I don't know if I'm off base but have you added appropriate code to
linux? specifically arch/powerpc/platforms/xen/hcall.c ?
An existing hypercall, viz #36, do_domctl, provides several
commands to access guest domains.
For example, XEN_DOMCTL_getmemlist and XEN_DOMCTL_max_mem. Thought
I would add another to
copy the htab, XEN_DOMCTL_gethtab. So I think no modification is
needed to hcall.c
Sadly, there is:
Some architectures require that the linux kernel has knowledge of
all hcalls, and PPc is one of them
you will notice in:
there is a huge switch statement for all the domctl OPs.
If your case is not in the switch then you are subject to:
printk(KERN_ERR "%s: unknown domctl cmd %d\n", __func__,
and hence your ENOSYS
BTW: This message may not reach your dom0 console, you can either see
it by running the dmesg command --or-- add "debug" to your dom0
kernel options. Adding "sysrq=1" may be may also be a good thing
since init scripts usually disable sysrq.
