Red Hat Bugzilla – Bug 231785
No display when booting the xen kernel
Last modified: 2009-12-14 15:40:29 EST
Description of problem:
Version-Release number of selected component (if applicable):
When booting the Xen kernel on my laptop, the display remains completely blank
after grub. The kernel appears to boot succesfully; eventually I can log into
the machine from the network. "uname -r" reports the Xen kernel version, "xm
list" shows the host running, but the system console screen is empty.
Using the network login I can then reboot the laptop into the regular, non-Xen
kernel, which boots fine.

dmesg from 2.6.20-1.2933.fc6xen, with multiple BUGs
This bug is still present in 2.6.20-1.2933.fc6xen.
The laptop screen remains turned off, but the kernel appears to boot with the
screen off, eventually I can ssh into this box over the network, and collect
the attached dmesg.
Note that dmesg reports multiple BUGs :-)
