[libvirt PATCH 0/9] Support libvirt-managed QEMU domain <interface> backed by a passt process
by Laine Stump
passt (https://passt.top) provides a method for connecting a guest to
the larger network without requiring any elevated privileges. This set
of patches allows libvirt/QEMU users to easily configure a QEMU domain to
use passt for the backend of any emulated network interface.
More details are in the individual patches, but the short explanation is that
you will use:
<interface type='user'>
<backend type='passt'>
...
to select the passt backend. (We decided to do it this way since the
concept is so similar to slirp, which was the original "type='user'")
The following caveats currently apply:
1) passt support requires "-netdev stream" in QEMU, which is only
available starting with qemu-7.2.0. So if you want to test these
patches out, you need the latest upstream release of QEMU.
2) SELinux must be set to "permissive". This is of course
temporary. As I understand it, the remedy to this is a new SELinux
profile for the passt binary, which is outside the control of
libvirt and so not something that can be addressed in this patchset
(or any other patch to libvirt).
3) Although there is a a new option for QEMU's -netdev that will tell
QEMU to attempt to reconnect to a new incarnation of the same
socket if passt unexpectedly exits, and a new QEMU event that will
be put into QEMU to inform libvirt that the passt process has
exited (so that it can start a new, identical passt process), I
think this hasn't been pushed upstream yet (??), and I haven't
implemented any support for it here. So, if the passt process
unexpectedly exits, the guest will be without networking. However,
Stefano (passt author) is emphatic that passt will never
unexpectedly exit :-)
passt has *many* other options that libvirt could support, but the
small subset here are the things that seem most useful (and/or were
specifically requested by prospective users of passt). It is always
easier to add more stuff in the future than to remove "mistakes", so I
tried to no go overboard.
Laine Stump (9):
conf: rename virDomainNetBackend* to virDomainNetDriver*
conf: move anonymous backend struct from virDomainNetDef into its own
struct
conf: put interface <backend> parsing/formatting separate functions
conf: add passt XML additions to schema
conf: parse/format passt-related XML additions
qemu: new capability QEMU_CAPS_NETDEV_STREAM

[PATCH V7 00/12] spec: Decompose the daemon subpackage
by Jim Fehlig
This is V7 of
https://listman.redhat.com/archives/libvir-list/2023-January/236586.html
The end goal is to remove the libvirt-dameon dependency on the various
libvirt-daemon-driver-foo subpackages, allowing installation of a
modular daemon configuration without the traditional monolithic libvirtd.
Changes from V6:
* Revert to including virtlockd and lockd plugin in the hypervisor subpackages
* Add NEWS entry
Jim Fehlig (12):
spec: Move virtlockd to a new subpackage libvirt-daemon-lock
spec: Move virtlogd to a new subpackage libvirt-daemon-log
spec: Move virtproxyd to a new subpackage libvirt-daemon-proxy
spec: Move lockd plugin to a new subpackage
spec: Rename the libvirt-lock-sanlock subpackage
spec: Move common files and dependencies to libvirt-daemon-common
spec: Add module-init-tools dependency to nodedev and lxc drivers
spec: Add numad dependency to qemu and lxc drivers
spec: Remove libvirt-daemon dependency from drivers
spec: Remove libvirt-daemon dependency from hypervisor subpackages
kbase: Update rpm-deployment.rst with new subpackages

[PATCH v1] qemu: block: fix error when blockcopy target is librbd encrypted
by Or Ozeri
Encryption secrets are considered a format dependency, even
when being used by the storage node itself, as in the case of
using encryption engine=librbd.
Currently, the storage node is created (blockdev-add) before
creating the format dependencies (including encryption secrets).
As a result, when trying to perform a blockcopy when the target
disk uses librbd encryption, an error of this form is returned:
"error: internal error: unable to execute QEMU command 'blockdev-add': No secret with id 'libvirt-5-format-encryption-secret0'"
To overcome this error, we change the order of commands so that
format dependencies are created BEFORE creating the storage node.

[libvirt PATCH] ci: integration: Set an expiration on logs artifacts
by Erik Skultety
The default expiry time is 30 days. Since the RPM artifacts coming from
the previous pipeline stages are set to expire in 1 day we can set the
failed integration job log artifacts to the same value. The sentiment
here is that if an integration job legitimately failed (i.e. not with
an infrastructure failure) unless it was fixed in the meantime it will
fail the next day with the scheduled pipeline again, meaning, that even
if the older log artifacts are removed, they'll be immediately
replaced with fresh ones.

If you look at:
- https://gitlab.com/libvirt/libvirt/-/jobs/3563902921
- https://gitlab.com/libvirt/libvirt/-/jobs/3557946738
you can clearly see that the artifacts are still taking up (although small)
some GitLab storage space which is unnecessary since anyone interested in
debugging would opt into getting the latest ones anyway.

[PATCH v2] qemu: add append mode config for serial file
by Oleg Vasilev
Serial log file contains lots of useful information for debugging
configuration problems. It makes sense to preserve the log in between
restarts, so that one can later figure out what was going on. Before
that, we could do that on a per-domain basis, now we can configure it
once for all domains.
