Currently all VMs created by SolusVM2 are with host-passthrough CPU configuration. As per QEMU's official docs, live migration is safe only if the CPU models on the hosts that the VM is moved between are the same model.
It appears a better way to handle this would be to have the ability to have the ability for Named models and optionally the ability to specify CPU features. This will allow for greater flexibility when setting up VM hosts.
