Hi,
I have a weird and fatal problem with my virt-manager.
Whenever I connect to one of my currently running Linux VMs on my (remote) QEMU machine, virt-manager hangs at "connecting to graphical console for guest"
If I connect to a machine which has just started up, all works just fine. If I close the connection to that machine and then reconnect, all works fine.
But as soon as I quit virt-manager, restart virt-manager, and reconnect to the host, it gives me this problem. Rebooting and then starting virt-manager again also does not solve the issue.
When I click "Open" on a VM, it DOES asks me for the SSH password (using SSH+VNC tunnel), accepts it and then just hangs.
When I then close the window to this VM, virt-manager crashes and I have to force quit it.
All my Linux VMs are Debian Lenny (stable), running in standard text mode (what is it, 80x25?).
Now the weird part: I also have a Windows VM on this machine, and this one NEVER fails to connect!!
I can connect, reconnect, quit virt-manager, open it again, and it still works! This really baffles me.
Help would be appreciated solving this issue, because as it is I can not take over my Linux VMs while they're running, and that's kind of the whole point ...
some technichal information:
Tried this with virt-manager version 0.5 up to version 0.8.2 under Ubuntu (latest release) AND under Fedora Core 12.
Could reproduce this every single time.
