Since qemu already uses rpc mechanism, I've found it easy to
mix-and-match by doing this in two terminals both logged in as root, and
both located in a libvirt.git checkout directory (if you don't mind
building as root; if you do mind building as root, then have three,
where the third is a regular user running as non-root to do the builds):

setup:
1# git clone libvirt ...
1# cd libvirt
1# ./autobuild.sh --system
1# apply patches I'm interested in testing
1# make
2# cd libvirt

old libvirtd server, old virsh client:
1# service libvirtd start
2# virsh ...
1# service libvirtd stop

old libvirtd, new virsh
1# service libvirtd start
2# tools/virsh ...
1# service libvirtd stop

new libvirtd, old virsh
1# daemon/libvirtd
2# virsh ...
1# Ctrl-C

new libvirtd, new virsh
1# daemon/libvirtd
2# tools/virsh ...
1# Ctrl-C

That gives me testing of all four protocol combinations, assuming that
the installed version is a current release without my patch, and my
just-built in-tree version has my patch.  No need to complicate protocol
testing with multi-host qemu+ssh:// stuff.
