I recently downloaded the b44 domU image from Sun, and am trying to start it up on my AMD64 machine running Ubuntu Feisty (linux) with xen. xm info on the host: ------------------------------------------------------------- host : flagon release : 2.6.19-4-generic-amd64 version : #2 SMP Thu Apr 5 05:57:13 UTC 2007 machine : x86_64 nr_cpus : 1 nr_nodes : 1 sockets_per_node : 1 cores_per_socket : 1 threads_per_core : 1 cpu_mhz : 1808 hw_caps : 078bfbff:e3d3fbff:00000000:00000010:00000000:00000001:00000001 total_memory : 1023 free_memory : 144 xen_major : 3 xen_minor : 0 xen_extra : .3-0 xen_caps : xen-3.0-x86_64 xen_pagesize : 4096 platform_params : virt_start=0xffff800000000000 xen_changeset : unavailable cc_compiler : gcc version 4.1.2 (Ubuntu 4.1.2-0ubuntu4) cc_compile_by : buildd cc_compile_domain : buildd cc_compile_date : Sat Mar 24 16:04:46 UTC 2007 xend_config_format : 2 ------------------------------------------------------------- When I start up the 64bit domU, I get the following: ------------------------------------------------------------- Using config file "solaris-b44-64.py".

I''m loathe to downgrade the xen host as I''m already using it for several linux domU machines. Is there a newer OpenSolaris domU image that will soon be made available? Thanks :) Gavin
