Server cluster-based system and method for management and recovery of virtual servers
First Claim
1. A system for controlling virtual servers comprising:
- a plurality of virtual servers running on a cluster having multiple hardware servers, the virtual servers sharing an operating system;
each virtual server having an associated access identifier and a unique system-wide identifier;
each virtual server including an internal control procedure for control of that virtual server using the associated access identifier and the unique system-wide identifier; and
an external control interface operable outside the virtual server for control of the virtual server in response to commands sent by a remote user using the associated access identifier and the unique system-wide identifier,wherein, if a particular virtual server is non-responsive, the external control interface can be used to manage that virtual server using the associated access identifier and the unique system-wide identifier,wherein the external control interface is executed on any of the hardware servers and is available to the remote user when a particular virtual server is unresponsive, or when the internal control procedure of that virtual server is unreachable, or when services provided by the internal control procedure are unreachable.

Abstract
A system, method and computer program product for controlling virtual servers includes a plurality of virtual servers running on a host computer. An access identifier and a unique identifier can be associated with each virtual server. A control procedure(s) is within each corresponding virtual server, and can be used to control that virtual server in response to control commands. A control interface is outside the virtual servers and can be used for control of the virtual servers in response to control commands. The control command can be executable by both the control procedure(s) and the control interface, or can be executable by the control interface if the control procedure(s) is unreachable, or can be executable by the control interface if the virtual server has failed, or can be executable even if the virtual server is inaccessible. The control interface can be accessible by using multiple addresses and identifiers.

12. A method of managing virtual servers, comprising:
-
launching a plurality of virtual servers running on cluster having multiple hardware servers, the virtual servers sharing an operating system; assigning an associated access identifier and a unique system-wide identifier to each virtual server; starting, on each virtual server, an internal control procedure operable that is inside the virtual server for control of that virtual server using the associated access identifier and the unique system-wide identifier; and starting an external control interface outside the virtual server for control of the virtual server in response to commands sent by a remote user using the associated access identifier and the unique system-wide identifier, wherein, if a particular virtual server is non-responsive, the external control interface can be used to manage that virtual server using the associated access identifier and the unique system-wide identifier associated with that virtual server, and wherein the external control interface is executed on any of the hardware server of the cluster and is available to the remote user when a particular virtual server is unresponsive, or when the internal control procedure of that virtual server is unreachable, or when services provided by the internal control procedure are unreachable. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A computer program product for managing virtual servers, the computer program product comprising a non-transitory computer useable storage medium having computer program logic recorded thereon for controlling at least one processor, the computer program logic comprising code configured to execute the following steps:
-
launching a plurality of virtual servers running on a cluster having multiple hardware servers, the virtual servers sharing an operating system; assigning an associated access identifier and a unique system-wide identifier to each virtual server; starting, on each virtual server, an internal control procedure operable that is inside the virtual server for control of that virtual server using the associated access identifier and the unique system-wide identifier; and starting an external control interface outside the virtual server for control of the virtual server in response to commands sent by a remote user using the associated access identifier and the unique system-wide identifier, wherein, if a particular virtual server is non-responsive, the external control interface can be used to manage that virtual server using the associated access identifier and the unique system-wide identifier associated with that virtual server, and wherein the external control interface is executed on any of the hardware server of the cluster and is available to the remote user when a particular virtual server is unresponsive, or when the internal control procedure of that virtual server is unreachable, or when services provided by the internal control procedure are unreachable.
