Ok. I get an error while trying to boot a stubdomain HVM.

Boot messages are below and the error messages in them are highlighted in RED.

HVM configuration file contents are also mentioned below after the boot messages.



Using config file "./sample.hvm-stubdomain".

Stubdomain Configuration contents are

Any clues?

Subject: [Xen-users] How to create a HVM stubdomain




I went through stubdomain README to create a HVM stubdomain and the README has mentioned about install.iso

Where can I find this installable HVM image?
