Description Eyal Edri 2012-12-27 10:14:51 UTC
Description of problem:


Version-Release number of selected component (if applicable):
L0 host: 3.6.10-2.fc17.x86_64 #1 SMP Tue Dec 11 18:07:34 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

qemu-* versions:

qemu-kvm-tools-1.0.1-2.fc17.x86_64
qemu-img-1.0.1-2.fc17.x86_64
qemu-common-1.0.1-2.fc17.x86_64
qemu-system-x86-1.0.1-2.fc17.x86_64
qemu-kvm-1.0.1-2.fc17.x86_64


How reproducible:


Steps to Reproduce:
1.install f17 L0 host with vdsm-nested-hook 
2.create L1 nested hypervisor running rhel63 on it
3.add L1 nested host to an ovirt/rhevm setup as host. 
  
Actual results:
qemu crash on l0 host, and nested l1 host is in bootloop/pause mode

Expected results:
nested l1 host is running and booting OK.

Comment 3 Ohad Basan 2013-01-23 09:12:55 UTC
Tried switching the host to fedora18. experiencing a kernel panic upon boot after turning on nested kvm in the kernel.

Comment 4 Cole Robinson 2013-04-01 19:38:32 UTC
F17 + F18 have the 3.8 kernel nowdays, can someone retest and see if the issue persists?

Comment 5 Ohad Basan 2013-04-02 08:17:53 UTC
I don't see a qemu crash anymore.
but I do encounter a different problem

Thanks Ohad, closing this as CURRENTRELEASE then, we can track the kernel issue in your other bug.
