[libvirt] [PATCH] add --nocow option to vol-create and vol-clone
by Chunyan Liu 19 Dec '13

19 Dec '13

Btrfs has terrible performance when hosting VM images, even more when the guest in those VM are also using btrfs as file system. One way to mitigate this bad performance is to turn off COW attributes on VM files (since having copy on write for this kind of data is not useful). According to 'chattr' manpage, NOCOW could be set to new or empty file only on btrfs, so this patch tries to add a --nocow option to vol-create functions and vol-clone function, so that users could have a chance to set NOCOW to a new volume if that happens to create on a btrfs like file system.

[libvirt] Implementation deficiency in virInitctlSetRunLevel
by Reco 19 Dec '13

19 Dec '13

Hello, list. I was pointed here by maintainer of libvirt package in Debian, Guido Günther. For the sake of completeness, the original bug report can be viewed at this link: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=732394 To sum up the bug report, current implementation of virInitctlSetRunLevel function (src/util/virinitctl.c) lacks any sanity checks before writing to container's /dev/initctl. In the absence of such checks, libvirtd can be easily tricked to write runlevel check request to an arbitrary main hosts' file (including hosts' /run/initctl, as described in the bug report). All it takes is one symlink in place of containers' /dev/initctl. I've checked current libvirtd's git, and it seems to me that the problem is still here. Attached to this letter is a patch which tries to mitigate the issue by checking whenever container's /dev/initctl is a pipe actually. Sincerely yours, Reco PS I'm not subscribed to this list, in case of further questions please CC me.

[libvirt] python pypi package - backport older version?
by Jason Antman 19 Dec '13

19 Dec '13

Hello, First off, thanks for the wonderful project, and thanks even more for all of the excellent work on the Python bindings lately. I'm working on a small project to collect data on kvm hosts/guests via a python collector client and display the data in a web interface. It works beautifully when using my various distros' OS packages for libvirt-python, but I've hit a bit of a snag when trying to do automated testing. I'm quite happy to see libvirt-python packaged as a python package and on pypi, but the version there is 1.2.0, which requires libvirt >= 0.9.11. Unfortunately, I was planning to test my python app on travis-ci, which runs Ubuntu Precise (12.04 LTS), and the latest version of libvirt for that is 0.9.8 (package python-libvirt 0.9.8-2ubuntu17.13). If I were to submit a patch, would there be any interest in me backporting the setup.py/packaging work to an older version of the python bindings - say 0.9.8 - and getting it published on pypi? Thanks, Jason Antman CMGdigital Atlanta, GA

[libvirt] [PATCH v2] libxl: libxl_get_max_cpus returning a libxl error from 4.4 onward
by Dario Faggioli 19 Dec '13

19 Dec '13

Starting from commit 2e82c18c in Xen (will be included in Xen 4.4) both libxl_get_max_cpus() and libxl_get_max_ndoes() start returning a proper libxl error code, in case of failure. This patch fixes this in the libxl driver. Note that, although it is now basically impossible for them to return 0, that would, theoretically, still be wrong. Also, checking that the returned value is '<= 0' makes the code correct for both Xen 4.4 and Xen 4.3 (and 4.2), and that is why we go for it (rather than just '< 0').
