Re: [libvirt] Xen config files again

You told me earlier that I can pass the name of the VM (which has a corresponding .cfg file in /etc/xen) to lookupByName() and then use getXMLDesc() to get information in XML format about the VM, but it would appear that at least the first function is only useful for running VM's not for VM's that are not running.

Example to clarify my goals:
I use xen-create-image to create the VM. It puts a config file called host1.cfg in /etc/xen. I would like to have a python script to automatically convert this .cfg file to something libvirt can use to start the VM.
Or another option would be some automated method of creating the VM in a similar fashion as xen-create-image.

I've seen in the src tree that there are functions to read and use Xen
configuration files.  Are these functions available in the Python

mostly interested in doing is parsing the Xen config file and getting
back the XML version that I can store and use later on.

No, these methods are for internal use only. All acccess to the Xen config files must go via the public interfaces and XML format. Internally we use the config file API to convert from XML into the config file format and
