Migration Restrictions for Setting linkprop=phys-state
You can migrate a virtual network device that has a physical NIC backing device and has linkprop=phys-state
to a target domain that does not have a physical NIC as a backing device (net-dev=
). Because the linkprop=phys-state
constraint is not a hard requirement, if such a domain is migrated to a machine that does not have an available net-dev
value, the constraint is preserved but not fulfilled. The linkprop
property is still preserved as phys-state
and the network device link state shows as link up.
