Hello,
I'm trying to get my first HVM domU installed (another Debian domU is
already working under the same dom0). I intend to install the guest OS
from a bootable CD-ROM.
But when I create the new HVM domU with 'xm create xp1-cd.cfg' , I don't
get the expected installation-window and find this in
/var/log/xen/qemu-dm.6575.log:
domid: 6
qemu: the number of cpus is 1
shared page at pfn:17fff, mfn: 30cec
buffered io page at pfn:17ffd, mfn: 30cee
---------------------- DirectFB v0.9.25 ---------------------
(c) 2000-2002 convergence integrated media GmbH
(c) 2002-2004 convergence GmbH
-----------------------------------------------------------
(*) DirectFB/Core: Single Application Core. (2006-10-17 10:09)
(*) Direct/Memcpy: Using MMX optimized memcpy()
(!) Direct/Util: opening '/dev/fb0' failed
--> No such device
(!) DirectFB/FBDev: Error opening framebuffer device!
(!) DirectFB/FBDev: Use 'fbdev' option or set FRAMEBUFFER environment
variable.
(!) DirectFB/Core: Could not initialize 'system' core!
--> Initialization error!
Could not initialize SDL - exiting
Now I'm looking for clues, why SDL can't be initialized. A /dev/fb0
seems to exist:
xen# ls -la /dev/fb0
crw-r--r-- 1 root root 29, 0 2006-11-11 15:07 /dev/fb0
Anyone with an idea?
Cheers,
Oliver
P.S. My domU config (xp1-cd.cfg):

the old
# one;
# "preserve", meaning that no clean-up is done until the domain is
# manually destroyed (using xm destroy, for example); or
# "rename-restart", meaning that the old domain is not cleaned up, but is
# renamed and a new domain started in its place.
