[libvirt PATCH v2 0/9] Second take on slirp-helper & dbus-vmstate
From: Marc-André Lureau <marcandre.lureau(a)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
