But frankly it's not worth chasing this. Any large HVM-capable system is going to support 64-bit operation, and therefore the right thing to do is install the x86_64 hypervisor. Personally I consider the i386 hypervisor obsolescent. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
