Hello everybody,

I am wondering if libvirt community implement features specefic to only one supported hypervisor?

The goal is to support all useful features, even in cases when only one hypervisor currently supports a given feature.

I am trying to set the host name and DNS from within the libvirt xml file in user mode network option (SLiRP). Right now I am using the <qemu:commandline>. My concern is if I want to use Xen or other hypervisors, how I should do the same.

I'm not sure if it is portable to other hypervisors, but the design goal in adding such XML should be something that is generic enough that it might indeed be portable to Xen, even if the initial implementation only supports qemu.

To be honest, I have not used any other hypervisor, except QEMU yet, I am trying to write a code which can be used for any hypervisor libvirt supports, though. And I am not even sure if it is possible to set DNS address and so on the way they are settable in QEMU. Therefore, I was thinking if there is any standard xml element in <interface> which I may use to solve my problem (setting dns, host name , and so on...) with.

On the IRC channel I received a reply that this feature has not been implemented yet, and you are going to support it soon. I am interested to contribute and join the community to imlement this feature if possible. Appreciate pointing me into right direction and thank you in advance.

You are more than welcome to help out. I would start by proposing the particular XML syntax that you think best represents your usage needs, and get feedback on whether it makes sense and seems generic enough to port to other hypervisors. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
