I figured it out, by they attempt to change the VM CPU family from old
VM's, as a last try to get it work again.
After i had a live upgrade to 4.2 with running VM's and shutdown them
down they all dead with disabled network and disks.
No delight to delete them all and recreate them, the other way.
Have a nice day.
