[Xen-devel] Error: Kernel image does not exist: /usr/lib/xen/boot/hvmloader

["Anand Gupta" <xen.mails@xxxxxxxxx>]

I have installed xen 3.0.4 from http://xenbits.xensource.com/xen-3.0.4-testing.hg. Now when i want to setup winxp as a domu on this server. The server is a Intel Core 2 Duo with 4GB RAM.

I took the xmexample.hvm as an example for the config. Here is the edited version.

#   "preserve",       meaning that no clean-up is done until the domain is
#                     manually destroyed (using xm destroy, for example); or

Now when i run "xm create xm1", it gives me the following error:

Using config file "./xm1".
Error: Kernel image does not exist: /usr/lib/xen/boot/hvmloader

I checked in the /usr/lib/xen/boot directory and it seems to be empty. Can anyone please tell me how to get this hvmloader ??

Thanks.
