Dear team,
My name is Luwen Zhang from Vinchin Backup & Recovery.
I'm sending you this Email because our developers encountered some
problems while developing incremental backup feature following the oVirt
documentations.
https://www.ovirt.org/documentation/incremental-backup-guide/incremental-...
We downloaded oVirt 4.4.1 from oVirt website, and is now developing based
on this version, as per the documentation when we perform the first time
full backup, we should obtain a "checkpoint id", so when we perform
incremental backup using this ID we should know what's have changed on the
VM. But now the problem is that we cannot get the checkpoint ID.
The components and versions of oVirt are as follows:
You are using qemu 4.2 and libvirt 6.0. These versions are too old, missing
some features or have bugs which will not be fixed. These version maya be
good enough for development, but your product will need newer version.
We require now libvirt 6.6 and qemu 5.1. These versions will be available
in CentOS 8.3.
On libvirt, incremental backup will be fully supported only in RHEL AV
8.3.1. I guess we will build the relevant version for CentOS after this
version is released for RHEL.

Could you please kindly check on this issue and point out what should be
wrong and what we should do?
Looking forward to your reply.
Thanks & regards!
