hypervisor - ubuntu natty 2.6.38-13-server #57-Ubuntu SMP Mon Mar 5
19:52:44 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
a VM, also ubuntu based, was hanging on vm initiated reboot, without
any useful error messages.
virsh destroyed the domain, killed -9 the remaining process and can
not start up the vm now.
hangs at "Booting from Hard Disk" message.
the fs is active-active-drbd/ocfs2, in sync and clean, other VMs are
running in on the same fs.
tried copying the image to local disk and another system and had the
same issue starting up the vm.
libvirt debug 1 output doesn't show anything useful.
qemu-img doesn't seem to support any checking of raw disk format,
which is what we use as the default in all vms.
