[Xen-users] Minix doesn't boot on XEN HVM but works with Qemu

[Andreas Hollmann <capjo@xxxxxxxx>]

Hi,

I tried to boot both Minix 2.0.4 and Minix 3.1.2 on a XEN HVM DomU.

In both cases the system will not boot. The last messages which appears
on the screen is

Hit a key as follows:

   1   Regular Minix 3 ...
   2   Small Minix 3 ...

I used the following configuration.

kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 128
name = "Minix"
disk = [ 'file:/root/xenconf/minix_312/minix.disk,ioemu:hda,w', 
'file:/root/xenconf/minix_312/IDE-3.1.2a.iso,ioemu:hdb:cdrom,r']
vif = [ 'type=ioemu, bridge=xenbr0' ]
device_model = '/usr/lib/xen/bin/qemu-dm'
boot='d'
sdl=1
vnc=0

With Qemu I can boot both versions of Minix without any problems.

[root@localhost minix_312]# qemu -m 128M -hda minix.disk -cdrom 
IDE-3.1.2a.iso -boot d
Could not open '/dev/kqemu' - QEMU acceleration layer not activated

I thought the HVM domain is very similar to Qemu, however many images 
that run on Qemu don't run on XEN.
I'm using Fedora 7 with the latest XEN Kernel.

Regards,
Andreas
