[virt-tools-list] virt-viewer via ssh -X

[Kirkpatrick, Jeffrey W]

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.

 Try to use the -Y switch instead of the -X switch or put ForwardX11Trusted=yes in your ssh_conf file http://x.cygwin.com/docs/ug/using-remote-apps.html
