4.3.4.2. Re-ordering NICs
It is not possible to directly rename a PIF, although you can use the
pif-forget
and
pif-introduce
commands
to achieve the same effect with the following restrictions:
•
The XenServer Host must be standalone and not joined to a resource pool.
•
Re-ordering a PIF configured as the host's management interface requires additional steps which are
included in the example below. Because the management interface must first be disabled the commands
must be entered directly on the host console.
For the example configuration shown above use the following steps to change the NIC ordering so that eth0
corresponds to the device with a MAC address of 00:19:bb:2d:7e:7a:
1.
Use XenCenter or the
vm-shutdown
command to shut down all VMs in the pool to force existing VIFs
to be unplugged from their networks.
xe vm-shutdown uuid=<VM UUID>
2.
Use the
host-management-disable
command to disable the management interface:

3.

command to remove the two incorrect PIF records:
