[libvirt] [PATCH 00/24] qemu: refactor node name detection
by Peter Krempa 03 Aug '17

03 Aug '17

Since query-blockstats provides full hierarchy of node names without any doubtful matching algorithm, use it to make the node name detector reliable. Unfortunately some of the changes are ugly when viewed as a diff since they delete and rewrite chunks of code.

[libvirt] [PATCH v3 0/2] Allow saving VM state to pipe
by Chen Hanxiao 03 Aug '17

03 Aug '17

This series introduce flag VIR_DOMAIN_SAVE_DIRECT to enable command 'save' to write to PIPE. This will write QEMU_SAVE_MAGIC directly. Base upon patches from Roy Keene <rkeene(a)knightpoint.com> with some fixes. Change from original patch: 1) Check whether the specified path is a PIPE. 2) Rebase on upstream. 3) Add doc for virsh command v3: add doc/news.xml rebase on upstream v2-resend: rebase on upstream v2: rename VIR_DOMAIN_SAVE_PIPE to VIR_DOMAIN_SAVE_DIRECT remove S_ISFIFO check Chen Hanxiao (2): qemu: Allow qemuDomainSaveMemory saving VM state to a pipe virsh: introduce flage --direct for save command docs/news.xml | 9 +++++++ include/libvirt/libvirt-domain.h | 1 + src/qemu/qemu_driver.c | 54 ++++++++++++++++++++++++++-------------- tools/virsh-domain.c | 6 +++++ tools/virsh.pod | 5 +++- 5 files changed, 56 insertions(+), 19 deletions(-) -- 2.7.4

[libvirt] [PATCH] driver: conditionalize use of dlopen functions & use mingw-dlfcn
by Daniel P. Berrange 02 Aug '17

Not every platform is guaranteed to have dlopen/dlsym, so we should conditionalize its use.

[libvirt] Adding switchdev NIC capability to nodedev
by Edan David 02 Aug '17

02 Aug '17

Hi, We want to add functionality to Libvirt that will allow querying the interface for the availability of switchdev mode (Offloading NIC capability) The switchdev mode was introduced in kernel 4.8, the iproute2-devlink command to retrieve the swtichdev NIC feature Command example: devlink dev eswitch show pci/0000:03:00.0 This feature is needed for Openstack so we can do a scheduling decision if the NIC is in Hardware Offload (switchdev) or regular SR-IOV (legacy) mode. And select the appropriate hypervisors with the requested capability see [1]. We also Opened Bugzilla for this [1] A patch for the feature will be submitted shortly.
