Inability to reprovision a configured guest automatically
If you have already provisioned a guest and then re-enter the add virtualization xml command, you see an error message, which indicates the guest is already configured, similar to the following:
vyatta@vyatta:~$ add virtualization xml /home/vyatta/vr5600.xml image /home/vyatta/vr5600.qcow2 iso /home/vyatta/config.iso
RPC failure: [ERROR] - Guest "vr5600" has already been configured at /opt/vyatta/share/perl5/Vyatta/Configd.pm line 193.
vyatta@vyatta:~$
This operation is by design.
