I'm pretty sure the crash is DRBD related: until the secondary drbd
server is detached, all is working well. There are 23 guests running,
right now, some of them paravirtualized, other full virtualized. Some of
them use files images, other logical volumes (all of them over a drbd
device).
And I don't have a resource starvation, but a kernel crash and an
immediate reboot.
