Hi
everyone,
I am running
XenEnterprise 3.1.0 (Xen v.3.0.3.0) on x86-32 hardware. I have noticed that the
hvm_hypercall_table is initialized for only 6 hypercalls (memory_op, multicall,
xen_version, event_channel_op, sched_op, and hvm_op). The hypercall_page for HVM
domain is initialized with HVM exit (VMCALL instr.) - all
stubs.
So, how do I do the
other hypercalls (beyond those 6) from HVM domain? Do I just have to use
INT 0x82 trap without using the hypercall-page (without using the HYPERVISOR_*
hypercall macros in hypercall.h)?
Why there is just
those six hypercalls implemented as HVM-hypercalls?
Thanks.
George
