Description of problem:

If two administrators need access to the same VNC console of a virtual machine they can do it with the vnc option "shared access" (e.g. TightVNC). virt-viewer currently only opens exclusive sessions so the second login kicks out the first login.

Version-Release number of selected component (if applicable):

virt-viewer 0.6.0


Implementation idea:

The first thing to accomplish is a new flag in the .vv file that allows to open a shared or exclusive connection. E.g. SHARED=0/1

After reading that file virt-viewer has to set the shared option for opening the connection depending on that flag. If I read it right that must be somewhere in  virt-viewer-session-vnc.c

...
vnc_display_set_shared_flag(self->priv-vnc,sharedFlag);
ret = vnc_display_open_host(self->priv-vnc,...)
