Finding the best OS for a Xen Dom0
Submitted by specialj on Fri, 2008-08-01 21:13.
I’ve been using Xen for a while now but I’ve not found an OS I’ve really been happy with for running a Dom0. I tried Ubuntu for a while, and while it’s Xen support is fine it’s not such a great server OS at this time (like bug 120375). Debian 4.0 (Etch) does not have blktap support in its kernels. Debian 5.0 (Lenny) will not ship with a dom0 kernel. I suspect Centos 5.2 might be my next attempt. I may also investigate non-GNU/Linux systems though I’ve not heard particularly good things about then Xen support.

dom0 support in Debian Lenny
you can install the 2.6.18 kernel from Debian Etch onto Debian Lenny and that appears to work OK in my testing so far. dom0 ability will be available in Debian Lenny (for kernels greater than 2.6.18) as soon as upstream (the kernel developers) finishes up the "paravirt-ops" stuff.
there is no distro that i know of that supports dom0 booting on a kernel greater than 2.6.18 without serious forward-porting of patches which is messy.
