Reserve All Guest Memory (this is a mandatory requirment for SR-IOV but I enable it for all testing VMs)ĮSXi hosts: we use 2 ESX hosts (host10 and host11) for our testing.Regarding the vSphere 6.5 support to SR-IOV, please refer the link below: This blog is to demonstrate network performance (network throughput here only) for a SR-IOV enabled Centos7 virtual machine which is running on vSphere 6.
