architecture allows additional functionality to be easily added. Incorporating the plugin in CloudStack will allow the community to participate in improving the features available with Hyper-V. The plugin uses a Director Connect Agent architecture described here: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Progress Add ability to pass kvp data via the key cloudstack-vm-userdata Rearrange code to make it clearer what .NET objects are being used. Test failures are easier to deal with if test key is not deleted. Acquire management/pod ip for control ip when VR deploys in HyperV Fixed deletion on VM's on hyperv host when mgmt server gets restarted due to HA Implementation for attach iso command. Attaches an iso to a given vm.
