We don't use LVM snapshots for VM disks. oVirt snapshots are using
qcow2 logical volumes per
VM snapshots.
Hi,
This is valuable information. I didn't read it anywhere so far.
We'll have to evaluate what impact this way of snapshoting has on
performances.
Thanks a lot.
Allow me one last question before I stop spamming you...
Using virt-v2v for migration from Oracle VM ("raw" files) to KVM, it
seems that the "preallocated" option for (iSCSI) LVM volumes is
mandatory.
We may have to change some currently large volumes to
thin-provisionning.
What would be the fastest way to do that ? (maybe directly, not in a
two phases migrations)
Again, thanks a lot.
