In the WebUI, I saw no NIC associated with the machine (maybe the user deleted
it?). So I went ahead and added one:
mysql> select * from nics where instance_id='2071';

However, the IP address assigned in the nics table doesn't match the one in the
vm_instance table:
mysql> select id,name,private_ip_address from vm_instance where name='myhost';
+------+--------------------+--------------------+
| id | name | private_ip_address |
+------+--------------------+--------------------+
| 101 | myhost | 10.1.131.0 |
+------+--------------------+--------------------+
1 row in set (0.00 sec)
Shouldn't that IP have been updated as well?

Hi Kyle,
My suggestion is take nic entry of the vm which is removed (in the same
network) and edit it for your VM.
While editing take care of the values of instance_id, ip, mac_address, state,
default_nic, removed, display_nic and strategy columns.
Thanks,
Jayapal
