From my perspective, there's literally money on the ground for any virtualization platform to pick up VDI with Intel. The GPU's are affordable and performant for VDI work. They currently work with Openshift and Proxmox is at work on it.

RE: Centos 9 . why nobody use this OS?!
When IBM/RedHat "killed" CentOS, the rest of the world took a hint and left. Companies and projects left CentOS in droves as the future of their products were in jeopardy due to the loss of CentOS.
At this point, the damage is done.

RE: XOA/XO from Sources S3 backup feature usage/status
@Andrew Thanks for that added detail.
Your success to Wasabi is encouraging. Perhaps Planedrops performance issues with BackBlaze B2 is related to a specific combination of implementation of S3 between BackBlaze and XO.
Things to test:
XO to AWS
XO to Wasabi
XO to BackBlazeTheoretically, the performance should be the same to all S3 endpoints.

RE: Epyc VM to VM networking slow
@Seneram If you search the forum you'll find other topics that discuss this. In January/February 2023 I reported it myself because I was trying to build a cluster that needed high-performance networking and found that the VM's couldn't do it. While researching the issue then, I seem to recall seeing other topics from a year or so prior to that.
Just because this one thread isn't two years old doesn't mean this is the only topic reporting the issue.

RE: Epyc VM to VM networking slow
While I'm very happy to see this getting some attention now, I am a bit disappointed that this has been reported for so long (easily two years or more) and is only now getting serious attention. Hopefully it will be resolved fairly soon.
That said...If you need high-speed networking in Epyc VM's now, SR-IOV can be your friend. Using ConnectX-4 25Gb cards I can hit 22-23Gb/s with guest VM's. Obviously SR-IOV brings along a whole other set of issues, but it's a way to get fast networking today.

RE: nVidia Tesla P4 for vgpu and Plex encoding
@olivierlambert As mentioned in another thread...Intel Flex GPU's seem primed for this. nVidia is closed and license greedy. AMD seems a little lost and wandering. Intel has said, "No licensing...Just use it." but they require some development.
It should be relatively easy to incorporate the Intel Flex GPU's, but I'm not sure if the newer kernels are required. That might be where the wheels fall off for now.

XOSTOR to 8.3?
Apologies if I've missed this...But has XOSTOR been made compatible to 8.3? It seemed last I checked it was listed as 8.2 only.

RE: Intel Flex GPU with SR-IOV for GPU accelarated VDIs
@sanjay
Definitely in agreement here. Getting Flex integration with XCP-ng is a no-brainer to me. Hopefully Vates is working on it. If not...Maybe there's a way to fund or prioritize the development? -
RE: Epyc VM to VM networking slow
The past couple of days have been pretty nuts, but I've dabbled with testing this and in my configuration with XCP-ng 8.3 with all currently released patches, I top out at 15Gb/s with 8 threads on Win 10. Going further to 16 threads or beyond doesn't really improve things.
Killing core boost, SMT, and setting deterministic performance in BIOS added nearly 2Gb/s on single-threaded iperf.
When running the iperf and watching htop on the XCP-ng server, I see nearly all cores running at 15-20% for the duration of the transfer. That seems excessive.
Iperf on the E3-1230v2...Single thread, 9.27Gbs. Neglibile improvement for more threads. Surprisingly, a similar hit on CPU performance. Not as bad though. 10Gbps traffic hits about 10% or so. Definitely not as bad as on the Epyc system.
I'll do more thorough testing tomorrow.

RE: Epyc VM to VM networking slow
@nicols Agreed. I'm pretty sure this is a Xen/Epyc issue.
This evening I'll build a couple of VM's to your config, run iperf, and report back the results.
