The problem I face now is the KVM hosts shows this error Host kvm1 moved to Non-Operational state as host CPU type is not supported in this cluster compatibility version or is not supported at all I modified /etc/modprobe.d/kvm.conf and changed options kvm_amd nested=0 to options kvm_amd nested=1 reboot the kvm host but still getting same error, I verified the modification and seems good [root@kvm1 ~]# cat /sys/module/kvm_amd/parameters/nested 1 In Windows 11 I have hyper-v off and Memory Integrity is also off. Am I missing any additional steps? Thanks
