RE: [Xen-devel] Unable to bring up SMP DomUs on x86_64 Xen

[David F Barrera <dfbp@xxxxxxxxxx>]

On the SLES 9 SP2 system, I do see the stop_this_cpu.. message (my
original response was from an FC4 based system):

(XEN) (file=traps.c, line=968) Non-priv domain attempted
RDMSR(00000000c0000100,00000045,ffffffffff5fd000).
(XEN) (file=traps.c, line=968) Non-priv domain attempted
RDMSR(00000000c0000101,00000000,00000000).
(XEN) (file=traps.c, line=968) Non-priv domain attempted
RDMSR(00000000c0000102,803c7b80,ffffffff).
stop_this_cpu disable_local_APIC
