Common useful commands for KVM Guests
LVM error fixes:
- not exclusive for KVM, but since I have so many of these VM's thats where I see it a lot.
- commonly happens when do-release-upgrade is run, or when some updates happen to the lvm code. My GUESS is that the metadata contains the lvm version in there somewhere and does not get updated.
- This fix is only for the metadata
WARNING: PV /dev/sda5 in VG dns01-vg is using an old PV header, modify the VG to update.
Fix:
