Public bug reported: Got the following errors (listed below) when trying to enter a KVM Guest running Ubuntu desktop 11.04 on top of a KVM Host running Ubuntu server 11.04 install. This was done from a virt-manager running on a 11.04 desktop using ssh over to the server. The "entering" mentioned was merely to move the mouse to within the VM viewer.
I could still login to the KVM guest with ssh, though. I tried shutting down the KVM guest from within using 'shutdown -h NOW', but while this took down the OS, it apparently didn't properly shut down the actual VM instance. When trying to use virt-manager (remotely, as mentioned) to forcefully shut it down, this didn't work out either - just hanging the GUI for a little while, then stating that the operation timed out. When using virsh when logged into the Host, I get: virsh # destroy Store error: Failed to destroy domain Store error: Timed out during operation: cannot acquire state change lock Then, after following some ideas from.. https://bugzilla.redhat.com/show_bug.cgi?id=676205 .. I now have a situation where virsh list doesn't even return: endre@SixCore:~$ virsh Welcome to virsh, the virtualization interactive terminal. .. virsh # list Id Name State ---------------------------------- 17 NewDisk running [.. hanging .. "Store" should have been printed here ..] Today (the next day), I tried virsh list again, and this time it worked out, with Store listed as "running". I then tried connecting via virt-manager, but when trying to go into the machine (virt-viewer?) I get "Connecting to to graphical console for Guest", just hanging. I then tried to forcefully kill the VM again ("Force off" in virt- manager), but this yields the following traceback. Notice the "libvirtError: Timed out during operation: cannot acquire state change lock".
