Abstract: Techniques are provided for provisioning network resources for virtual machines. At a first switch device, a configuration request message is received from a virtual switch to provision virtual network segmentation resources for a virtual machine managed by the virtual switch. The first switch device provisions the virtual network segmentation resources for the virtual machine. The first switch devices sends to a second switch device a first synchronization message that includes information describing the virtual network segmentation resources. The second switch device is a peer of the first switch device. The first switch device also sends to the second switch device a second synchronization message that includes state information indicating that the first switch device is in an active state for servicing the virtual machine and that the second switch device is to be placed in a dormant state for servicing the virtual machine.
