[libvirt] [PATCH] nwfilter: drop use of awk

[libvirt] [PATCH] Fix adding ports to OVS bridges without VLAN tags
by Kyle Mestery 05 Sep '12

05 Sep '12

The introduction of the new VLAN code, along with the fix from 5e465df6be8bcb00f0b4bff831e91f4042fae272, caused the addition of OVS ports to fail with the following message: ovs-vsctl: 00002|vsctl|ERR|: missing column name This fix takes into account the VLAN arguments are optional, and correctly sets up the command line to run the "ovs-vsctl" command to add ports to the OVS bridge.

[libvirt] [PATCH] (updated) additional parameters needed for dnsmasq
by Gene Czarcinski 05 Sep '12

05 Sep '12

As I said in a previous message, dnsmasq is forwarding a number of queries upstream that should not be done. There still remains an MX query for a plain name with no domain specified that will be forwarded is dnsmasq has --domain=xxx --local=/xxx/ specified. This does not happen with no domain name and --local=// ... not a libvirt problem.

[libvirt] [PATCH 00/45 v3] Atomic APIs to list objects
by Osier Yang 04 Sep '12

04 Sep '12

v3 - v4: * Except a few patches are pushed, it's just rebasing on the top v2 - v3: * Various document fixes/improvements (Suggested by Laine and Eric) * Destroy virdomainlist.[ch], and folder all list helper funcs into its own *_conf.[ch] * Improve the helpers to get the object list. See https://www.redhat.com/archives/libvir-list/2012-July/msg01267.html * Rebased on top of commit 3df9626 by Peter and the virReportError series by Daniel. * Rebased on top of virsh split series. (I'm luck there is no change on those commands since v2). Except the already supported APIs for domain and domain snapshot, this series add the APIs for the left objects, including storage pool, storage vol, network, interface, node device, nwfilter, and secret. * Storage pool: - Support filtering the returned pool objects by active|inactive, persistent|transient, autostart|no-autostart, and pool types. - New options for virsh, --type to accept multiple pool types. * Storage vol: - Simply returns all the vol objects of a pool. * Network: - Support filtering the results using flags active|inactive, persistent|transient, autostart|no-autostart - New options for virsh. * Interface: - Support filtering the results using flags active|inactive. It's still O(n) underlying, as interface driver doesn't manage the objects itself, but using netcf lib instead. And netcf APIs don't support returning the struct yet. * Node Device: - Support filtering the results using capabilities type of the devices. - Extend --cap to accept multiple capability type. * Network Filter: - Simply returns all the objects. * Secret: - Simply returns all the objects. Osier Yang (45): list: Define new API virStorageListAllStoragePools list: Add helpers for listing storage pool objects list: Implement the RPC calls for virConnectListAllStoragePools list: Implement listAllStoragePools for storage driver list: Implement listAllStoragePools for test driver list: Add helper to convert strings separated by ', ' to array virsh: Fix the wrong doc for pool-list list: Change MATCH for common use in virsh list: Use virConnectListAllStoragePools in virsh python: Expose virStorageListAllStoragePools to python binding list: Define new API virStoragePoolListAllVolumes list: Implemente RPC calls for virStoragePoolListAllVolumes list: Implement virStoragePoolListAllVolumes for storage driver list: Implement virStoragePoolListAllVolumes for test driver list: Use virStoragePoolListAllVolumes in virsh list: Expose virStoragePoolListAllVolumes to Python binding list: Define new API virConnectListAllNetworks list: Implement RPC calls for virConnectListAllNetworks list: Add helpers to list network objects list: Implement listAllNetworks for network driver list: Implement listAllNetworks for test driver list: Use virConnectListAllNetworks in virsh list: Expose virConnectListAllNetworks to Python binding list: Define new API virConnectListAllInterfaces list: Implemente RPC calls for virConnectListAllInterfaces list: Implement listAllInterfaces list: Use virConnectListAllInterfaces in virsh list: Expose virConnectListAllInterfaces to Python binding list: Define new API virConnectListAllNodeDevices list: Implemente RPC calls for virConnectListAllNodeDevices list: Add helpers for listing node devices list: Implement listAllNodeDevices list: Expose virConnectListAllNodeDevices to Python binding virsh: Fix a bug of nodedev-list list: Use virConnectListAllNodeDevices in virsh list: Define new API virConnectListAllNWFilters list: Implement RPC calls for virConnectListAllNWFilters list: Implement listAllNWFilters list: Use virConnectListAllNWFilters in virsh list: Expose virConnectListAllNWFilters to Python binding list: Define new API virConnectListAllSecrets list: Implement RPC calls for virConnectListAllSecrets list: Implement listAllSecrets list: Use virConnectListAllSecrets in virsh list: Expose virConnectListAllSecrets to Python binding daemon/remote.c | 382 ++++++++++++++++++++++ include/libvirt/libvirt.h.in | 101 ++++++- python/generator.py | 11 +- python/libvirt-override-api.xml | 44 +++- python/libvirt-override-virConnect.py | 72 +++++ python/libvirt-override-virStoragePool.py | 11 + python/libvirt-override.c | 337 ++++++++++++++++++++ src/conf/network_conf.c | 91 ++++++ src/conf/network_conf.h | 22 ++ src/conf/node_device_conf.c | 103 ++++++ src/conf/node_device_conf.h | 16 + src/conf/storage_conf.c | 116 +++++++ src/conf/storage_conf.h | 35 ++ src/driver.h | 35 ++- src/interface/netcf_driver.c | 135 ++++++++ src/libvirt.c | 487 ++++++++++++++++++++++++++++- src/libvirt_private.syms | 4 + src/libvirt_public.syms | 7 + src/network/bridge_driver.c | 17 + src/node_device/node_device_driver.c | 15 + src/node_device/node_device_driver.h | 3 + src/node_device/node_device_hal.c | 1 + src/node_device/node_device_udev.c | 1 + src/nwfilter/nwfilter_driver.c | 56 ++++ src/remote/remote_driver.c | 449 ++++++++++++++++++++++++++ src/remote/remote_protocol.x | 80 +++++- src/remote_protocol-structs | 85 +++++ src/secret/secret_driver.c | 59 ++++- src/storage/storage_driver.c | 85 +++++ src/test/test_driver.c | 101 ++++++ tools/virsh-domain-monitor.c | 2 - tools/virsh-domain.c | 19 +- tools/virsh-interface.c | 259 +++++++++++----- tools/virsh-network.c | 351 ++++++++++++++++----- tools/virsh-nodedev.c | 302 ++++++++++++++++--- tools/virsh-nwfilter.c | 163 ++++++++-- tools/virsh-pool.c | 441 ++++++++++++++++++++------ tools/virsh-secret.c | 182 +++++++++-- tools/virsh-volume.c | 197 +++++++++--- tools/virsh.c | 56 +++- tools/virsh.pod | 51 +++- 41 files changed, 4521 insertions(+), 463 deletions(-) create mode 100644 python/libvirt-override-virStoragePool.py -- 1.7.7.3

[libvirt] [PATCH 0/2] Support for Block Device IO Limits
by Viktor Mihajlovski 04 Sep '12

04 Sep '12

Depending on the hypervisor (e.g. QEMU) it is possible to override certain properties of a block device. In Linux these are called IO limits and can be observed in the guest's sysfs under /sys/block/<dev>/queue. This patch set enables libvirt to override the logical and physical block size for QEMU guests. I wasn't expecting the 0.10.1 release *that* early, so I have added the since 0.10.1 in formatdomain.html.in :-) calling for a v2 patch. Still I wanted to collect review feedback.

[libvirt] [PATCH 0/4] Support to set disk wwn
