[libvirt-users] virt-viewer via ssh to a remote host

[Marc Haber]

Hi,

I have a virtualization host running KVM and libvirt 0.9.12 (on Debian
unstable). I would like to connect with virt-viewer 0.5.4 from a
different host to a domain that has Display Spice configured as
graphics interface.

I can connect to the KVM host using
virsh --connect=qemu+ssh://mh@fan.local/system
and start m KVM domain from there, so I guess that authentication is
just fine.

However,
virt-viewer --connect=qemu+ssh://mh@fan.local/system <domain>
does not work. The easy issue was that virt viewer issues a "nc
fan.local 5900" on the remote host, while the Display Spice agent
listens on 127.0.0.1 only. I could fix that by checking the "listen on
all IP addresses" box in the Display Spice configuration in
virt-manager. After that, I could see the TCP connection to the Spice
agent on the remote host succeed when tcpdumping on the KVM host's lo
interface.

When I invoke virt-viewer when the domain is not running, it says
"Waiting for the guest domain to start", and changes to "Connecting to
graphic server" when I start the domain. When I invoke virt-viewer
when the domain is already running, it immediately says "Connecting to
graphic server", but the domain's console does never show up.

When I invoke
virt-viewer --connect=qemu:///system <domain>
directly on the KVM host, the console shows up alright.
On the KVM host,
virt-viewer --connect=qemu+ssh:///system <domain>
gives the same behavior as the remote invocation, while
virt-viewer --direct --connect=qemu+ssh:///system <domain>
does. So I guess there is something wrong with the tunneling of the
Spice session through ssh.

Am I doing something wrong? I would appreciate any hints.

Greetings
Marc
