[libvirt] [PATCH 0/8] Second take on slirp-helper & dbus-vmstate

[marcandre.lureau at redhat.com]

From: Marc-André Lureau <marcandre.lureau at redhat.com>

Hi,

The series "[libvirt] [PATCH v2 00/23] Use a slirp helper process" has
been merged and partially reverted. Meanwhile, qemu dbus-vmstate
design has been changed and merged upstream.

This new series fixes the slirp-helper support. The significant change
is that dbus-vmstate now requires a bus (instead of the earlier
peer-to-peer connection). The current series doesn't attempt to
enforce strict policies on the bus. As long as you can connect to the
bus, you can send/receive from/to anyone. A follow-up series should
implement the recommendations from
https://qemu.readthedocs.io/en/latest/interop/dbus.html#security.

The libslirp-rs slirp-helper hasn't yet received an official release.
For testing, you may:
$ cargo install --features=all --git https://gitlab.freedesktop.org/slirp/libslirp-rs

The resulting binary should be ~/.cargo/bin/slirp-helper, so qemu.conf
slirp_helper location should be adjusted. With that in place, a VM
with user networking (slirp) should now start with the helper process.

thanks

Marc-André Lureau (8):
  qemu: remove dbus-vmstate code
  qemu-conf: add configurable dbus-daemon location
  qemu-conf: add dbusStateDir
  qemu: add a DBus daemon helper unit
  domain: save/restore the state of dbus-daemon running
  qemu: prepare and stop the dbus daemon
  qemu: add dbus-vmstate helper migration support
  qemu-slirp: register helper for migration
