This is supposed to be used in conjunction with Xen's
new hypercall interface for emualted MSI injection.

Hmm... This patch is just part of GSoC project Virtio on Xen. AFAICS,
this is not so urgent.
I would prefer a cleaner way. A standalone function that doesn't
belong to any QEMU subsystem annoys me. And the hooking looks ugly.
Thanks for your patch, I think we can wait for a better design and
cleaner solution for both Xen and KVM.

Implement a simple Xen APIC module and use it to deliver MSI/MSIX for
Xen HVM guests.

Hi, QEMU folks
I know that I might have a bad title for this post, but I just don't
have better idea for the title.
I'm developing virtio support for Xen pv guest, hoping to reuse the
virtio infrastructure in qemu, i.e. I'm planning to use qemu as
"virtio backend" for Xen pv. And qemu can be run

Bug resend.
This bug was reported about one month ago. QEMU fails to start with
Xen unstable. I found that it has not been fix with latest Xen
unstable. BIOS is Seabios (with Xen patch).

Hi all
This idea is to modify QEMU's Makefiles, plus implementing some stubs to
make it possible to tailor QEMU to a smaller binary.
The current setup for Xen on X86 is to build i386-softmmu, and uses this
single binary for two purposes:
1. serves as device emulator for HVM guest.
2. serves as PV

Those are only useful when building QEMU with HVM support.
We need to expose CONFIG_XEN_I386 to source code so we modify configure
and i386/x86_64-softmmu.mak.

Also extract a QMP function from xen-all.c and xen-stub.c to

Finally rename xen-all.c to xen-hvm.c, as those functions are only
useful to HVM guest.

-lpixman-1. However I'm not quite sure if this is the right fix, hence
the RFC tag.
Normally QEMU is built with c++ compiler which happens to link in libm
(at least this is the case with g++), so building QEMU statically
normally just works and nobody notices this issue.

# Background
To configure virtfs, there is two methods in QEMU command line:
1. Use -fsdev and -device virtio-9p-pci,XXX directives
2. Use -virtfs directive
The second method is actually shorthand for the first method. It
constructs fsdev and device options behind the scene. In the end,
there wi

And make v9fs_pack static function. Now we only need to export
v9fs_{,un}marshal to device.

Wei Liu (3):
fsdev: 9p-marshal: introduce V9fsBlob
9pfs: use V9fsBlob to transmit xattr
9pfs: introduce V9fsVirtioState
fsdev/9p-iov-marshal.c | 30
Introduce a concept of blob. It will be used to pack / unpack xattr
value.
With this change there is no need to expose v9fs_pack to device code
anymore.

The deleted file only contained V9fsConf which wasn't virtio specific.
Merge that to the general header of 9pfs.
Fixed header inclusions as I went along.
