Description of problem: 1] After upgrading /Installing RHVH 4.4, the libvirt is identifying CPU name as Cascadelake-Server for Skylake server. 2] It is also failing to add in the cluster due to missing feature spec_ctrl. Version-Release number of selected component (if applicable): RHV 4.4 How reproducible: Always Steps to Reproduce: 1. Install RHVH 4.4 2. Try to add in IBRS family cluster 3. It fails and complains CPU flag is missing Actual results: The host is not added in the cluster Expected results: Host should come UP in the customer. Additional info:
Milan, duplicate of bz 1854922?
Yes, it looks the same.

Can add RHVH 4.4 Cascadelake server to 4.3 cluster with cpu type Intel Skylake Server IBRS SSBD MDS Family on 4.4 engine 2. Can add RHVH 4.4 Cascadelake server to 4.4 cluster with cpu type Secure Intel Skylake Server Family on 4.4 engine 3. Can add RHVH 4.4 Skylake server to 4.3 cluster with cpu type Intel Skylake Server IBRS SSBD MDS Family on 4.4 engine 4. Can add RHVH 4.4 Skylake server to 4.4 cluster with cpu type Secure Intel Skylake Server Family on 4.4 engine
