Re: [Xen-devel] Domain asking for its own destruction

["M.A. Williamson" <maw48@xxxxxxxxx>]

Indeed it is - XenoLinux does this when it shuts down.

The domain in question does a SCHED_OP_exit scheduler operation using a 
hypercall and Xen destroys the domain.
For an example of this being done in XenoLinux see HYPERVISOR_exit() in 
source/include/asm-xeno/hypervisor.h - this function is called by 
machine_restart(), machine_halt() and machine_poweroff() in 
source/arch/xeno/kernel/process.c, when the virtual machine is shut down.
On the Xen side of things, the hypercall is demuxed (in 
source/xen/arch/i386/entry.S), resulting in a call to do_sched_op() (in 
source/xen/common/schedule.c), which in turn calls kill_domain(), which 
results in various functions being called which do the business of killing 
the current domain.
HTH.
