[libvirt] lxc: setsid() usage
by Richard Weinberger 23 Jun '15

23 Jun '15

Hi! Why is libvirt-lxc issuing a setsid() in lxcContainerSetupFDs()? To me it seems like a hack to have a controlling TTY if PID 1 is /bin/bash. If one runs a sysv init style distro (like Debian) in libvirt-lxc the setsid() has a major downside, when getty spawns a login shell on /dev/tty1 it cannot become the controlling tty. Hence, if one presses ctrl-c in such a session, the container will reboot. Interestingly it does not happen when a systemd distro is used. Maybe because systemd completely closes and reopens the TTY? Thanks, //richard

[libvirt] [PATCH v2] nodeinfo: fix to parse present cpus rather than possible cpus
by Kothapally Madhu Pavan 23 Jun '15

23 Jun '15

Currently we are parsing all the possible cpus to get the nodeinfo. This fix will perform a check for present cpus before parsing.

[libvirt] [PATCH 0/3] yajl cleanups
by Eric Blake 23 Jun '15

23 Jun '15

Fixes 'make check' on RHEL 6, which I recently broke, then adds further improvements to the JSON parser. I'm tempted to push patch 1/3 as a build-breaker, but since the other two need review, I'll hold off and we can do all three as a series.

[libvirt] bisected: Unable to get index for interface...
by Thomas Voegtle 23 Jun '15

23 Jun '15

Hi, On my own build linux system without systemd, I have following problem, when I try to start a qemu VM, libvirtd.log says: 2015-06-23 08:29:25.498+0000: 889: error : virNetDevGetIndex:842 : Unable to get index for interface vm0.0: No such device 2015-06-23 08:29:25.551+0000: 886: error : virNetDevGetIndex:842 : Unable to get index for interface vm0.0: No such device 2015-06-23 08:29:25.611+0000: 888: error : virNetDevGetIndex:842 : Unable to get index for interface vm0.0: No such device ... virsh dumpxml vm: ... <interface type='ethernet'> <mac address='52:54:00:cd:15:51'/> <target dev='vm0.0'/> <model type='virtio'/> <boot order='3'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x0f' function='0x0'/> </interface> ... I had no problems with 1.2.12, so I started a git bisect and I came down to this: # first bad commit: [4bbe1029f2fb6cd1c102794951a944c62fdbd0e6] qemu: fix ifindex array reported to systemd When I revert that commit on top of 1.2.13.1, problem is gone. I tried today's version (d10a5f58c75), problem is still in there. Hope this is useful to you? Thomas

[libvirt] [PATCH] admin: Fix mingw build by reordering includes
by Martin Kletzander 23 Jun '15

23 Jun '15

By trying to lead the way of clean includes, I sorted the lines alphabetically and that is a problem for mingw builds with gnulib. As 'configmake.h' defines DATADIR and 'datatypes.h' transitively includes 'winsock.h' that uses 'DATADIR' as a name for a struct, it's enough to reorder those. Even though this might be worked around in gnulib later on, this fixes the build for now.
