Yes I have the DISPLAY set. The virt-viewer GUI actually does display back to my desktop, though the fonts are jumbled and after a few minutes it dies. I tried the -Y flag. Virt-viewer launched, but it immediately gave me an error that I can't read because the font is jumbled and then closed. Best Regards, Jeffrey W.
