Can't seem to fully boot a domU on either EM64T or Opteron with x86_64 xen-unstable. Both systems' report this from xen:

(XEN) (file=traps.c, line=872) Non-priv domain attempted WRMSR(00000000c0000100. (XEN) (file=traps.c, line=872) Non-priv domain attempted WRMSR(00000000c0000102. (XEN) (file=traps.c, line=880) Non-priv domain attempted RDMSR(00000000c0000080.

They boot partially, ending with:

xen_mem: Initialising balloon driver.
Grant table initialized
IA32 emulation $Id: sys_ia32.c,v 1.32 2002/03/24 13:02:28 ak Exp $
audit: initializing netlink socket (disabled)
audit(1124251914.348:0): initialized
VFS: Disk quotas dquot_6.5.1
Dquot-cache hash table entries: 512 (order 0, 4096 bytes)

This is with the default kernel configs xen-unstable provides. NX is enabled on the EM64T. I could not find a similar BIOS option for Opteron. Even through they are "stuck", cpu time for these domains increments steadily. Any ideas?
