Package: qemu-system-x86
Version: 1.7.0+dfsg-9
Severity: grave
Justification: renders package unusable
Dear Maintainer,
Since kernel 3.13 migrated into jessie, I cannot start KVM guests
anymore.
If I boot on the last jessie 3.12 kernel (3.12.9-1), I can start the
guests with no problem.
I hoped some newer kernel and qemu would fix it and waited both
have a new version in jessie which is now the case; unfortunately the
result is the same: after starting the guest with a command-line such
as:
kvm -net nic,model=virtio -net tap,script=no,downscript=no,ifname=tap0 -drive
file=/var/local/kvm/taz-test.img,if=virtio -usbdevice tablet -k fr -vnc
localhost:2 -daemonize -name taz-test
The cpu goes 100% for a while and then the kernel is spouting messages
on all terminals.
This is what I get in syslog:

I cannot tell if this is a kernel or qemu bug but since this behaviour
shows up when I run qemu I file this bug against it. Feel free to
reassign as needed.
Thanks in advance for any solution.
