Hi!
I have created a guest disk like this:
a) lvcreate -L 30G -n Vm1 VolGroup
b) mkfs.xfs /dev/VolGroup/Vm1
And installed the VM like this:
c) virt-install --name=vm1.mydomain.com \
--disk path=/dev/VolGroup/Vm1 \
… rest_of_arguments
Questions:
1) Is b) above necessary, or are a) and c) sufficient?
2) If b) is necessary, should /dev/VolGroup/Vm1 be mounted while installing and
while running the VM?
If you're passing OS install media to virt-install, the b) is not required: the os installer will format the disk, same as it would on a physical machine.
Thanks!
1) So no mounting on host then?
No, shouldn't be required.
2) Is it possible to take a LVM snapshot of the guest from the host (and make a backup)?
Yes, but you'll want to make sure the guest is shutoff and not writing to the
LV. I'm not too familiar with LVM snapshots though
