problem trying to create an Ubuntu dapper VM ...

[rongeens7]

All,

 I am experimenting somewhat with kvm on an
ubuntu edgy system, and am now trying to install
a plain ubuntu dapper from CD into a VM.
The problem is that I cannot get past the lilo prompt,
in fact the Qemu process craches immediately after doing
starting up its bios.

I made the following stacktrace:
Program received signal SIGABRT, Aborted.
[Switching to Thread -1212492112 (LWP 24692)]
0xffffe410 in __kernel_vsyscall ()
(gdb) where
#0  0xffffe410 in __kernel_vsyscall ()

#7  0x08052bcb in main (argc=374, argv=0x0)
    at /data/work/devel/kvm-7/qemu/vl.c:6366

The printout on the screen is
$ sudo /usr/local/kvm/bin/qemu -hda /data/images/ubuntu1.img
-cdrom /data/personal/archive/iso/ubuntu606.iso -boot d -m 512 -std-vga
Password:
vga_bios_size 0
exception 13 (0)
Aborted (core dumped)

(The same is true when I ommit the -std-vga option)

The stacktrace indicates that the abort is explicitly called
by kvm-user itself because of some error returned from the kernel
module. I didn't investigate further what the reason could be as I
though someone else on this list must have tried this before.

Any help would be appreciated.

Ron
PS. I am trying this on an intel T2500 in a Dell D820 with VT enabled in
the BIOS

This is due to a problem kvm has in processing real mode code on intel 
processors.  If you can disable the lilo splashscreen, this may help.

I wouldn't now how to tackle this, the qemu window dissapears before I
can do anything.  Anyone knows a way around this ?

I will try to do an install without kvm and then use the resulting image
with kvm disabled. It is slow to install ubuntu this way though ...

That's the way to proceed at present.  Once you have it installed, you 
can edit lilo.conf and remove the splashscreen, then rerun lilo.
