Having the same issue, tried all different kernels and patches with no luck. Found this thread here and have some hope. I have both the m.2 and usb versions of the coral. So I have a pcie usb 3.2 adapter card coming tomorrow and I am going to try to pass the card through instead of the m.2 and hook up the usb version see if I can get some performance. I'll let ya guys know if it is acceptable speed.

Passing through the usb adapter I am getting roughly 30ms response times which is acceptable. Definitely not as fast as the m.2 version but good enough to keep me from buying a mini-pc or SBC. I would love to switch to the m.2 if someone could post here if they get a success. Just a strange side note, I couldn't get it to list in xoa and use the gui to do the passthrough. I had to manually hide it from the dom and pass the usb adapter to the vm. I couldn't figure out how to refresh the pci list and tried doing reboots to see if it would pick up the new device but no luck. If anyone knows how to refresh that list I'd be interested.

Thanks,
SFD

I actually had more cores assigned to the vm earlier. Maybe that caused it.

Thanks for responding @jedimarcus

I am just missing something possibly... The procs say cpu 1, 2, 3 and they are all 1.3% or lower. If you are referring to the lower area, in the table. That is 30% out of 300% I believe. Again I could just be misunderstanding how its being reporting. This is why I am asking. What i was expecting was, the breakout of cpu 1, 2, and 3 at the top left of htop to match the xoa chart, but these are different values?

Thanks!

Hi I am pretty new to xcp-ng and xoa. The cpu reported in the graphs doesn't match the actual. Or maybe I don't understand something? I also went on to the host and verified the cpu usage matches htop's values. The XOA graph says a pretty consistent 38% usage of one of the cpus.
