Here's what happens:

1. I do a a xml dump of the domU:

[root at xenmaster xen]# virsh dumpxml asterisk > guest.xml
libvir: error : failed to read configuration file /etc/xen/guest.xml

Though there's an error, guest.xml is created and looks okay.

2. I try  to define the domU with the xml file I just dumped (after editing the RAM parameters):

[root at xenmaster xen]# virsh define guest.xml 
libvir: error : configuration file syntax error: expecting a name
libvir: Xen Daemon error : internal error domain with name already exists
error: Failed to define domain from guest.xml

I check domU config file, and nothing has changed: the define really did fail.

3. I undefine said domU:

[root at xenmaster xen]# virsh undefine asterisk
libvir: error : configuration file syntax error: expecting a name
Domain asterisk has been undefined

The asterisk config has been deleted, so it looks good so far.

4. I again try to define the asterisk domU with the xml file I dumped earlier:

[root at xenmaster xen]# virsh define guest.xml 
libvir: error : configuration file syntax error: expecting a name
Domain asterisk defined from guest.xml

I check the domU config, and it's been updated with the changes I made to the xml dump.

I hope that helps.

Ranbir
