I'm using an OpenSolaris image provided at the top of this page:
Unfortunately, it isn't PAE-enabled, so it won't work with the latest 
versions of Xen.  Apparently Solaris-32 is now PAE-capable, so I've posted 
a message on the OpenSolaris board requesting an update to the image.

Hmm, the error seems to no longer occur, probably user error.  It looks
like the domU is booting but still inaccessible.

I've been trying to get the framebuffer approach to work, with limited 
success.  I can get the domU's grub window to pop up, but once it starts 
to boot Solaris the console turns black and freezes.

Googling around has shown very little explanation or documentation of how
this virtual framebuffer stuff works, so I may be doing something wrong.  
I set the following in the config file:

Intel VT-x
