2.6.35.2, .4 and 36-rc3: gpf from proc/libvirtd when starting guest

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have a guest that I can start that causes 2.6.35.2, 2.6.35.4 and
2.6.36-rc3 to lock up. I've only been able to get a full crash out
of .2 though. I can start other guests without problems, it seems
and the major difference between them and this one is that the one
that causes the crash runs asterisk. This crash happens on a cleanly
rebooted system and occurs even if the crash-causing guest is the only
one started.

The box is a dual core intel with 4gb of ram and .config for the kernel
is attached.

qemu-kvm 0.12.5 is in use with libvirtd 0.8.3. Guests are started as a
non-root user.

Not sure what other info to provide so please shout.
