A method and system for acquiring a quiesceing set of information associated with a virtual machine. A virtual machine is cloned. The cloned virtual machine has an associated persistent storage device. The state of the persistent storage device is transformed into a quiesced state of the cloned virtual machine by utilizing a shut-down process. The shut-down process is executed on the cloned virtual machine to quiesce the cloned virtual machine and the quiesceing set of information of the cloned virtual machine is automatically reduced to information stored on the persistent storage device.

Method and system for acquiring a quiesceing set of information associated with a virtual machine

A method for detecting malicious code within a first virtual machine comprising creating a snapshot of the first virtual machine and transferring the snapshot to a second machine. A scan operation is run on the snapshot using resources of the second machine. In response to detecting malicious code during the scan operation, action is taken at the first virtual machine to address the detection of the malicious code. Thus, the action in response to detecting the malicious code may include placing the first virtual machine in quarantine.

Offloading operations to a replicate virtual machine

A method and system for offloading a software application intended to be run on a first virtual machine onto a second virtual machine. An original virtual machine is created. A periodic and/or computing resource-intensive application is supposed to be run on the original virtual machine. However, doing so may detrimentally impact the operation of the original virtual machine by consuming valuable computing resources. A replicated virtual machine which is basically a copy of the original virtual machine is created and ported over to a different host computer system. The periodic and/or computing-intensive application is now run on the replicated virtual machine instead of the original virtual machine. This leaves the original virtual machine free to continue its normal operations unaffected.

In a virtualization computer system, a method and system that does not exclusively allocate I/O devices, for example, storage and networking devices, to a commodity operating system (COS) when mainly used for booting the virtualization system. Those I/O devices needed by the COS are accessed via virtual machine kernel drivers, thereby giving the COS the benefits of operation derived from features in the virtual machine kernel that is provided for these I/O devices.

Method and system for providing device drivers in a virtualization system

A process of providing access to data associated with a virtual machine running on a host computer system to an offload server is implemented to improve the performance of the host computer system. Once the offload computer system knows how and where to access the data associated with that of the virtual machine, operations can be offloaded from the host computer system and performed by the offload server. Backup operations can be offloaded onto the server. The server can run backup software and directly access the data associated with the virtual machine, thereby freeing the hardware resources of the host computer to handle normal applications running on the virtual machine.

Accessing virtual data storage units to offload operations from a computer system hosting a virtual machine to an offload server

A system and a method dynamically adjusts the quality of service guarantees for virtual servers based upon the resource demands experienced by the virtual servers. Virtual server resource denials are monitored to determine if a virtual server is overloaded based upon the resource denials. Virtual server resources are modified dynamically to respond to the changing resource requirements of each virtual server. Occasionally, a physical host housing a virtual server may not have additional resources to allocate to a virtual server requiring increased resources. In this instance, a virtual server hosted by the overloaded physical host is transferred to another physical host with sufficient resources.
