At least Xen supports backend drivers in another domain (aka "driver domain"). This patch introduces XML config option for such setting as 'domain' attribute of 'source' element. Verification its content is left for the driver.
In the future same option will be needed for USB devices (hostdev objects), but for now libxl doesn't have support for PVUSB.
Signed-off-by: Marek Marczykowski-Górecki <marmarek@invisiblethingslab.com> --- Changes in v2: - describe in docs/formatdomain.html.in - enforce empty domain tag (only 'name' attribute allowed)
Changes in v3: - change <domain name='xx'/> element to domain='' attribute of source element - this is more logical place - grammar of docs
Changes in v4: - revert back to separate element, named <backenddomain name='xx'/>
Meta-note (don't feel bad about it this time, but food for thought for future submissions): It's a little bit easier on reviewers to send a patch series revision (in this case, v4) as a new top-level thread rather than buried in-reply-to an existing thread. For now, that just seems to be an unwritten convention on libvirt (the qemu project has actually documented it: http://wiki.qemu.org/Contribute/SubmitAPatch - but their policies are sometimes stricter than what we require here, so read that page with a grain of salt). Of course, a patch to libvirt's HACKING to make it an explicit convention might not hurt :) -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
