Dear all: I am trying to deploy openstack on xen hypervisor.Since XenSever or XCP is not available on our customized virtulization platform. We decide to use libvirt on xen as a middleware operating the xen hypervisor. But when I try to boot a instance , xen failed to response and I find the error in my nova.log as follows:
3645be21-9b5b-4718-9c9f-f6ba3588f7b4] libvirtError: this function is not supported by the connection driver: virNWFilterDefineXML 2012-08-24 09:17:25 TRACE nova.compute.manager [instance: 3645be21-9b5b-4718-9c9f-f6ba3588f7b4]
It seems that libvirt doesn't support virNWFilterDefineXML on xen,
Unfortunately, your analysis is correct - no one has yet contributed a patch to port NWFilter usage to the xen driver.
Is there any good solutions? Or how much work should be done to add this function to libvirt?
You could use the code in the qemu driver as a starting point, if you are interested in adding the functionality yourself. I don't use xen much myself, so I probably won't write such a patch, but I will review any patch posted by others. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
