Err, yes we do.
<channel type='unix'>
<source mode='bind'
path='/var/lib/libvirt/qemu/f16x86_64.agent'/>
<target type='virtio' name='org.qemu.guest_agent.0'/>

Yes, I confirmed that it can create the socket for guest agent and
communicate to guest.
Or for the console
<console type='unix'>
<source mode='bind'
path='/var/lib/libvirt/qemu/f16x86_64.console'/>
<target type='virtio'/>
</channel>
though you really want to use type=pty for consoles, so that 'virsh
console'
works correctly.

But It is not enough. Because I use the socket for VirtIO console, i.e.
gives the option '-device virtconsole,chardev=...,name=foo' for qemu.
And I read the source code, but found funny...
In src/conf/domain_conf.h, struct _virDomainChrDef is
struct _virDomainChrDef {
...
union {
int port; /* parallel, serial, console */
virSocketAddrPtr addr; /* guestfwd */
char *name; /* virtio */
} target;
...
It is written that virtio must use char *name.
But in docs/schemas/domaincommon.rng and others, VirtIO Console use only
int port.
Thoug I do not understand that which should be used, I attaches the
patch for using *name.
P.S. I can not use GIT, because live in restricted network.
