Thanks...

I tried at first the driver from above:
NVIDIA-GRID-CitrixHypervisor-8.2-550.54.10-550.54.14-551.61
what doesn’t work.
After this I have found the newer Version:
NVIDIA-GRID-CitrixHypervisor-8.2-550.54.16-550.54.15-551.78
Now the Error on VM startup does not came up and the driver installation in the VM works.

The Driver packages what are specially for Xenserver8 are not installable on the Xcp-NG Version 8.2.1 because the different Base "https://xcp-ng.org/forum/post/80461https://xcp-ng.org/forum/post/80461"

now I get one VM working with a vGPU but a second one does not detect the mapped vGPU and the windows driver cant be installed
I am currently not sure why this happens, because a copy of the working one with another vGPU config will work.
The Xentools and Windowsversions are the same and the template also

the vGPU rpm is installable without any problems

I am currently trying to get a NVIDIA Telsa M10 working with the latest updated Xcp-ng 8.2.1 Build Date 2024-07-17.

The Drivers "NVIDIA-vGPU-xenserver-8-550.54.10.x86_64.rpm" are installed and the system was rebooted. Now it is possible to select a vGPU via XOA for the VM.

Further the extracted vgpu file from the CitrixHypervisor-8.2.0-install-cd.iso was copied to /usr/lib64/xen/bin/vgpu and is executable.

The Start of the VM exited with:

"FAILED_TO_START_EMULATOR(OpaqueRef:0cc388f0-b606-469d-b68c-b4713c7f4abb, vgpu, Daemon exited unexpectedly)
"

Is there someone who has solved this Problem?

Platform:
HPE DL380 Gen10

Thanks for the Feedback @ all

I have tested some commands from above and discovered something

the columns with the wait timings are much higher than the from the fast host
that’s very strange from my point of view.

further the CPU stat does not shows correct values because the fast host was at the time of the command under heavy load with about 80%.

on the slow was some load but there the CPU is much stronger

@bleader: the comand "get-cpufreq-average" gives no output at all.

@Affonso thanks for this...

doese the cpu boost the frequency on load or is the cpu permanetly on 2,7ghz

that is correct, but there are no errors in the storage system. the raid is built with two Raid 10 arrays SAS disks. the performance should be there.

a better question should be, how to figure it out driver issues?
The issue with the CPU looks strange and i don´t know how to find out why the cpu data could be not show with xenpm

I think I will make some test with a linux vm look how the performance is there.

@olivierlambert I think it could be both... but how can i figure it out where are the this came from?

it is a fresh installed system.

I have checked the BIOS: PowerManament is set to static Performance
there was no change...

the CPU parameter are still not avail

further the HDD load in the VM is strange, the disk load is without any started app permanently at 100%

High Disk load without any started app:

high CPU load after start without any started app:

Hi @ all,
I am using since about ten year Xenserver and tested it on several platforms.
It runs on all configuration i have every tried and the most of it are not build for such usage.

2 weeks ago I have get an ProLiant DL380p Gen8 with two E5-2680.
At first nothing unusual during installation an migration. But then I tested some Windows 10 VMs and there are extremely slow. I comparison to another system they are about ten times slower.

after some research in the forum I have found the following topic:

xcp-ng CPU low performance issue

If I want to get some CPU information i will get this:

[07:18 localhost ~]# sudo xenpm get-cpufreq-para

[CPU2] failed to get cpufreq parameter

It seem to be xen can´t get clean access to the CPU?

Are there anyone who has solved such a problem?
