olivierlambert I tried but getting this error when turning on the VM
INTERNAL_ERROR(xenopsd internal error: (Failure
"Error from xenguesthelper: Populate on Demand and PCI Passthrough are mutually exclusive"))
Not sure what it means
EDIT: after googleing it seems that static and dynamic memory has to be the same:
Just updated to lastest commit https://github.com/vatesfr/xen-orchestra/commit/4bd5b38aeb9d063e9666e3a174944cbbfcb92721
It's fixed now. Working wonderfully. Thanks!
I got it working!

For future reference if anyone finds this with google:
I had to " sudo chmod -R 777 /dev/dri" inside the Ubuntu VM, otherwise it didnt work.
I'm using binhex plex docker image, I have to add the device to the container. It's really easy with portainer:
The "/dev/dri/" part is the important
PS: olivierlambert there is a typo in the xcp docs, a space is missing in Step 5:
https://docs.xcp-ng.org/compute/#5-put-this-pci-device-into-your-vm
This copy/pastes as:
xe vm-param-set other-config:pci=0/0000:04:01.0uuid=<vm uuid>
It should be:
xe vm-param-set other-config:pci=0/0000:04:01.0 uuid=<vm uuid>

bullerwins nice catch, the fix is trivial with such a detailled error : https://github.com/vatesfr/xen-orchestra/pull/6830
nice! as soon as it's merges I'll update it and check. I'm so happy if this report helped you guys in any way!

bullerwins XO Proxy Appliance deployment is not supported in XO built from sources.
my bad, it used to work a few months back I believe
olivierlambert said in XOA Proxy Error when updating:
I missed that in the original message, indeed
FYI bullerwins there's no such thing as XOA built from sources, you have either:
- XOA is Xen Orchestra virtual Appliance, that's the VM we distribute with pro support and QA/stable channel, updater and such
- XO from the sources is from Github, without pro support but community support, no QA no stable version, no udpater and such
Thanks, I got confused with the naming, I'm using the second option.
As a workaround I used a VPN to manage the remote XCP-ng host, thanks!
julien-f Thank you so much, I restarted the XOA built from source ubuntu VM and now it works! (how could I not thought of this before #1 rule in IT, turn off and on again).
Thanks a lot for the support.
Soarin Hi! Would you mind sharing what config did you use for openvpn?
Did you install openvpn in the xcp-ng host? in a vm?

have you tested without the 8.3 updates? The results seem still low. Any improvement?
hi olivierlambert ! it's the nomenclature bleader used in the report table, sorry for the misunderstanding:
https://xcp-ng.org/forum/post/67750
v2m 1 thread: throughput / cpu usage from xentop³
v2m 4 threads: throughput / cpu usage from xentop³
h2m 1 thread: througput / cpu usage from xentop³
h2m 4 threads: througput / cpu usage from xentop³
it's vm to vm and host (dom0) to vm.
Btw I'm super happy to do any more test that could help, with different kernels, OS's, xcp ng versions... whatever you need.
PS: vm to host resulted in unreachable host even though I could ping from vm to host just fine, I checked the iptables are blocked for the iperf port but open to ping, but I didn't want to mess with dom0.

xerxist have you tried with the 8.3 beta of XCP-ng? I believe it's got a newer kernel maybe?
xerxist my ubuntu 22.04 install came with kernel 5.15, i have it updated regularly but it doens't update the kernel it seems. But newer fresh installs of ubuntu 22.04 install a newer kernel. I'll check out if the kernel needs to be manually updated
xerxist in BIOS mode, i would say it was the default for my ubuntu VM
xerxist are you using Plex in docker or native install?
