[Xen-devel] Error while booting Windows from image file

["Stefan Mitov" <mitov@xxxxxx>]

Hi people,

i'm using the latest version of Xen 3.2 with a debian -4.0r1. there are no 
problems by compiling and installing of xen. installing a windows vm from 
physical cd-rom is also no problem. but when a want to install windows from a 
image file(winxp.iso), i get the following message :


ata0master: QEMU HARDDISK .......
ata0slave: unknown device
ata1master: QEMU CD-ROM ATAPI-4 CD-Rom/DVD-Rom
ata1slave: unknown device

Booting from CD-Rom ....
CDROM boot failure code : 0004
Boot from CD-Rom failed: could not read the boot disk
FATAL: No bootable devices 


My config file is :
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 2048
name = "WinXP"
vcpus=2
disk = [ 'file:/var/lib/xen/images/winxpdisk.img, ioemu:hda,w', 
'file:/winimages/winxp.iso,ioemu:hdc:cdrom,r' ]
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm
boot="d"
vnc=1


what do you think, where can be the error? i tried many combinations and looked 
the examples in the user manual, but booting from image file doesn't work. 
And one more thing. When i installed a virtual machine, how can i change the 
boot device for the next boot operations of it, so that the installed machine 
every time boots from the virtual disk, and not from the cd-rom?

Kindly Regards

Stefan
