Red Hat Bugzilla – Bug 1013641
RHEL-5.9 loops in early boot stages, taking all CPU

Description of problem:
This is F20 x86_64 constantly updated since Alpha-RC1.
It's the first time I tried to run my old RHEL-5.9 image (was working in F19) on F20 so I can't tell whether it's been caused with some update or it's like this since the initial install.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Try to install (or run already installed image) RHEL-5.9 x86_64
The guest machine loops in early boot stages, taking 100% CPU.
Does rmmod kvm_intel && modprobe kvm_intel emulate_invalid_guest=0 make any difference? If so, please dup this to 1012119
That does not seem to make any difference.
Can you provide the guest XML (sudo virsh dumpxml $vmname) and /var/log/libvirt/qemu/$vmname.log

virsh dumpxml $vmname
Jiri, if you 'sudo virsh edit $vmname' and change <domain type> to qemu, does the guest boot? (albeit very slowly)
Yes, with <domain type='qemu'> it boots (very slowly).
Jiri, can you provide /proc/cpuinfo?
Also, please try kernel 3.12 from rawhide, on the host machine.
Gleb, Paolo, ideas for further debugging?

3.12.0-0.rc7.git2.1.fc21.x86_64 makes no change
There's a kernel bug tracking similar issues:
The 3.13 kernels in rawhide have the referenced patch. Jan, can you give the latest rawhide kernel a spin as well?
If that kernel fixes the boot issues, we can dup this to the kernel bug.
3.13.0-0.rc0.git5.1.fc21.x86_64 doesn't seem to fix it.
Okay, to summarize:
- RHEL5.9 guest
- Started fine on F19, seems to loop endlessly on f20
- 3.13 kernel from rawhide doesn't help
- Running without KVM _does_ make things work
- Host cpuinfo and guest commandline are in previous comments
Paolo, Gleb, any ideas what else to debug here?
Jiri, even with a newer kernel it will take a few minutes to boot.
Yes, with <domain type='qemu'> the boot takes many minutes.
With <domain type='kvm'> it stucks on https://bugzilla.redhat.com/attachment.cgi?id=805216 even with rawhide's 3.12 and 3.13.
FWIW that graphical corruption should be fixed by latest spice-gtk queued for F20, but it shouldn't affect this issue.
With <domain type='kvm'> it will be stuck for several minutes and then proceed at normal speed.

I don't see that red patterns anymore.

I left it running for 15 minutes, but no progress.

And a moment after I posted the previous comment it started to boot :-D
at what seems to be normal speed.
And after updating guest from RHEL-5.9 to RHEL-5.10 (kernel-2.6.18-371) everything's OK even with host's 3.11.9-300.fc20
