[ovirt-users] Re: HostedEngine start error: could not find capabilities for arch=x86_64 domaintype=kvm

Hello, I'm importing a VM into a new oVirt environment that is in 4.3.10: the new host is the same as the previous one (only difference it is in 4.3.10 while the old one in 4.3.9). This VM acted as a single host HCI environment (with 4.3.9). I imported the storage domain containing the VM and its disks and the VM boots ok. Now its Hosted Engine VM (that is so a nested VM) doesn't start. I think it was good when I stopped/detached it... and so I would like to cross check and verify if I missed something configuring the new environment or something changed from 4.3.9 to 4.3.10 In vdsm.log I see this reason: [snip]

libvirtError: invalid argument: could not find capabilities for arch=x86_64 domaintype=kvm The relevant parts of the generated xml in vdsm.log seems: [snip]

The configuration of the new 4.3.10 physical oVirt environment that contains the VM has this cluster cpu type: Intel Skylake Server IBRS SSBD MDS Family Do I have to change it to anything else? I don't remember how it was set in 4.3.9 Thanks in advance, Gianluca
