Hi, Would it be possible to have a completely separate (from qemu) userspace backend http://hg.et.redhat.com/cgi-bin/hg-kvm.cgi/xenner/file/6b53579b4b15/blkbackd.cThat became the xen blk backend in upstream qemu later. Bitrotted a bit I suspect, probably needs some patches to work with recent xen libraries. Also you might want to re-sync the block drivers with qemu. Is qemu modular in any way and could support a module build completely separately? No, although the discussion comes up now and then whenever this should be changed. Especially splitting the block drivers into a shared library is considered useful, but nobody did the work yet. Also note that qemu provides userspace xen backends already (pvfb, optionally console), so allowing it to handle disk too looks natural ;) cheers, Gerd _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
