RE: [Xen-users] can't boot from cdrom

Sorry that line is meant to have hdc instead of hdb beside the
ioemu:cdrom part... at least that is how i tested it and have it
working.

Hi,

The cdrom= option never really works, your best bet is to change the
"disk" line to read.

disk =
['file:/path/to/harddrive.img,ioemu:hda,w','file:/path/to/cdrom.img,ioem
u:cdrom:hdb,r']

then change "boot" to read.

boot ='dc'


That is if you have the CD image on the hard drive, this would probably
be the best way to do it.
If you need to copy it, just do a dd like "dd if=/dev/cdrom
of=/path/to/cdrom.img" .

Remember that the /path/to stuff is just temporary for the terms of this
help, change it to where you are keeping your images.. like
/media/sda6/usr/xenimgs/ 

Let me know if this helps.

Tait

Hi All,

Following is my winxp hvm config:

kernel = "/usr/lib/xen/boot/hvmloader"
builder = 'hvm'
memory = 192
name = "winxp"
vcpus = 2
disk = [ 'file:/media/sda6/usr/xenimgs/winxp.img,ioemu:hda,w' ]
device_model = '/usr/lib/xen/bin/qemu-dm.debug'
cdrom='/dev/hda'
sdl=1
boot='d'

and following is the boot message:
...
Booting from CD-Rom...
CDROM boot failure code : 0002
Boot from CD-Rom failed: could not read the boot disk
FATAL: No bootable device.

I have checked /dev/hda , it does exist , any idea ?

Thank you very much
yushang
