Hi
I've just joined this list and this is my first post, so please be
gentle :) I also apologise if I am posting to the wrong list :(
I have setup Apache VCL in a test environment to evaluate for deployment
for the Faculty of Science at the University of New South Wales, Sydney,
Australia.
I have been working with both VMWare and KVM (on CentOS 6.3).
I have managed to create a base image on the VMWare system but can't
seem to get one created on the KVM system.
I can't find any reference to the specifc problem that I am having in
the list archives, though I have only looked briefly at this years
archives (July to January 2012).
The logs of the failed image creation is forwarded below.
It looks to me as if the problem is when the the 'libvirt.pm' module is
trying to find the domain/virtual machine to be used as the base image
on the kvm host.
It successfully runs the 'virsh list --all' command and gets the result
correctly:
SNIP

info from kvmhost2:

SNIP
But then when it tries to use that information to dump the XML config
for the domain, there seem to be extra space added to the front of the
domain name so that the 'virsh dumpxml' command fails:

|16421|54:54|image| error: Domain not found: no domain with matching name '

SNIP
I am not sure if this is something I have done wrong with the
configuration or what but any advice would be useful.
Regards,
Adrian
