[ovirt-users] adding new host failed with error "CPU does not match the Cluster CPU Type lscpu"

i get the below error when i try to add a new kvm host to the cluster. I know that the cpu is a haswell. if i run "virsh capabilities" it returns <model>Haswell-noTSX-IBRS</model>. My KVM server is redhat 8.4 fully patched today on an DL-360 Gen9. oVirt is at 4.4.7.7-1.el8. i have tried many diffent CPU settings for the cluster and none of them work. this is new oVirt install. ERROR: "The host CPU does not match the Cluster CPU Type and is running in a degraded mode. It is missing the following CPU flags: vmx, model_Haswell-noTSX, nx. Please update the host CPU microcode or change the Cluster CPU Type."
