I'm trying to setup Xen on a Ubuntu 8.04 laptop. I followed the instructions in
Installing Xen On An Ubuntu 8.04 (Hardy Heron) Server
I haven't gotten as far as adding a guest, I'm stuck on the reboot with the Xen kernel.
When I boot, Xen seems to be going OK, and tells me its giving up the VGA. A little time goes on and then the VGA screen clears, after which there is no response to the keyboard or anything more on the screen.
The laptop does in fact answer pings, and in fact accepts ssh connections. However, the ssh connections just hang with no response.
I get the same behavior if I substitute "console=vga" for "console=ttyx" on the grub kernel params. The laptop has no serial port.
I'm running Ubuntu 8.04 currently patched to kernel 2.6.24-20. I did not take the suggestion of using the 2.6.24-16 workaround xen kernel. I thought the network problem it adressed may have been fixed by -20, and at any rate it would not effect the console problem.
