[Xen-users] trixbox through hvm woes

[Steven Noels <stevenn@xxxxxxxxxxxxxxxx>]

Hi all,

since Google and archive searches weren't particularly helpful,  
please allow me to post my call for help here.
I'm running Xen 3.0.3-0 using Ubuntu feisty as DomO:
Linux calimero 2.6.19-4-server #2 SMP Thu Apr 5 06:07:34 UTC 2007 i686

This is a remote and headless server. I've installed a Debian etch  
DomU client into it just fine using xen-tools. I even found my way  
around ifrename to make sure that my client network devices aren't  
renamed anymore.
Using the standard Trixbox ISO install image, I would like to install  
a full-virtualized Trixbox/CentOS image. My CPU has VT extensions as  
indicated by xm dmesg.
My problem is I can't attach to the boot terminal to track the  
Trixbox install process. Here's my xm dmesg output:
(XEN) (GUEST: 20) Start BIOS ...
(XEN) (GUEST: 20) Starting emulated 16-bit real-mode: ip=F000:FFF0

(XEN) (GUEST: 20) Booting from CD-Rom...

xm list output after xm create:

intranet.outernet                          2      512     1 -b----     
523.5
However xm top shows 100% CPU usage in the asterisk/trixbox domU:

asterisk.outernet -----r         93  100.0     537808   12.8      
546000      13.0     1    1        0        0    2
       0        0        0    0

Here's my qemu output:

root@calimero:~# cat /var/log/xen/qemu-dm.7249.log
domid: 21
qemu: the number of cpus is 1
shared page at pfn:1ffff, mfn: 15a35
buffered io page at pfn:1fffd, mfn: 15a37
char device redirected to /dev/pts/2
False I/O request ... in-service already: 0, pvalid: 0, port: 0,  
data: 0, count: 0, size: 0
My main problem is I can't attach to the boot process. I've tried  
VNC, but the network setup is a bit convoluted and I'm unsure how to  
set this up. Besides, I'm not sure whether my Xen config is correct  
anyway:

kernel = '/usr/lib/xen-ioemu-3.0/boot/hvmloader'
builder='hvm'
memory  = '512'
root    = '/dev/sda1 ro'
disk    = [ 'phy:calimero-volgroup-1/asterisk.outernet- 
disk,sda1,w','file:/root/trixbox-2.2.iso,hdc:cdrom,r' ]
name    = 'asterisk.outernet'
vif  = [ 'type=ioemu,bridge=xenbr0,ip=192.168.123.13,mac=00:16:3E: 
05:03:01' ]
cdrom='/root/trixbox-2.2.iso'
boot='d'
device_model='/usr/lib/xen-ioemu-3.0/bin/qemu-dm'
sdl=0
vnc=1
stdvga=0
serial='pty'
ne2000=0
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'

Could someone validate I'm at least heading in the right direction?

Thanks,

</Steven>
