Description Markus Stockhausen 2014-02-03 18:40:46 UTC

Ovirt allows ony one administrator to connect to a VM console. Shared sessions, so that two admins can see the console concurrently from different clients, are not possible.

This is the main RFE to achieve this goal.

1) virt-viewer must get an enhancment so it connects with VNC option shared to the VM console. BZ 1060425 has been created for that

2) OVirt must create (or at least respect) the qemu emu environment setting SPICE_DEBUG_ALLOW_MC=1 to allow shared spice consoles. During the ticket setting process the disconnect flag must not be generated. BZ 1060573 created for that.

3) OVirt needs a new persistent flag for a VM that enables/disables the shared session setting.

4) Accoring to that flag Ovirt must either create a modified VV file (in VNC case) or modify the XML during VM startup (in SPICE case)

This works via novnc in ovirt 3.3.2 and upwards, I don't know if by accident or
if it is a feature.

Comment 2 Markus Stockhausen 2014-02-26 08:24:26 UTC

VNC will work because it depends on the client. virt-viewer does not open shared consoles. Maybe a workaround could be on server side using sharePolicy=ignore.
See: http://libvirt.org/formatdomain.html#elementsGraphics

SPICE will need more logic on the server side.
