Commit b13485493733585cce3044d209063bf37a774ece in branch refs/heads/master from Toshiaki Hatano [ https://git-wip-us.apache.org/repos/asf?p=cloudstack.git;h=b134854 ] CLOUDSTACK-3431: KVM: cloudstack-plugin-hypervisor-kvm with BridgeVifDriver doesn't cleanup vNet due to multiple reasons - Move vnetBridge clean up function from LibvirtComputingResource to BridgeVifDriver -- since only BridgeVifDriver have to handle this event - LibvirtComputingResource now properly call VifDriver.unplug() when it receives UnPlugCommand - Remove not working and no longer used method getVnet(String) from VirtualMachineName - Remove not working and no longer used method getVnet() from StopCommand - Remove unused constructer StopCommand(VirtualMachine, String, boolean) from StopCommand - Remove unused member vnet from StopCommand - Remove unused member _modifyVlanPath from OvsVifDriver Tested with 2 KVM hosts and confirmed it correctly manipulate vnetBridge with start, stop, migrate, plug, and unplug event Signed-off-by: Hugo Trippaers <htrippa...@schubergphilis.com> - ASF Subversion and Git Services On July 12, 2013, 4:17 a.m., Toshiaki Hatano wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
