@dthenot Great! I'm happy I was able to help test it. I look forward to the update release.
Interesting note, CR is faster when the snapshots are not deleted.... or CR is faster because of the update, I'll test again after the fix.
Can you retry with an up-to-date xcp-ng 8.3 please?
FYI on recent XCP-ng 8.3 versions the pci-passthrough will enable the ROM expansion bar. The guest VM will have access to it, so no need to pass it via qemu anymore.
See my comment on GitHub: https://github.com/xcp-ng/xcp/issues/786#issuecomment-4281846490

Think i might revert back to VHD as this has cause so many issues.
Different use cases: Ceph is better with more hosts (at least 6 or 7 minimum) while XOSTOR is better between 3 to 7/8.
We might have better Ceph support in the future for large clusters.
