I suddenly found that virt-manager suddenly stopped working, throwing in a "RuntimeError: could not open display"
Has anyone seen this before? the same thing happen to "virt-viewer" as well:root rakcal ~]# echo $DISPLAY localhost:10.0 [root rakcal ~]# virt-manager Traceback (most recent call last): File "/usr/share/virt-manager/virt-manager.py", line 383, in <module> main() File "/usr/share/virt-manager/virt-manager.py", line 286, in main raise gtk_error RuntimeError: could not open display
[root rakcal ~]# virt-viewer winxp1 Cannot open display: Run 'virt-viewer --help' to see a full list of available command line options
Does anyone know what might be the problem? Reinstalling "virt-manager" didn't bring any good. Any help would be appreciated.
