[libvirt] [PATCH 0/2] qemu: migration: show disks stats for nbd migration
by Nikolay Shirokovskiy 21 Dec '16

21 Dec '16

Current migration stats will show something like [1] when in the process of mirroring of non shared disks. This gives very little info on the migration progress. Likewise completed stats miss disks mirroring info. This patch provides disks stats in the said phase like in [2] so user can now understand what's going on. However data stats miss memory stats, so data total and remaining will change when memory migration starts. AFAIU disks stats were available before the nbd based migration becomes the default. So this patch returns disks stats back at some level. Patch 1 is just a little cleanup. Removed code uses qemuMigrationFetchJobStatus so the patch 1 helps analysis of the patch 2.

[libvirt] connecting to qemu domain monitor socket outside of libvirt/virsh
by Jason Miesionczek 21 Dec '16

21 Dec '16

Hi, So I see that when i have a qemu vm running, that i created via libvirt, there is a socket here: /var/lib/libvirt/qemu/domain-<name>/monitor.sock I am trying to connect to this socket via cli or a completely separate C/C++ application to be able to control the VM, but I can't seem to get it to work. Does anyone know if/how this is possible? I've tried 'nc', 'socat', and based on the qemu libvirt code, 'socket'/'connect', but nothing seems to work. Also, is it possible through libvirt, when creating a qemu VM, one can specify to enable the QMP socket? Thanks in advance, Jason

[libvirt] [PATCH v2 0/1] storage: vstorage support
by Olga Krishtal 21 Dec '16

21 Dec '16

The patch supports pool and volume managment using Vistuozzo Storage (vstorage) as a backend. To define pool use: virsh -c qemu+unix:///system pool-define-as --name VZ --type vstorage --source-name vz7-vzstorage --target /vzstorage_pool The resulting XML: <pool type='vstorage'> <name>VZ</name> <uuid>5f45665b-66fa-4b18-84d1-248774cff3a1</uuid> <capacity unit='bytes'>107374182400</capacity> <allocation unit='bytes'>1441144832</allocation> <available unit='bytes'>105933037568</available> <source> <name>vz7-vzstorage</name> </source> <target> <path>/vzstorage_pool</path> <permissions> <mode>0700</mode> <owner>0</owner> <group>0</group> </permissions> </target> </pool> For the vstorage pool the only obligatory parameter, which stores cluster name, is --source-name. v2: - maximum code reusage - fixed name issue - we use vstorage - simplified findPoolSources Olga Krishtal (1): storage: vz storage pool support configure.ac | 28 ++++++++++ docs/schemas/storagepool.rng | 13 +++++ include/libvirt/libvirt-storage.h | 1 + src/conf/storage_conf.c | 16 +++++- src/conf/storage_conf.h | 4 +- src/storage/storage_backend.c | 3 + src/storage/storage_backend_fs.c | 114 ++++++++++++++++++++++++++++++++++++-- src/storage/storage_backend_fs.h | 3 + src/storage/storage_driver.c | 2 + tools/virsh-pool.c | 2 + tools/virsh.c | 3 + 11 files changed, 181 insertions(+), 8 deletions(-) -- 1.8.3.1

[libvirt] [RFC] add option to bring new qemu binary/pending conf changes on reboot
by Nikolay Shirokovskiy 21 Dec '16

21 Dec '16

Hi, all. I'm trying to reword the long pending RFC [1]. We interested in next usecase. Administrator update qemu binary/make domain configuration changes that transparent to the guest. This changes are not applied until domain shutdown/started by domain user. Sometimes user just reboots domain and these changes as they transparent can be applied too and this is a good opportunity to apply changes. For example new qemu binary have some optimizations and administrator would like to use these optimizations and don't want to force user to restart, waiting for user reboot is considered good enough. To support this use case we can add 'recreate' option to on_reboot/on_shutdown event. [1] https://www.redhat.com/archives/libvir-list/2016-June/msg02259.html

[libvirt] New libvirt maven releasing and issue with detach volume
by Rohit Yadav 21 Dec '16

21 Dec '16

Hi, >From [1][2] I found the emails on your ML and owner of libvirt-java. I see several changes since last libvirt-java release 0.5.1, can we have a release please if those changes are critical for libvirt users? I've found and reported an issue with detach volume/disk that fails to remove the xml/vbd from the VM's xml, I'm not sure if it's related to the libvirt 0.5.1 library (that we used for testing): http://markmail.org/thread/djzxozewjfhsyimh Any help or comment on this would be great. Thanks. [1] http://libvirt.org/git/?p=libvirt-java.git;a=summary [2] https://libvirt.org/contact.html#email Regards.

Hi all, With the new website, it still has the News page: https://libvirt.org/news.html But there doesn't seem to be a link to it from anywhere. Is that a bug? + Justin
