[libvirt] [PATCH] LXC: create directory /dev/shm automatically
by Gao feng 29 Jan '13

29 Jan '13

Now we mount /dev as tmpfs and haven't created directory /dev/shm,so the glibc api such as shm_open/sem_open will create files under dir /dev.(since /dev is mounted as tmpfs) Through these api still useable in container,but this cause directory /dev looks a little chaos. This patch create directory /dev/shm automatically,the files created by shm_open/sem_open will stay in this directroy.

[libvirt] Candidate Release 2 of libvirt-1.0.2
by Daniel Veillard 29 Jan '13

29 Jan '13

I have just tagged the rc2 in git and pushed the associated tarball and rpms for F17 to the FTP area: ftp://libvirt.org/libvirt/ Seems to work just fine for m limited testing, but please give it a try, and let's limit commits to only bug fixes until the release. I think I will push 1.0.2 final on Wednesday morning if everything is going fine until then, thanks for any testing and feedback !

[libvirt] [PATCH v3 0/3] add pci-bridge support
by liguang 29 Jan '13

29 Jan '13

Now, it's impossible to arrange devices into multi-pci-bus, for example: <sound model='ac97'> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </sound> <video> <model type='cirrus' vram='9216' heads='1'/> <address type='pci' domain='0x0000' bus='0x1' slot='0x02' function='0x0'/> </video> libvirt will complain about "bus != 0", fortunately, qemu supports pci-to-pci bridge, if we want to use multi-pci-bus, we can define 2 pci bridge controllers, then attach 1 to the other as a subordinate pci-bus, so, 2 pci-buses appear. for example: <controller type='pci-bridge' index='0'/> <controller type='pci-bridge' index='1'> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </controller> <sound model='ac97'> <address type='pci' domain='0x0000' bus='0x01' slot='0x02' function='0x0'/> </sound> <video> <model type='cirrus' vram='9216' heads='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> src/conf/domain_conf.c | 5 ++++- src/conf/domain_conf.h | 1 + docs/schemas/domaincommon.rng | 1 + src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 70 ++++++++++++++++++++----- 6 files changed, 57 insertions(+), 23 deletions(-)

This version fixes most of coments on v1 by DanPB and Martin. The two things that are not yet done are: 1) docs and 2) support for the xend driver I will follow up with those tomorrow after I create a testbed for xen.

[libvirt] [RFC PATCH 0/n] Glue domain and storage
by Osier Yang 28 Jan '13

28 Jan '13

This is the 4th part to implement NPIV migration support [1]. Part 1: https://www.redhat.com/archives/libvir-list/2013-January/msg00859.html Part 2: (Already ACKed by Michal) https://www.redhat.com/archives/libvir-list/2013-January/msg00859.html Part 3: https://www.redhat.com/archives/libvir-list/2013-January/msg01012.html This set is based on above 3 ones. The subject "Glue domain and storage" is a bit bigger than what this series does. This set only tries to support using the storage for domain disks. And the storage might be further used by disk backing chains, or future scsi-host passthrough, etc, if the pricinple is correct. However, this can setup the basis, which can be extended for future stuffs. This introduces new XMLs to specify the disk source with storage like (See PATCH 3/n for more details): <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source type='pool'> <pool uuid|name="$var"/> <volume name|path|key='$var'/> <seclabel relabel='no'/> </source> <target dev='vdb' bus='virtio'/> </disk> And before domain starting, the source represented by storage is translated into the real underlying source. Disk of type 'network' is not supported yet. But I'd like post the patches as soon as possible to make sure I'm not on the wrong road.
