Re: [Xen-users] cloning domains

["Arie Goldfeld" <arik.goldfeld@xxxxxxxxx>]

The guest domains I've created by the cloning process described by Daniel have a problem with network connection.

Does anybody have an idea what might be the problem? Please see the exerpt from xend.log:

Best bet at this time is to extract the guest config

  virsh dumpxml [guest name]  >  guest.xml

Edit the guest.xml to change the name, UUID, MAC address & point to a
copy of the filesystems, then load the config back into XenD

  virsh define guest.xml

In the next update of  python-virtinst in Fedora we are also adding a
command explicitly for cloning existing guests called 'virt-clone'
which will make this task much much easier :-)

Dan.
