RE: XenServer VM Tools 9.3.3 from Citrix causes bluescreen
Is there a way to get past the inaccessible boot device message once a 2022 server has hit that without a complete new server reinstall?

RE: Remove backup bottleneck: please report
Thank you so much for this info, I can't believe I didn't see this in all of my research. With the information from that document I take it back. I am getting full bandwidth since 12 machines get backed up at a time. The individual VM transfer speed in the backup reports was a bit misleading to me since I didn't realize that 12 are uploaded to storage at a time.
My initial finding still stands though, going http completely removed the one bottleneck that we had in our backup infrastructure and made it 3.5 times faster then before.

RE: Remove backup bottleneck: please report
I will for sure attempt and see how fast it is to backup only one VM at a time... actually I guess I don't know the answer to this but when XO does a delta backup to an NFS remote does it attempt to transfer all VM snapshots at the same time or does it do it sequentially one after the other?

RE: Remove backup bottleneck: please report
For me, switching to http seems to have increased the backup speed by about 3.5 times as well. However I feel like it's still pretty slow. I went from a reported transfer speed average of 3.26 MiB/s to 11.59 MiB/s across 16 VMs running on a pool consisting of two 8.1 XCP-ng hypervisors and a 5.61 Xen Orchestra Community VM backing up to an NFS share on a Synology RackStation over a 10 Gb/s storage network. When testing the speed with which I am able to write to the NFS share from the XO VM with dd it's averaging write speeds of about 95 MB/s.
Anything else I can do to try and figure out where the next bottleneck is?
