Abstract
A method and system for managing communication connections in a virtualization environment implemented by a cluster of host machines, each of the host machines comprises a hypervisor, at least one user virtual machine (UVM), a connection manager, and an I/O controller. The system includes a virtual disk accessible by all of the I/O controllers and comprising a plurality of storage devices. The system includes a first host machine of the host machines designated as a leader node, wherein the leader node configured to confirm a second one of the host machines is unreachable; and transmit, in response to the confirmation, an update message to other host machines in the cluster. The update message identifies the unreachable host machine and causes the other host machines to block messages from the unreachable host machine and send an acknowledgement of the update message back to the leader node.
