Re: [Xen-users] xm shutdown of HVM DomU kills it instantly
virsh shutdown <domain id> does graceful shutdown. The problem is
that xend remembers the domain id. I want to be able to use the same
domain id for the same virtual machine. I tried to flush the domain id
memory by doing a "service xend restart" but it still would resort to
incrementing the domain id number even though the previous domain id
had been shutdown.

xend doesn't send the ACPI Shutdown (which would simulate a "power button
push" event in the ACPI-aware OS) command to the QEmu monitor for the
HVM? Not sure what the exact qemu command is (can never seem to get
the 'help' command in the qemu monitor to show just one page of help
topics).
Using KVM (which uses the same or similar qemu support) you can issue a
shutdown command in the qemu monitor, or via the host, and it will show
as an acpi shutdown request in the guest OS, and it will (if ACPI support
works in the guest) do a graceful shutdown.
