I suppose you mean the name of the bridge from virtual network with ID,
for example 7. 

If you use MySQL as a database the following steps work.

$ onevnet list | grep 7
   7 wiz          oneadmin     test            -               R test 0

$ mysql -u root -p
use opennebula;
update network_pool set body='<VNET><ID>7</ID><UID>2</UID><GID>0</GID><UNAME>wiz</UNAME><GNAME>oneadmin</GNAME><NAME>test</NAME><PERMISSIONS><OWNER_U>1</OWNER_U><OWNER_M>1</OWNER_M><OWNER_A>0</OWNER_A><GROUP_U>0</GROUP_U><GROUP_M>0</GROUP_M><GROUP_A>0</GROUP_A><OTHER_U>0</OTHER_U><OTHER_M>0</OTHER_M><OTHER_A>0</OTHER_A></PERMISSIONS><CLUSTER_ID>-1</CLUSTER_ID><CLUSTER></CLUSTER><TYPE>0</TYPE><BRIDGE>*virbrB*</BRIDGE><VLAN>1</VLAN><PHYDEV/><VLAN_ID>3</VLAN_ID><RANGE><IP_START>192.168.18.50</IP_START><IP_END>192.168.18.254</IP_END></RANGE><TOTAL_LEASES>0</TOTAL_LEASES><TEMPLATE><NETWORK_MASK><![CDATA[255.255.255.0]]></NETWORK_MASK></TEMPLATE></VNET>' where oid=7;
quit

And the next step would be to check if that really changed things:
$ onevnet list | grep 7
   7 wiz          oneadmin     test            -               R virbrB 0

I didn't come up with the `body` data. I just copied it using the
following MySQL query:

use opennebula;
select body from network_pool where oid=7 \G

If something is not right I kindly ask the OpenNebula developers to post
further guidance. Thanks.

Enjoy,
