I've tested the series, and here is the first issue:
  CC      hw/9pfs/xen-9p-backend.o
  LINK    i386-softmmu/qemu-system-i386
/usr/bin/ld: ../hw/xen/xen-legacy-backend.o: in function `xen_be_register_common':
xen-legacy-backend.c:(.text+0x1cb6): undefined reference to `xen_9pfs_ops'

The `struct xen_9pfs_ops` is in "xen-9p-backend", so it's built, but
link time still fails.

Building QEMU with --disable-virtfs works. (Same as commenting out the
line that uses xen_9pfs_ops in xen-legacy-backend.) Part of the other
options I have for configure: --enable-xen --target-list=i386-softmmu
--disable-user --cpu=x86_64


I did also other build tests and one without --target-list, and that
fails, but not because of xen:
$ ./configure --enable-xen
...
$ make
