Package: libvirt
Version: 0.7.2-4
Severity: important
Hi,
I just upgraded my system. After a reboot (of the host), my virtual machines
(debian lenny) does not boot any more.
When I try to start my virtual machine (virsh start --console guestname),
I show the grub screen, the start of the boot and it freeze when trying to
remount the root fs.
I booted with init=/bin/sh, run manually the scripts in /etc/rcS.d, run
/etc/rcS.d/S10checkroot.sh with tracing (bash -x /etc/rcS.d/S10checkroot.sh
start)
and see that the freeze occurs during the remount of the root fs.
On the (serial) console, I can see a kernel message such as (I did not write
it when I saw it):
====
task mount:102 blocked for more than 120 seconds.
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
====
I do not see in 0.7.2-4 changelog what would explain this compared to 0.7.2-3.
But the fact is that I tried to reboot with several kernel, I tried to use
qemu-kvm,
kvm from unstable, kvm from testing and I always have this freeze.
Then I downgraded libvirt0, libvirt-bin, python-libvirt from 0.7.2-4 to 0.7.2-3
and virtinst from 0.500.0-3 to 0.500.0-2 and than my guest has been booting
correctly as always (and here again, it is working with several kernels, with
kvm and the new qemu-kvm).
So this bug seems clearly related with the libvirt package.
I set the severity to important because the 0.7.2-4 package is a no go for
me. But I do not see other bug report, so I'm not sure if this problem is
widespread. If this is the case, the severity should be dumped to block testing
migration.
Regards,
Vincent
