Hello, I am running a functional Xen 4.0 platform. The objective is the project I am currently running is to replace 4 VMWare ESX by 4 Xen 4.0 hypervisors. I have been able to reproduce all the core VMWare features in Xen (but better of course =D) except memory overcommitment. I know this feature has been included since Xen 3.3 but I have found almost no information about it. When I try to

Understanding that a samba 4.x ADDC should be run on a an os separate than a samba 4. file server, I was thinking of virtualizing both. Is it common to have a single physcial server with two VM's running samba? If some is there a recommendation on how much hardware to start with and how much virtual hardware to give each VM. I'm wondering about virtual nics and if there may be a

Hello Andrey, I am testing a small AD DC setup with 65 users and would like to know if you've had stable experience with running DC and File Server on one server. My test server is Dell Poweredge 2950 with SAS hard drives and 16 GB RAM. So far everything runs normally with no high load and similar I/O on samba ports compared to the old standalone Samba 3 server I will be replacing. Thank

Hi guys, First of all, sorry for my poor english. This is my first message at this list. I''m using Xen on several machines since last November. Right now I''m having a specific problems with 2 servers: both are losing the network on dom0 but all guest systems are still running fine. Looking at those dom0 logs I''ve discovered that sometimes linux kernel OOM-Killer

Does anyone, is anyone running Xen on NFSv3 successfully? What are some of your pain points/success points? Have you tried a clustered file system with better results such as DRBD or GFS?

Nah, RHEL 5.1+ supports 32-bit domU (PAE and non PAE) on 64-bit dom0. Actually RHEL Xen is 3.1 with the brain damaged 3.0 userland utilities. -Ross ----- Original Message ----- From: centos-bounces at centos.org <centos-bounces at centos.org> To: CentOS mailing list <centos at centos.org> Sent: Fri Feb 29 04:46:42 2008 Subject: Re: [CentOS] error creating Centos 5.1 x32 dum_U

I was able to solve the problem with the following configuration: label custom1 MENU custom1 kernel pxechain.com append ::custom1/pxelinux.0 label custom2 MENU custom2 kernel pxechain.com append ::custom2/pxelinux.0 configdir1/pxelinux.cfg/default configdir2/pxelinux.cfg/default Then I dropped the custom pxelinux.0 files in their respective directories, confgdir1 and configdir2.

I accidentally realized today that any domU''s using the paravirt disk driver potentially suffer from poor performance when they get handed in a physical volume and partitioning is done inside the guest. The physical volume passed in has to be one that has the compat 512 logical sector size but hints its real sector size (eg. 4096) as physical sector size. In dom0 handling is correct and

This is an issue I've researched quite a bit on bug lists, and looked in the Syslinux Wiki for a way to do this, but haven't yet found a solution. 1) I have an existing Fedora 13 LiveCD which I burned to a CD and tested on a system without issue. 2) I then took that same ISO and dropped it in my pxelinux.cfg/default for being able to boot over the network. I made sure to extract the

Hello, I get a VM crash while trying to load a database. The "smaller" tables are loading OK, but When I try a bigger one (#3 000 000 rows) the ASCII dump file is #766 MB. When I try to load that table the machine crash and I find always the same message in the "qemu....log'' file : xc_map_foreign_batch: mmap failed: Cannot allocate memory xc_map_foreign_bulk error 12 I

While researching another issue unrelated to Syslinux, I found some mildly disturbing news that affects Syslinux. As HPA stated back on 2009-06-04, hard drive manufacturers are pushing towards a 4096B (4kiB; 4k) native sector size. They're calling it "Advanced Format Technology". It appears that WD (Western Digital; WDC) is the first with some products being released back in

I am testing some kickstarts on ESXi virtual machine with pair of 16GB disks. Partitioning is lvm over raid. If i am using "logvol --grow i get "ValueError: not enough free space in volume group" Only workaround i can find is to add --maxsize=XXX where XXX is at least 640MB less than available. (10 extents or 320Mb per created logical volume) Following snippet is failing with

Using the 2.0.6 demo cd image, I booted the supplied freebsd image and rsync''d the file system to an NFS server.

Hi All, For quite some time I've used raid 1 as a means of providing a rollback mechanism for an upgrade (which I learned from others long ago). So essentially, before an upgrade you split the mirrors and upgrade one side or the other. If your upgrade goes well you sync one way, if your upgrade does not you sync the other (much hand waving and chanting going on, as its more complicated than
