Thanks - that's exactly what I needed to reproduce here.

Not working (git master)

$ ./qemu-system-ppc64 -m 128 -prom-env 'auto-boot?=false' -incoming
'exec:cat</tmp/foo.save'
hflags: 0x9000000000000000
msr: 0x9000000000000000

Working (patch reverted)

$ ./qemu-system-ppc64 -m 128 -prom-env 'auto-boot?=false' -incoming
'exec:cat</tmp/foo.save'
hflags: 0x8000000000000000
msr: 0x8000000000000000

Looks like the bit being set differently in the MSR is MSR_SHV
(hypervisor state).


ATB,

Mark.
