Subject: [fedora-virt] Fedora reboots when using libvirt
Sent: Mon, Dec 2, 2013 6:28:51 PM

Hi

This is my system:
Fedora 19
libvirtd (libvirt) 1.0.5.7
( I downgraded to this kernel version trying to solve the problem, but no luck.)

-------------

This is the error message:

[ 536.083922] Disabling lock debugging due to kernel taint

I was running a virtual machine using qemu-kvm.

What i already tried:

- memtest -> no error.

- formatted and installed only the base system (no DE).

- downgraded kernel: 3.9.5-301.fc19.x86

- swapped the disk with another server (no error with kernel 3.9.5 but i could only test during some hours, i dont have an extra machine anymore)

Any suggestions?

Thanks, and sorry my not-good english
