Re: [Xen-users] Problem booting Xen DomU images under Ubuntu Jaun ty (Dom0 working nicely)

[Nicholas W <4407@xxxxxxxx>]

Hi Guido,
 Thanks for your reply.

I have tried the following:

kernel = "/workarea/xen/kernels/vmlinuz"
memory = 1024
name = "ubuntu"
vif = [ '' ]
dhcp = "dhcp"
disk = ['tap:aio:/workarea/xen/images/ubuntu.img,hda1,w',
        'tap:aio:/workarea/xen/images/swapubuntu.img,hda2,w']
root = "/dev/hda1 ro"

And I get the same sort of result. I have also tried using phy (like
in your example) instead of tap:aio
and I then get a different error:

Error: Device 769 (vbd) could not be connected.
/workarea/xen/images/ubuntu.img is not a block device.

Although the file does exist.

Hope you (or the list) can help.

Thanks again,
Regards,
Nicholas
