    • An embodiment of the invention is directed to a method associated with a node comprising a hypervisor and guest VMs, each guest VM being managed by the hypervisor and disposed to run applications, the node being joined with other nodes to form an HA cluster. The method includes establishing an internal bidirectional communication channel between each guest VM and the hypervisor, and further includes sending commands and responses thereto through the channel, wherein respective commands manage a specified application running on the given guest VM. The messages are selectively monitored, to detect a failure condition associated with the specified application running on the given guest VM. Responsive to detecting a failure condition, action is taken to correct the failure condition, wherein the action includes sending at least one command through the internal channel from the hypervisor to the given guest VM.
    • 本发明的实施例涉及与包括管理程序和来宾VM的节点相关联的方法,每个访客VM由管理程序管理并被设置为运行应用程序,该节点与其他节点连接以形成HA群集。 该方法包括在每个来宾VM和管理程序之间建立内部双向通信信道,并且还包括通过该信道发送命令和响应,其中相应的命令管理在给定来宾VM上运行的指定应用。 有选择地监视消息,以检测与给定来宾VM上运行的指定应用程序相关联的故障状况。 响应于检测到故障状况,采取动作来纠正故障状况,其中动作包括通过内部通道从管理程序发送至少一个命令给给定的客户VM。
