This is due to the change over to use the realmode emulator in
place of vmxassist. I presume that you get the error even when
starting just one guest (i.e. not 32 at a time)?
The instruction that''s failed seems to be a "pop %es"; not
sure
why unfortunately - the code path seems to have no error option
save where the realmode memory ops are missing, or when
dealing with CS or SS (which have constraints).
Can you add some tracing to xen/arch/x86/x86_emulate.c
to see which [if any] of lines 2049, 2053 or 2056 are failing?
cheers,
S.

Does the error message really look the same whether booting Windows or Linux HVM? It¹s unlikely we have the same real-mode emulation problem on both. Or do you boot them both through the same bootloader (e.g., GRUB)? It would be useful if you could confirm the same problem when you build Xen without modified max_phys_cpus, and gave the HVM guest a normal¹ amount of memory (e.g., 1 gigabyte). And any differences between errors for the Windows and Linux guests do matter, if there are any. -- Keir On 11/2/08 20:07, "Carb, Brian A" <Brian.Carb@unisys.com> wrote:> Running Xen Unstable changeset 16998 (pulled 20080208) on Unisys ES7000/one > 64x 256gb with SLE10SP1 x64. > > Trying to start an hvm guest.
