[Pkg-libvirt-maintainers] Bug#706059: libvirt-bin: libvirt seems unable to connect to xen using unix sockets

[Michael Deegan]

Package: libvirt-bin
Version: 0.9.12-11
Severity: normal

Hello,

libvirt seems to default to attempting to connect to xen using the insecure port 8000
HTTP interface, despite documentation everywhere saying that the HTTP interface
is bad for security:

    root at mordac:/home/michael# virsh connect
    error: Failed to connect to the hypervisor
    error: unable to connect to 'localhost:8000': Connection refused

So I've configured xend to use the unix socket interface instead:

    root at mordac:/home/michael# grep ^[^#].*xend-unix /etc/xen/xend-config.sxp
    (xend-unix-server yes)
    (xend-unix-path /var/run/xend/xend.sock)

However, I am having difficulty convincing libvirt to use this interface. My
reading of http://libvirt.org/uri.html suggests that these *ought* to work:

    root at mordac:/home/michael# virsh -c ///var/run/xend/xend.sock
    error: no connection driver available for No connection for URI /var/run/xend/xend.sock
    error: failed to connect to the hypervisor

    root at mordac:/home/michael# virsh -c xen:///var/run/xend/xend.sock
    error: internal error unexpected Xen URI path '/var/run/xend/xend.sock', try xen:///
    error: failed to connect to the hypervisor

    root at mordac:/home/michael# virsh -c xen+unix:///var/run/xend/xend.sock
    error: internal error unexpected Xen URI path '/var/run/xend/xend.sock', try xen:///
    error: failed to connect to the hypervisor

    root at mordac:/home/michael# virsh -c xen+unix:///
    error: unable to connect to 'localhost:8000': Connection refused
    error: failed to connect to the hypervisor

    root at mordac:/home/michael# virsh -c xen:///
    error: unable to connect to 'localhost:8000': Connection refused
    error: failed to connect to the hypervisor

I'm open to the possibility that it is simply a case of error messages being
incorrect or misleading.
