Remove network adapters from a XenServer host

Removed a couple of network adapters from a XenServer host, but they were still showing up in XenCenter. Here's how to remove:

xe pif-list

Note the uuid(s) of adapters you'd like to remove (in my case eth2 and eth3), then for each adapter do:

xe pif-forget uuid=[uuid from previous step]

They should now be gone.
