Try this homeboy...

1) Type 'netstat -nat' at the command line and see if you have any VNC
servers listening, they'll be port 580x or 590x, 'x' being what number Xen
has given (or you have assigned) the VM.

2) It might sound stupid but assuming your VM starts (you see it with xm
list), commenting out the VNC/SDL lines can make it run in some kind of
different/faster mode...

3) try a stdvga = 1 instead of the VNC lines, a different, albeit slower
mode...

Dear Xen community,

I have Xen 3.0 installed on RedHat Linux Enterprise RHEL4U2.   "xend
install" runs fine with no error messages.

=20

However, when I start "xm cr guest-vmx.conf" I do not get any new window
open for the new guest OS.  "xm list" shows that the vmx has started and
seems to be working fine (just for testing, when I type "xterm" an X
window opens OK).

=20

Any idea how to get a window open for the guest OS?

=20

=20

"xm list" produces the following output:
