Hello, my environment was oVirt 4.3.10 with an external engine and 3 hosts. I have updated to 4.4.3 the whole infra, but know if I go and update the cluster to 4.4 I get the message in this window: https://drive.google.com/file/d/1hfs4FC8uZ-EjiCzQyitA3945U0Knnz2m/view?us... What is the reason for it? My Cluster is with Cluster CPU Type: "Intel Westmere IBRS SSBD Family" The signalled 'hostmaster' VM is a powered off VM used in the past to test nested virtualization and in "Virtual Machines" page aside it I see an exclamation mark with "The VM CPU doesn't match the Cluster Cpu Type" The VM is set as custom, optimized for Server Custom Chipset/Firmware Type "Cluster default (i440FX Chipset with BIOS)" Custom Emulated Machine (in grey): "Cluster default(pc-i440fx-rhel7.6.0)" Custom CPU (in grey): "Cluster default(Intel Westmere IBRS SSBD Family)" What I'm expected to change? Thanks, Gianluca
