Abstract
A method, computer program product, and computing system for establishing a connection between a virtualization device and a virtual machine infrastructure. The virtualization device may be configured to be communicatively coupled to one or more PCIe devices. A virtual machine may be executed on the virtual machine infrastructure. Control of the virtualization device may be passed through the virtual machine infrastructure to the virtual machine.
Claims19
A computer-implemented method, executed on a computing device, comprising:
- establishing, via the computing device, a connection between a virtualization device and a virtual machine infrastructure, wherein the virtualization device is configured to be communicatively coupled to one or more PCIe devices;
- executing a virtual machine on the virtual machine infrastructure;
- and
- passing control of the virtualization device through the virtual machine infrastructure to the virtual machine, wherein passing control of the virtualization device through the virtual machine infrastructure to the virtual machine includes preventing an error from the one or more PCIe devices communicatively coupled to the virtualization device from being received by the virtual machine infrastructure.
A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:
- establishing a connection between a virtualization device and a virtual machine infrastructure, wherein the virtualization device is configured to be communicatively coupled to one or more PCIe devices;
- executing a virtual machine on the virtual machine infrastructure;
- and
- passing control of the virtualization device through the virtual machine infrastructure to the virtual machine, wherein passing control of the virtualization device through the virtual machine infrastructure to the virtual machine includes preventing the one or more PCIe devices communicatively coupled to the virtualization device from being accessible to the virtual machine infrastructure.
A computing system including a processor and memory configured to perform operations comprising:
- establishing a connection between a virtualization device and a virtual machine infrastructure, wherein the virtualization device is configured to be communicatively coupled to one or more PCIe devices, wherein a number of PCIe devices communicatively coupled to the virtualization device is greater than a virtual machine infrastructure-imposed limit on a number of pass through devices associated with the virtual machine infrastructure;
- executing a virtual machine on the virtual machine infrastructure;
- and
- passing control of the virtualization device through the virtual machine infrastructure to the virtual machine.
