Hi, when you go to the Host details, General tab, there is a CPU Type field. The info icon should list all CPU types supported by the host. Screenshot from 2020-07-22 14-25-36.png Hope that helps.

Missing CPU features : model_IvyBridge, ssbd, spec_ctrl   3.I think the problem is on cluster’s cpu type setting, but which one should I chose to fit for the host?             _______________________________________________ Users mailing list -- users(a)ovirt.org <mailto:users@ovirt.org> To unsubscribe send an email to users-leave(a)ovirt.org <mailto:users-leave@ovirt.org> Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/MN43IHE7V3Y... _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/AGXNYKDTD24...
