trying to migrate a VM from one host to another, a big VM with 96GB of RAM, I found that when the migration completes, the VM goes to a paused satte and cannot be resumed. The libvirt/qemu log it gives is this:

If you're running a guest on an Intel machine without unrestricted mode
support, the failure can be most likely due to the guest entering an invalid
state for Intel VT. For example, the guest maybe running in big real mode
which is not supported on less recent Intel processors.
