[libvirt] [PATCH 0/2] Rework RPC message buffer
by Michal Privoznik 14 May '12

14 May '12

This patch set tries to fix corner cases where libvirt runs on huge system, e.g. 4K CPU monster. In these cases, capabilities XML is enormously big, as we are transferring info about each singe CPU core (to which NUMA node it belongs, etc.). This XML is bigger than our RPC limit, therefore users cannot get it as it is dropped on server, leaving them with inability to connect. Therefore we need to increase those limits (whole RPC message and RPC string). However, simple lifting up will work, but increase mem usage. Therefore I've reworked RPC buffer handling: changed it from 'statically' to dynamically allocated. So in most cases - when small messages are sent - this will even decrease our memory consumption. Leaving us flexible for corner cases described above. On the other hand, I realize we've had our history with RPC breakage. So I think I'll require more than 1 ACK before pushing. What's your opinion?

[libvirt] Release of libvirt-0.9.12
by Daniel Veillard 14 May '12

14 May '12

So I made the release, it is now available on the FTP server (the rpms are slowly being uploaded too): ftp://libvirt.org/libvirt/ This is mainly a stabilization release, with a lot of bugs fixes, and portability cleanups. There is still many improvements but relatively few new features as such (the new parallels driver being postponed to the actual release of the hypervisor). I would like to raise the attention to Dan patch set to implement ACL support to the API, a very needed feature which would bring us very close to what I would hope for a 1.0.0 release: https://www.redhat.com/archives/libvir-list/2012-May/msg00090.html Let's try to bring this in for the next release !

[libvirt] [PATCH 0/6] Improve security driver support for LXC
by Daniel P. Berrange 14 May '12

14 May '12

This series aims to improve the SELinux security driver support for LXC. First it allows the SELinux driver to load different configuration for LXC, vs SELinux. Second it makes the LXC code use the security drivers for figuring out mount options. The code was originally written by Dan Walsh, but split into a 6 part patch series & made to follow coding standards by myself.

We could probably add a config param > to allow readonly/shared leases to be skipped by the sanlock plugin. Thanks for clarification. I've attached an updated patch which adds such a config param. It works but I can't test live-migration at the moment. But as far as I understood it shouldn't be a problem.
