(I deleted the other errors caused by trying to load drivers that don't
exits).

I reboot 3 systems mirantis_[457]

/var/log/libxl/* kicks out.
mirantis_4.log:libxl: error:
libxl_dm.c:1311:libxl__destroy_device_model: Device Model already exited
mirantis_5.log:libxl: error:
libxl_dm.c:1311:libxl__destroy_device_model: Device Model already exited

These are more interesting.

I wonder if libxl has a race condition.


I'm completely unaware of libxl works, so I can only guess.  But this
looks like an error in libxl.  Maybe someone else has an idea?

If I reboot a single vm through libvirt/libxl the system reboots
normally.
If I have several vm's reboot at the same time then The systems go into
a paused state and do not reboot.
I then have to kill them via xl and   restart them.


Do logs [1] uncover something?
