[libvirt-users] Using a shared LVM volume group for both virtual disks and host filesystems

Hi
I have a test environment where a single LVM volume group is used
both as a storage pool for virtual machines' disks AND for the LVs used
for the HOST system filesystem.
I never use libvirt commands to start/stop/activate the pool. Only to
create/delete volumes.
The test environment works fine.
How suitable would be a shared VG for a production environment ?
thanks,
Edoardo Comar
PS -
This discussion seems to imply that separate VGs give more safety against
data corruption in case of bugs ... did not point to real cases of
failure.
