Hi -- 'xenpvh' doesn't appear to be a signed tag:

From https://gitlab.com/sstabellini/qemu
 * branch                    xenpvh     -> FETCH_HEAD
error: FETCH_HEAD: cannot verify a non-tag object of type commit.
Does not appear to be a signed tag

thanks

Sorry "xenpvh" was a branch name. Here is the corresponding signed tag:

Something weird has happened here -- I'm getting merge conflicts
in files in migration/ and in tests/unit/test-xbzrle.c, even though
your pullreq diffstat says it doesn't touch those files. Can you
try a rebase and resend?

thanks

Just sent as a full pull request patch series. Also here for
convenience:

I've rebased my tree at 
https://git.infradead.org/users/dwmw2/qemu.git/shortlog/refs/heads/xenfv
on top of this.

For the "phase 1" series I've been posting already, there's not a lot
of interaction. But when it comes to wiring up all the PV back ends
there were a few things to tweak, including frowning at the fact that
you moved xen_bus_init() and xen_be_init() to somewhere generic to
cover both "actual Xen" builds, while I wanted to move it to pc.c to
cover "actual Xen" and "emulated Xen" on i386. I think I'm happy with
what I did there in the final two commits.

Please could I ask you to give it a quick smoke test on Arm?
