[ovirt-users] Re: Network Performance Issue on oVirt Node Using Intel Platinum 8562Y+ (Sapphire Rapids) CPU

I just want to highlight that the issue only occurred on ubuntu VMs. There are other VMs running on the same host that all work fine. Some one please help me on this other VM ( Rocky 9.3 ) on the same host.
