[vfio-users] CPU Provisioning Question.

[Mario Goebbels]

I was wondering about this for related matters. So it is advised to leave
some breathing room for the host, even if only one VM is running? I also
have 6 hyperthreaded cores, I've set up the VM currently with 4 of them (4
cores, 2 threads), leaving the other two for the host and iothread. Would
using all 6 in the VM cause issues when the VM comes under high load,
because the host may get choked out of CPU time?

Regards,
