I am working on libvirt development and I wanted to add a custom tag to the libvirt xml to add a new feature to the VM. I am having trouble getting started with this. It would be really helpful if you can help me get started with this and guide me on what part of the source code that has to be modified to achieve the goal. It would help if we knew more information about what you wanted.

What I would like to do is that I want to add a new tag to the xml file which which when parsed should have an effect on the cpuset value of the vcpu tag. Thus starting the VM with a particular set of CPUs to run on. I am not sure on to implement this since I am new to development by making changes in the source code. It would be really helpful if u guide me to achive the goal.

This is already possible, via the 'cpuset' attribute of the top-level <vcpu> element: http://libvirt.org/formatdomain.html#elementsCPUAllocation -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
