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. http://serverfault.com/questions/200728/lvm-volume-group-shared-between-k...
