RHEL 5.5 live migration fails in XEN

Posted on

 I have two XEN hosts, and to migrate a machine has given me an error and has failed to complete the operation.

 

HOST B  ----->>>>  HOST A

 

 

HOST B (RHEL 5.5  2.6.18-194.8.1.el5xen) 64bits and xen-3.0.3-105.el5_5.2:

After that the machine is still in the HOST B (origin) and the state"migrating-www01"
 
Thanks.
