Here's what happens:
1. I do a a xml dump of the domU:
[root@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.
Were you in the /etc/xen directory when you ran that command ? It looks
like you were since it mentions /etc/xen/guest.xml
Basically /etc/xen should only ever contain the master Xen config files.
Never create any other type of files in there. In this case the guest.xml
file is getting parsed as if it were a Xen config file & thus you see the
error.
2. I try to define the domU with the xml file I just dumped (after
editing the RAM parameters):
[root@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.
That's a bug. If you update to the recently released 0.2.3 libvirt RPMs
it should be fixed. We pushed them to Fedora last week IIRC, although
its possible they're still only in updates-testing.
With the new version you should be able to define the VM, without first
having to undefine it.
