virt-viewer does not connect to libvirtd: result: no console access to running VMs

[Thomas Schweikle]

on a client: virt-viewer -c $server vm &

The virt-viewer window opens, then immediately closes again. Trying the same with virt-manager: no console, but message: "Error: viewer connection to hypervisor host got refused or disconnected!". Since this ran before I assume i a bug.

Server:
ii libvirt-bin 0.9.8-2ubuntu17 programs for the libvirt library
ii libvirt0 0.9.8-2ubuntu17 library for interfacing with different virtualizat

Client:
ii virt-manager 0.9.0-1ubuntu3 desktop application for managing virtual machines
ii virt-viewer 0.4.1-1ubuntu2 Displaying the graphical console of a virtual machine

Connections to a debian host are working. Only those to Ubuntu precise are not working.

Socket is there and has neccessary rights set. Users are in group libvirtd. It does not work for users or root.

qemu+ssh://root@server/system does not work,
qemu+tcp://server/system does not work,

Doesn't work for local or remote connections. Enabling VNC via tcp without encription: same. With encription same again.

[Thomas Schweikle (tps)]

Doesn't matter if client is precise or oneiric. Both do not work against a precise server, while both work against a debian testing or an oneiric server.
Something is broken using precise on the server side!
