No, when I go to the Status Display in xsconsole, I get:

Status Display

<Unknown> <Unknown>
<No network configured>
And when I go to "Network and Management Interface, I get:
Currently, no management interface is configured.

I am ssh'd into the xenserver via its management interface, so I know
it's up.
[root@hv1 ~]# xe pif-list
The master says the host is not known to it. Perhaps the Host was
deleted from the master's database? Perhaps the slave is pointing to the
wrong master?
host: e0e2c7af-8adb-49d7-bae5-51dcdb43aa16

I've also tried forcing it into the resource pool that exists, and that
fails as well.
