Abstract
A method and system for supporting Wake-on-LAN technology in a virtualized environment is described. An improved virtual switch comprises a listener, which receives a power-on message on behalf of virtual machines, extracts addresses of the virtual machines to be powered on, which are embedded in the power-on message, compares the extracted addresses with addresses of the virtual machines stored in a database, and selectively powers on those virtual machines for which the extracted and stored addresses match.

A method for supporting Wake-on-LAN (WOL) for selectively powering on a virtual machine, having no network connectivity, to a local area network (LAN), the method comprising:
- employing at least one processor for:
- (a1) introducing a proxy module into the LAN, acting as a proxy for the virtual machine, the virtual machine being managed by a virtual machine manager;
- (b1) configuring the proxy module, comprising identifying an assigned unique address of the virtual machine;
- (c1) receiving, at the proxy module, a power-on message in the LAN, the power-on message including a unique address of the virtual machine;
- (d1) sending, by the proxy module, a command to the virtual machine manager to power on the virtual machine provided the assigned unique address matches with the unique address in the power-on message.
A system for supporting Wake-on-LAN (WOL) for selectively powering on a virtual machine, having no network connectivity, to a local area network (LAN), the system comprising:
- a processor;
- a memory device having computer readable instructions stored thereon for execution by the processor, causing the processor to:
- (a1) form a proxy module in the LAN, acting as a proxy for the virtual machine, the virtual machine being managed by a virtual machine manager;
- (b1) configure the proxy module to identify an assigned unique address of the virtual machine;
- (c1) receive, at the proxy module, a power-on message in the LAN, the power-on message including a unique address of the virtual machine;
- (d1) send, by the proxy module, a command to the virtual machine manager to power on the virtual machine provided the assigned unique address matches with the unique address in the power-on message.

- a memory device having computer readable instructions stored thereon for execution by the processor, causing the processor to form:
- a proxy module in the LAN, acting as a proxy for the virtual machine, the virtual machine being managed by a virtual machine manager;
- and
- the proxy module being configured to:
- identify an assigned unique address of the virtual machine;
- receive a power-on message in the LAN, the power-on message including a unique address of the virtual machine;
- and
- send a command to the virtual machine manager to power on the virtual machine provided the assigned unique address matches with the unique address in the power-on message.
