This is a very old cpu (Q206):

So chances are you will never be able to migrate from the AMD
FX(tm)-8150 to the Intel Xeon since proxmox does not specify a lowest common cpu denominator between the 2 cpu's unless you manually disable some cpu flags in the config file for your VM's. As I recall it this was also the case somewhere 2.x or maybe early 3.x.
