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

[Edoardo Comar]

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.
