[libvirt] [PATCH] Clarify the meaning of version in redirdev filters
by Ján Tomko 12 Mar '15

The version attribute in redirdev filters refers to the revision of the device, not the version of the USB protocol.

[libvirt] [PATCH v3 00/15] Drop network driver lock
by Michal Privoznik 12 Mar '15

12 Mar '15

Well, this is interesting. I've turned the virNetworkObjList into using a virHash. And even though the performance in my testing (using the very same test program as in previous versions of the patch set) increased. Without these patches, the test program took 56s to finish. With these patches (that is with virHash table) it takes 46s, which is better. But previously, with network objects stored in flat array I was able to get somewhere around 23s! I wonder what may be the cause. NB, nearly all patches in the series have been ACKed already, but since I'm switching the virNetworkObjList internals, I'm posting them again. Michal Privoznik (15): virNetworkObjListPtr: Turn list into a hash table network_conf: Make virNetworkObj actually virObject network_conf: Introduce virNetworkObjEndAPI bridge_driver: Use virNetworkObjEndAPI test_driver: Use virNetworkObjEndAPI parallels_network: Use virNetworkObjEndAPI virNetworkObjList: Derive from virObjectLockableClass network_conf: Introduce locked versions of lookup functions virNetworkObjListPtr: Make APIs self-locking virNetworkObjFindBy*: Return an reference to found object struct _virNetworkDriverState: Annotate items bridge_driver: Drop networkDriverLock() from everywhere test_driver: Drop testDriverLock() from almost everywhere parallels_network: Drop parallelsDriverLock() from everywhere. bridge_driver: Use more of networkObjFromNetwork cfg.mk | 2 - src/conf/network_conf.c | 545 +++++++++++++++++++++++------------ src/conf/network_conf.h | 13 +- src/libvirt_private.syms | 7 +- src/network/bridge_driver.c | 197 +++---------- src/network/bridge_driver_platform.h | 5 +- src/parallels/parallels_network.c | 62 +--- src/test/test_driver.c | 108 ++----- tests/networkxml2conftest.c | 4 +- tests/objectlocking.ml | 4 - 10 files changed, 441 insertions(+), 506 deletions(-) -- 2.0.5

Some Coverity patches - the first one has been showing up in my dailies for a few days... The other 5 I don't see, but that's because I don't generally build with xenapi in my Coverity environment. So for those, I'm hoping someone with that environment could check them out.

Well technically this is the pinning API's, but keeping the subject the same for continuity sake. v4: http://www.redhat.com/archives/libvir-list/2015-March/msg00262.html Specifically replacing patches 5-9 Changes over v4 - remove the virDomainGetIOThreadPin related code leaving only the virDomainPinIOThread code.

[libvirt] [PATCHv2 0/4]add support for graphics to get a IPv6 address
by Luyao Huang 11 Mar '15

https://bugzilla.redhat.com/show_bug.cgi?id=1192318 We already support add a IPv6 address to graphics listen address and xml like this: <graphics type='spice' port='5900' autoport='yes' listen='2001b8:ca2:2::1' keymap='en-us'> <listen type='address' address='2001b8:ca2:2::1'/> </graphics> However we do not support get a IPv6 address for the network. add some helpers and rework networkGetNetworkAddress to make it can get a IPv6 address when we need.
