I just installed CentOS 5.1 for dom0 and tried to install 32bit centos 5.1 on my 64bit dom0.
but this is still doesn't work, i think
my machine is dell pe1950 which is support both vmx and pae.
here is what i do exactly,
first, install centos 5.1 to brand new machine for dom0.
[root@vmp-1 ~]# uname -a
2.6.18-53.el5xen #1 SMP Mon Nov 12 02:46:57 EST 2007 x86_64 x86_64 x86_64 GNU/Linux
and i create xen pv guest using i386 boot kernel for centos 5.1
now, it seems ok, everything going well
but while installing package, it prints out kernel panic message and give me dom0's shell prompt.
my BIOS is newest, so i don't think it is BIOS problum for me.
any idea for this?

Thank you for responding. I actually just got it working after a BIOS

a BIOS problem that was causing the complete freezing, though Xen was
still performing unreliably until we upgraded to
I'm glad to hear that Centos 5.1 is out now, though, as it will be a lot
easier to upgrade than to support our own xen rpms for now. I'll check
it out. It would actually be interesting to see if the new version works
with the original BIOS as well.
