[Pkg-xen-devel] Bug#520641: Cannot create HVM domain

[Richard Kettlewell]

Package: xen-utils-3.2-1
Version: 3.2.1-2

If I try to create an HVM domain I get the following error message:

araminta:~# xm create -c heceptor.cfg
Using config file "/etc/xen/heceptor.cfg".
Error: Creating domain failed: name=heceptor

xend-log has a Python backtrace in it:

None of this tells me what, if anything, I've done wrong (i.e. if the 
error is entirely mine then the bug is that the error reporting is 
totally useless).

The config is as follows:

# grep '^[^#]' /etc/xen/heceptor.cfg
kernel = "/usr/lib/xen-3.2-1/boot/hvmloader"
builder='hvm'
memory = 192
name = 'heceptor'
vif         = [ 'type=ioemu, ip=172.17.207.9,mac=00:16:3E:5B:18:B4, 
model=ne2k_pci' ]
disk = [ 'file:/xen/domains/heceptor/hda.img,ioemu:hda,w', 
'file:/var/www/software/freebsd/7.1-RELEASE-i386-dvd1.iso,ioemu:hdc:cdrom,r' 
]
boot = 'dc'
device_model = 'qemu-dm'
sdl=0
vnc=1
vncpasswd=''
stdvga=0
serial='pty'

PV domains run fine on the same system.
