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?

Checking it out...looks like Xen is pretty screwed on Opteron machines
at the moment (at least on my dual Opteron workstation). There seems to
be some timer issue...takes forever fro the machine to boot up.
Oh..AMD does not have an option for the NX bit...the cpu always can
understand it.

Probably getting stuck in a page-fault loop. We also have observed this
probnlem but haven;t narrowed down what changeset causes the problem.
We think it's one from sometime last week though (before the weekend).
If you can give info on the last changeset that works for you, that
would be very useful.

This is the first time I have tried domU's for x86_64, but I'll jump
back a week and do a binary search.

I was able to boot domU on 3 EMT64T machines, SLES 9 SP2 based.

I'll take sometime tonight & go through the changesets & see if I can
narrow it down further.

Try to remove the network stuff. The warnings are harmless. I've got
domU working at least yesterday, seeing the warnings.

Please could you lookup the symbols for the eip and maybe the first

They're all innocuous, except the one in the middle which is a
grant-reference unmap request failing. Not sure what's going on there.

That is incorrect. AMD's 64-bit processors use NXE, bit 11, in EFER (MSR
0xC0000080) to determine if NX is "in use" or not.
However, I'm not aware of any way to disable the ability to set this bit
in the MSR, if that's what you mean by "AMD does not have an option for
the NX bit".

You apparently miss understand this. Intel CPUs have an option in the
bios where if bit 11 is set it has no idea what to do with it. Where
as on AMD 64-bit CPUs if bit 11 is set then it always does. My big
complaint is why Intel made this possible in the first place.

Wow I just read this ...don't write emails really early in the
morning :-)
Ok the problem is that in Xen x86-64 the NX bit is set on memory pages
and your Intel EM64T CPU cannot understand this....xen go boom! So there
is an option in the bios for Intel EM64T CPUs that is called "disable
execute bit" (at least on IBM machines). This name is a bit
misleading...it enables the NX feature on the CPU (does not activate
it). So what this option does is allow the activation of NX bit
enforcement on the CPU as well as allow the CPU to understand the NX bit
set on memory pages. Where as on AMD K8 CPUs always have the ability to
have the NX bit feature there used and understands the bit set on memory
pages.
Much better..

Looks like we are stuck in xen_l1_entry_update():

u.ptr = virt_to_machine(ptr);
u.val = pte_val_ma(val);

Do you not get a couple of lines from Xen imediately preceeding the
crash? Might be worth a debug=y build.

I'll make sure debug=y is on. I also noticed I did not limit this
system to 3g (it has 4g). I recall this being a problem recently. I'll
limit my memory and try again.
the xen output:
(XEN) (file=traps.c, line=880) Non-priv domain attempted
RDMSR(00000000c0000080.
(XEN) DOM2: (file=mm.c, line=461) Non-privileged attempt to map I/O
space 000000
(XEN) Domain 2 (vcpu#0) crashed on cpu#3:
(XEN) CPU: 3
BTW, has anyone tried compiling xenU x86_64 kernels with debug on? I
error out on, hmm, can't recall the file right now, maybe entry.S. More
info on that shortly.

Yes, I tried that a long while back. There's some mismatch in the CFI
macros (ISTR it was actually head.S). Should be trivial to fixup.
