[libvirt] [jenkins-ci PATCH 0/3] Enable building of the VZ driver on CentOS 7
by Daniel P. Berrangé 11 Jul '19

11 Jul '19

The VZ driver in libvirt periodically gets broken by refactoring in libvirt. This is not noticed either before or after merge because none of our CI tests nor common developer build hosts includ the deps needed for the VZ driver. The OpenVZ project, however, does provide builds of the required packages for RHEL-7. We can use these packages in our CentOS 7 CI VMs to enable build testing of the VZ driver. This closes the only hole we have in driver build coverage for CI. Daniel P.

[libvirt] [jenkins-ci PATCH] guests: Make Java symlink creation conditional

[libvirt] [PATCH 00/10] qemu: remove json fields from domain and monitor objects
by Ján Tomko 11 Jul '19

11 Jul '19

Applies on top of Peter's removal of commandline parsing https://www.redhat.com/archives/libvir-list/2019-June/msg00405.html After removal of qemuProcessAttach there is no codepath that could possibly set monJSON to false (not that libvirt would be able to much with such domain), so we can finish cleaning it up.

[libvirt] [PATCH 00/23] Enable proper use of systemd socket activation with libvirtd
by Daniel P. Berrangé 11 Jul '19

11 Jul '19

The libvirtd daemon has some support for systemd socket activation from: commit 27a7081c2968ca0d7fbd590629b5a5303851f4a3 Author: Martin Kletzander <mkletzan(a)redhat.com> Date: Tue Jul 15 15:28:53 2014 +0200 daemon: support passing FDs from the calling process First FD is the RW unix socket to listen on, second one (if applicable) is the RO unix socket. This was originally intended for use by the libvirt client when doing auto-spawning of libvirtd, but we later deleted that client side code in commit be78814ae07f092d9c4e71fd82dd1947aba2f029 Author: Michal Privoznik <mprivozn(a)redhat.com> Date: Thu Apr 2 14:41:17 2015 +0200 virNetSocketNewConnectUNIX: Use flocks when spawning a daemon We never added systemd socket units before as we need libvirtd to start on boot to perform autostart. It was recently pointed out by Lennart that these two features are not mutually exclusive though. Libvirtd can be set to start on boot, and also have socket unit files. The idea is that we start libvirtd on boot, perform autostart, and then libvirtd can exit if nothing is running. The socket unit files are then there to start it again when a mgmt app connects. This series implements that strategy. In doing so the current socket activation support was rewritten to be more flexible, able to cope with the admin socket and the TCP/TLS sockets, all passed in any order. NB, I don't believe I have got the RPM upgrade procedure right yet. As there are alot of scenario to test for upgrades, I need more validation of that. The series is long enough now though, that it would benefit from code review already This socket activation is also going to be important when we split out the daemons, as we will use the same libvirtd codebase for these new daemons, simply compiled with different options.

[libvirt] [PATCH 0/5] Implement qemu-ga 'guest-get-users'
by Jonathon Jongsma 11 Jul '19

11 Jul '19

This set of patches adds new API and an implementation for getting the active users for a domain via the guest agent. There is only an implementation for the qemu driver. I've implemented the remote protocol and added support in virsh (new command 'guestusers'). A lot of the implementation was modelled on the implementation of guest-get-fsinfo, which also returns an array of info structures. Since this is my first time adding API or dealing with libvirt RPC stuff, I anticipate several rounds of the series. This series addresses https://bugzilla.redhat.com/show_bug.cgi?id=1704761 Jonathon Jongsma (5): lib: add API to query info about logged-in users remote: implement remote protocol for virDomainGetGuestUsers virsh: add command 'guestusers' implementing VirDomainGetGuestUsers qemu_agent: add helper for getting guest users qemu: implement virDomainGetGuestUsers include/libvirt/libvirt-domain.h | 18 ++++ src/driver-hypervisor.h | 6 ++ src/libvirt-domain.c | 62 ++++++++++++++ src/libvirt_public.syms | 5 ++ src/qemu/qemu_agent.c | 92 ++++++++++++++++++++ src/qemu/qemu_agent.h | 2 + src/qemu/qemu_driver.c | 38 +++++++++ src/remote/remote_daemon_dispatch.c | 89 ++++++++++++++++++++ src/remote/remote_driver.c | 82 +++++++++++++++++- src/remote/remote_protocol.x | 26 +++++- src/remote_protocol-structs | 17 ++++ tests/qemuagenttest.c | 125 ++++++++++++++++++++++++++++ tools/virsh-domain.c | 76 +++++++++++++++++ tools/virsh.pod | 4 + 14 files changed, 640 insertions(+), 2 deletions(-) -- 2.20.1
