The performance is certainly attractive from the minimal testing I've done with it (almost 5x I/O performance increase).  For my environment I'm hitting the snapshot bug on replica 3 setups so I cannot snapshot VMs and doing so breaks the VM.  This is a deal breaker for me since the VM backup software I'm using relies on snapshots.  The other of course is the lack of HA, that I could probably work around.  Is there actually a timeline when libgfapi is expected to be working properly?  Some of the bug reports I've seen date back to 2017.

I use libgfap in production, the performance is worth a couple of quirks for me.

- watch major version updates, they’ll silently turn it off because the engine starts using a new version variable
- VM/qemu security quirk that resets ownership when the VM quits, was supposedly fixed in 4.3.6 but I still have it happen to me, a cron’d chown keeps it under control for me
- some VMs cause a libvirt/vdsmd interaction that results in failed stats query, and the engine thinks my VMs are offline because the stats gathering is stuck. hoped a bug fix in 4.3.6 would take care of this too, but didn’t. may be my VMs though, still analyzing for specific file issues

I need to spend some time doing a little more research and filing/updating some bug reports, but it’s been a busy end of year so far…

Are there currently any known issues with using libgfapi in the latest stable version of ovirt in hci deployments?  I have recently enabled it and have noticed a significant (over 4x) increase in io performance on my vms. I’m concerned however since it does not seem to be an ovirt default setting.  Is libgfapi considered safe and stable to use in ovirt 4.3 hci?
