@Forza Actually I have the same "issue", so +1 here.

RE: 2 hosts in a pool, how to force VM to boot on a specific host. (GPUs involved)
@ptunstall In the Advanced settings of the VM, select the host:

RE: Hosts log error in Xen Orchestra
@Danp Can confirm, I also get an "internal error" when trying to download logs.

RE: Bringing modern virtualization in the Arm-powered Datacenter
@gskger XCP-NG on ARM/Ampere will be huge!!!!
The running cost of those machines is a big win over x86. Power is expensive in Europe. Hetzner is in full swing on that front.
And not everything runs in Windows I guess it's only the smaller fraction of all the VM's in the world. -
RE: Epyc VM to VM networking slow
@gskger Returning to this:
Our backups on our business deployment, 2 HPE, (,ProLiant DL325 Gen10 Plus v2,) with AMD EPYC 7543P 32-Core Processor connected via redundant 10G nic's and switched to 10G NAS (QNAP, Synology) for storage and backups we get backup speeds of 80-90MiB/s tops with NBP.
On my Homelab with Protectli Mini PC connected via 10G also to 10G QNAP I get 250-300 MiB/s !!!!!!
This really is a problem for us now since we started with XCPNG 1 yr ago. Slow backup/restore speeds are a hindrance in our backup strategy.
Now that I switched my Homelab from Proxmox (using it for 3yrs) to XCPNG I stumbled upn this speed difference and it is incredible.
I wonder if it is not also related to this issue with EPYC networking.
P.S: I have opened a ticket BUT I wanted ti share this here also.

RE: Epyc VM to VM networking slow
@bleader I stumpled upon this thread and this issue kept me wondering so I did a quick test on our systems:
Running iperf3 on ou HP's with AMD EPYC 7543P cpu's, debian12 to debian12 vm I get
iperf3 -c 192.168.1.19 -P 10
iperf3 -c 192.168.1.19
Same on a HP with Intel Xeon E5-2667
iperf3 -c 192.168.1.113 -P 10
iperf3 -c 192.168.1.113
FREAKY!
Doesn't affect us because we don't have inter-VM traffic to speak off.
