| Hi Boris,
I definitely don't want to start a flame on this topic and I ran the gitco rpms w/o fail.
I am just personally conservative is all.
Its great of gitco to make available the latest Xen stuff for Centos/RHEL and I do use them in certain situations. On Feb 11, 2009, at 11:37 AM, Boris Derzhavets wrote:

One last thing, I'm pretty conservative and my network designs always work so I suggest keeping with the version of Xen shipping with your distro.
I run Centos 5.2 which ships with Xen 3.2 or something like that *************************************************************** CentOS 5.2 ships with Xen 3.1.2 Hypervisor, kernel is still 3.0.3 Looks like you want http://gitco.de to go out of business , but they are pretty much in ;) *************************************************************** which runs smoothly w/o fail.
I would only go outside the box if requiring a feature not found in your shipped sw or running into a documented bug which is addressed in a later version.
Of course, required features depend on your system design which depend on your business requirements but thats just my suggestion to you.

I am compiling Xen from source on FC9. On booting the
Xen dom0 kernel it gives the following error:
Volume group "VolGroup00" not found
and ultimately the error that switchroot: mount failed: No such file or directory
So my question is that why it fails to detect logical volumes?
Something along this should fix your problem:
# depmod 2.6.18.8-xen
# mkinitrd -v -f --with=dm-mod --with=dm-mirror --with=dm-snapshot --with=dm-zero /boot/initrd-2.6.18.8-xen.img 2.6.18.8-xen
you may also need to load specify some sata drivers for your system.
If that doesn't work, then do an 'lsmod' on your system(non-xen kernel) and add any driver listed there that seems related to storage(scsi, sata, ata, etc..) to the initrd as well.
I did that. But a few of the drivers (e.g. ata_general) are absent in Xen based kernel so mkinitrd fails to include it (this driver is otherwise present in my FC9 system). So now the question is how do I include this ata_general in xen kernel?
Thanks,
Abdul Qadeer
