This patch shows the usage message of the commands.

Error: option --xxx not recognized
Usage: xm block-list <Domain> [--long]
List virtual block devices for a domain.

Sometimes PV domain with vfb doesn't boot up. /sbin/kudzu is stuck.
After investigation, I've found that the evtchn for console is not
bound at all.
Normal sequence of evtchn initialization in qemu-dm for xenpv is:
1) watch xenstore backpath (/local/domain/0/backend/console/<domid>/0)
2) read console info (/local/domain/<domid>/console/{type, ring-ref,
port..=
})
3) bind the evtchn to the port.
But in some case, xend writes to the backpath before the console info
is prepared, and never write to the backpath again. So the qemu-dm
fails at 2) and never reach to 3).
When this happens, manually xenstore-write command on Domain-0
resumes the guest.

When graphics card is assigned to a guest as a secondary VGA,
without gfx_passthru and emulated VGA is the primary VGA,
hvmloader misreads gfx_passthru is specified if VGA device is
found after the emulated VGA.
This patch fix this issue. If emulated VGA is found, hvmloader
preserves it and loads vgabios of the emulated VGA.

Make build.c dependency on ssdt_{pm,tpm}.h explicit, else they can be
built in the wrong order.
Also, improve naming of target DSDT structures, and specify -p option
to iasl so that all generated files for a given target have
target-unique names, hence build can proceed safely in parallel.

Previously, xc_dom_alloc_segment would go ahead even if the segment
we're trying to create is too big for the domain's RAM (or the
requested addr is out of range). It would pass invalid parameters to
xc_dom_seg_to_ptr giving undefined behaviour.
Fixing xc_dom_seg_to_ptr to fail is not sufficient because we want to
provide a comprehensible explanation to the caller - which may
ultimately be the user.
In particular, with this change attempting "xl create" with a ramdisk
image bigger than the guest's specified RAM will provide a useful
error message mentioning the ramdisk.

Previously, passing a valid pfn but an overly large count to
xc_dom_pfn_to_ptr, and functions which call it, would run off the end
of the pfn array giving undefined behaviour.
It is tempting to change this check to an assert, as no callers should
be providing invalid parameters here. But this is probably best not
done while frozen for 4.0.
