Re: [Fedora-xen] Fedora 10 on RHEL5.3 x86_64

[Mathieu Chouquet-Stringer]

Hello Mike,

I've been browsing the web for I've been having the same issue you
describe in the email attached below...  Have you made any progress?

I've been able to install F10 on RHEL 5.3 but only has an HVM.  Now I'm
trying to switch it to paravirt and no luck.  It just doesn't even start
booting.  Creating an empty shell and telling it to use F10 initrd and
kernel yields the same result.

I should get more time to investigate this week but I was wondering if
you figured it out?

Best,

I just installed 32bit Fedora 10 Xen domU guest on CentOS 5.3 dom0. It seems to
work just fine..

I had to create a kickstart file that forces installation of kernel-PAE instead of 
normal non-PAE kernel, because only PAE kernels are supported for 32bit Xen PV domUs.

It's known Fedora 10 anaconda installer bug: https://bugzilla.redhat.com/show_bug.cgi?id=470905

64bit Fedora 10 Xen domU shouldn't have this bug/problem.

My F10 Xen domU kickstart installation file is here:

Yeah, I read about that.  In my case it was an issue with NX...  The F10
kernel was trying to use it though it was disabled on the host (dom0)
causing 'invalid instruction' errors.
I enabled it in the BIOS and it worked.  That said it's still a bug but
I found a fix mainstream (or even in bugzilla, don't remember).
