hi Everyone, In order to prevent DomU from entering promiscuous mode, is it just a matter of adding these 2 rules when the vif is created? # Accept packets leaving the bridge going to the domU only if # the destination IP for that packet matches an authorized IPv4 # address for that domU. iptables -A FORWARD -m physdev --physdev-out vif1.0 \ --destination 216.146.46.43 -j ACCEPT

Hi Everyone, In the guest image I download from stacklet, a Ubuntu 10.04 x86_64 DomU, in /var/log/auth.log, I see: /dev/hvc0: No such file or directory listed a lot of times. I''m not experiencing any problems, however it makes looking through logs for auditing purposes a bit annoying. Any ideas what this is? I think it has something to do with the "Hypervisor Console",

My future plan currently looks like this for my VPS hosting solution, so any feedback would be appreciated: Each Node: Dell R210 Intel X3430 Quad Core 8GB RAM Intel PT 1Gbps Server Dual Port NIC using linux "bonding" Small pair of HDDs for OS (Probably in RAID1) Each node will run about 10 - 15 customer guests Storage Server: Some Intel Quad Core Chip 2GB RAM (Maybe more?)

Hi Everyone, I have a Xen host (Xen 3.4.2) which is running CentOS 5.5 Dom0. I wish to install Dell OpenManage to get a nice web interface with hardware status. Do I need to do anything special to get this working on a Xen host? Or does it work out of the box? The reason why I''m asking, instead of trying, is that my server is currently on its way to a colo, and I won''t have

Hi Everyone, Does anybody have any experience using pfSense on Xen? I would most probably have to use HVM... My idea would be to use PCI-Passthrough to the pfsense DomU, and only make the Dom0 accessable via the pfsense firewall Thanks Jonathan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Everyone, I am going to get a storage server which will be connected to my Xen hosts via iSCSI/Ethernet. I wish to use LVM for the DomU disks. The storage server will have a RAID10 array, and 2 Xen hosts will connect to this (Each will have a 50% share of the RAID10 array, space wise). What is the best way to go about this? Should I: a) Split the RAID10 array into 2 partition on the

Hi Everyone, This is going to sound silly but... I''m just off the phone with a Microsoft SPLA reseller. They sell licenses to run Microsoft software in a hosted environment. I was asking about obtaining Windows licenses to run on my Xen VPS hosting solution. Maybe there is a big misunderstanding, but I''m faily sure she said that it was illegial for me to rent out Xen

Hello, we are using 3.4.3 from Gitco.de on 64bit Centos 5.8 and we have PV guests 64bit. According to described security bug we are in danger. What do you suggest? Wait for gitco update or build xen own with patch? Br Peter

Hi Everyone, When you want to use ionice to limit the amount of disk a DomU has, due to have to run ionice on every blkback process? Incidently, what is the format of the blkback process? I see the following in ps aux: blkback.xx.xvda blkback.xx.xvda1 blkback.xx.xvd where xx appears to be the domain ID. I''m curious as to the last few letters mean? Thanks

If a DomU was compramised, could the Dom0 or other DomUs be compramised? I guess I''m trying to work out how much isolated Xen gives.. Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Folks, How scalable is dovecot. Do you think a machine with a dual core 2.8Ghz processor and 2GB of RAM would do a business with 600 users? This server will have a 100Mbps link to the net, however it will be access by the business using a couple of ADSL lines (Roughly 7Mbps each). This machine will also be running Postfix Your help is appreciated Cheers Jonny

Hi, When I login to a Ubuntu 10.04 virtual machine instance running in Xen through SSH, the console''s lines are clipped at the middle section of my 15.6" screen. I''ll be glad if somebody can suggest a fix. This is turning out to be very annoying.

Hi Everyone, How can I make use of xm sched-credit in a VPS hosting environment? Can I use "xm sched-credit -d <domain>" in a script at system startup, or does this have to be run after the respective guest has been started? Also, what happens when the guest is shutdown then restarted, or rebooted? Do I need to run that command again? If so, how would I automate this process?

Hi Everyone, I have a Dell R210 server which has a Xeon X3430 Quad Core CPU (2.4Ghz x 4) with 8GB of RAM. I intend to use the H200 controller in a RAID1 setup How many VMs do you think I''d be able to run on this machine? Is 20 pushing it? I''d say most (if not all) guests would be in PV mode.

Hi there, I am currently evaluating OpenSolaris as a replacement for my linux installations. I installed it as a xen domU, so there is a remote chance, that my observations are caused by xen. First, my understanding of "zpool [i]scrub[/i]" is "Ok, go ahead, and rewrite [b]each block of each device[/b] of the zpool". Whereas "[i]resilvering[/i]" means "Make
