[libvirt] [Libvirt][QEMU][HLFS]How to test HLFS driver for Libvirt
by harryxiyou 29 Jan '13

29 Jan '13

Hi Morita and other developers, I have programed HLFS(HDFS based Log-structured FileSystem) driver for Libvirt according to Morita's patch(commit 036ad5052b43fe9f0d197e89fd16715950408e1d) for Libvirt, which my patch is not for Libvirt latest version but the version of Morita's patch time.I have called back my git tree to commit 036ad5052b43fe9f0d197e89fd16715950408e1d, then i develop this patch. My patch is now available at http://cloudxy.googlecode.com/svn/branches/hlfs/person/harry/hlfs/hlfs_driv… Therefore, i am not clear about how to test it. How could i know whether it works well for libvirt&QEMU? Could Morita (Or other developers) give me some suggestions? Thanks in advance ;-) -- Thanks Harry Wei

[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(-)
