@CodeMercenary Just a guess, but is there any NFS lock perhaps involved because of the CPU getting pegged and there being a timeout of sorts? Check the lockd daemon state, perhaps.

RE: GPU support and Nvidia Grid vGPU
@msupport Many thanks for your write-up! Have you experienced any issues communicating with the NVIDIA license server?

RE: GPU support and Nvidia Grid vGPU
@msupport Please write up all the steps involved, as this would be very useful documentation for anyone else wanting to accomplish this. Many have delayed switching to XCP-ng because of not being able to make use of NVIDIA GPUs.

RE: Feedback in regards to upcoming XO update
@john-c The plugin I wrote send all data available to XO, and XO is doing the parsing and display.
As we only work currently with the Mona model, we are not concerned by liquid cooling and other things like this.
To have some history, I recommend using the Netdata plugin and plug it into a Prometheus to have long-term data. For now, XO is displaying real-time value directly from the BMC, with no history.
If you have some values you think are nice to have (in fact, the PSU status was not my idea, but feedback from my community), don't hesitate to tell us !
It's still a work in progress, nothing is set in stone -
RE: CPU Provisioning
@Kajetan321 You should consider the effects of NUMA/vNUMA in terms of performance. Crossing over to other physical CPUs or memory banks will create slowdowns.
If possible, unless you absolutely need all those VCPUs on any or both VMs, you may be best off splitting the 36 VCPUs and assigning 18 on each VM, checking to see if all the memory stays with the bank(s) of those specific VCPUs. See my articles on the CUCG site about NUMA and in particular, graphics performance (and of course, calculations will also be affected). Best would be to
run benchmarks with both configurations. Shrinking the number of VCPUs on a running VM can lead to issues (as indicated in the video posted just before my response).
