[libvirt] [PATCHv2 0/5] Allow to query a guest's hostname

by Guido Günther

The following patches allow to query a guest's hostname. Once we also have support to set the hostname via the domain's xml we can also print it in "virsh dominfo" by default so I left it out for now. I left the version at 0.9.14. It'd be happy to change this ot 0.10 should we settle for that one. Changes since last time: * drop patch to print hostname in "virsh list" * add remote protocoll support * Addressed Eric's style comments * openvzVEGetStringParam: Let virCommandRun do the error printing and missing error handling * Don't return empty hostnames but raise VIR_ERR_OPERATION_FAILED instead Cheers, -- Guido Guido Günther (5): Add virDomainGetHostname virsh: Add domhostname remote: Provide RPC call for domainGetHostname openvz: Add openvzVEGetStringParam openvz: Implement domainGetHostname include/libvirt/libvirt.h.in | 2 ++ src/driver.h | 6 ++++++ src/libvirt.c | 45 ++++++++++++++++++++++++++++++++++++++++++ src/libvirt_openvz.syms | 2 +- src/libvirt_public.syms | 5 +++++ src/openvz/openvz_driver.c | 42 +++++++++++++++++++++++++++++++++++++++ src/openvz/openvz_util.c | 32 ++++++++++++++++++++++++++++++ src/openvz/openvz_util.h | 1 + src/remote/remote_driver.c | 1 + src/remote/remote_protocol.x | 12 ++++++++++- src/remote_protocol-structs | 8 ++++++++ tools/virsh.c | 44 +++++++++++++++++++++++++++++++++++++++++ tools/virsh.pod | 4 ++++ 13 files changed, 202 insertions(+), 2 deletions(-) -- 1.7.10.4

[libvirt] [PATCH 00/50] Atomic APIs to list objects

by Osier Yang

Except the already supported APIs for domain and domain snapshot, this series add the APIs for all the left objects, including storage pool, storage vol, network, interface, node device, nwfilter, secret. * Storage pool: - Support filtering the returned pool objects by active|inactive, persistent|transient, autostart|no-autostart, and pool types. - New options for virsh, --type to accept multiple pool types. * Storage vol: - Simply returns all the vol objects of a pool. * Network: - Support filtering the results using flags active|inactive, persistent|transient, autostart|no-autostart - New options for virsh. * Interface: - Support filtering the results using flags active|inactive. It's still O(n) underlying, as interface driver doesn't manage the objects itself, but using netcf lib instead. And netcf APIs don't support returning the struct yet. * Node Device: - Support filtering the results using capabilities type of the devices. - Extend --cap to accept multiple capability type. * Network Filter: - Simply returns all the objects. * Secret: - Simply returns all the objects. All the commands are tested with both new libvirt with the APIs support, or old libvirt without the support. By the way, I'm wondering if should split the virsh wood, it's really big now, and still growing up. It might take a bit more time to compile if it's splitted into multiple files (split it by the command group?) though, but it's good for maintaining and eyes (I have a small screen). Any opinions?

[libvirt] Libvirt/LXC/SystemD/SELinux Hackfest at Linux Plumbers, San Diego

by Daniel P. Berrange

Hi Folks, This years Linux Plumbers Conference (LPC)[1] is taking place in San Diego in the last week of August (co-located with LinuxCon). Since there is alot of integration between libvirt / LXC / SystemD and SELinux, and many of the key developers from those projects will be at LPC, Lennart proposed we hold a hackfest at LPC on this subject To quote Lennart's blog[2]: "On 28th of August we'll have a hackfest on the topic of closer integration of libvirt, LXC, systemd and SELinux, colocated with LPC in San Diego, California. We'll have a number of key people from these projects participating, including Dan Walsh, Eric Paris, Daniel P. Berrange, Kay Sievers and myself. Topics we'll cover: making Fedora/Linux boot entirely cleanly in normal containers, teaching systemd's control tools minimal container-awareness (such as being able to list all services of all containers in one go, in addition to those running on the host system), unified journal logging across multiple containers, the systemd container interface, auditing and containers, running multiple instances from the same /usr tree, and a lot more... Who should attend? Everybody hacking on the mentioned projects who wants to help integrating them with the goal of turning them into a secure, reliable, powerful container solution for Linux. Who should not attend? If you don't hack on any of these projects, or if you are not interested in closer integration of at least two of these projects. How to register? Just show up. You get extra points however for letting us know in advance (just send us an email). Attendance is free." NB, note the date - 28th of August is the Tuesday - ie the day *before* the main LPC conference programme begins. We have space reserved in the main hotel for the hackfest on this day.
