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, Intel E5-2640 v3. 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."
if you do not see vmx and/or nx flags, you probably have virtualization disabled in BIOS
Thanks,
