## Abstract

Systems and methods for Virtual Machine (VM) attribution with hardware information. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include a Central Processing Unit (CPU) and a memory coupled to the CPU, the memory having program instructions stored thereon that, upon execution by the CPU, cause the IHS to: provide a management console configured to manage a plurality of hypervisors, each hypervisor configured to be executed in a different one of a plurality of physical servers distinct from the IHS, each hypervisor further configured to create and run at least one Virtual Machine (VM); identify, via the management console, a hardware capability of a given one of the plurality of physical servers; and assign the VM, by the management console, to the given physical server in response to the identification of the hardware capability.

## Claims

### Claim 1

An Information Handling System (IHS), comprising:
a Central Processing Unit (CPU); and
a memory coupled to the CPU, the memory having program instructions stored thereon that, upon execution by the CPU, cause the IHS to:
provide a management console configured to manage a plurality of hypervisors, each hypervisor configured to be executed in a different one of a plurality of physical servers distinct from the IHS, each hypervisor further configured to create and run at least one Virtual Machine (VM), wherein the VM is associated with a tag requesting a Fault Resilient Memory (FRM);
identify, via the management console, an FRM of one of the plurality of physical servers;
assign a first VM, by the management console, to a selected one of a plurality of zones in the FRM of the identified physical server; and
assign a second VM, by the management console, to the selected zone of the FRM of the identified physical server in response to a determination that the first VM and the second VM have data affinity.

### Claim 2 (depends on 1)

The IHS of claim 1, wherein the FRM is absent from at least another one of the plurality of physical servers.

### Claim 3 (depends on 1)

The IHS of claim 1, wherein the FRM is absent from all other ones of the plurality of physical servers.

### Claim 4 (depends on 1)

The IHS of claim 1, the memory having program instructions stored thereon that, upon execution by the CPU, cause the IHS to:
receive a request to migrate the first VM;
identify another one of the plurality of physical servers that has the FRM; and
transfer the first VM to the identified another physical server.

### Claim 5

A computer-implemented method, comprising:
identifying a Fault Resilient Memory (FRM) of one of a plurality of physical servers;
receiving a user request for a virtual machine (VW), wherein the request includes a tag associated with the FRM;
assigning a first VM to a selected zone of the FRM of the identified physical server in response to the identification of the FRM; and
assigning a second VM to the selected zone of the FRM of the identified physical server in response to a determination that the first VM and the second VM have data affinity.

### Claim 6 (depends on 5)

The computer-implemented method of claim 5, the memory having program instructions stored thereon that, upon execution by the CPU, cause the IHS to:
receive a user request to migrate the VM;
identify another one of the plurality of physical servers that has the FRM; and
transfer the VM to the identified another physical server.

### Claim 7 (depends on 5)

The computer-implemented method of claim 5, wherein the FRM is absent from at least another one of the plurality of physical servers.

### Claim 8 (depends on 5)

The computer-implemented method of claim 5, wherein the FRM is absent from all other ones of the plurality of physical servers.

### Claim 9 (depends on 5)

The computer-implemented method of claim 5, further comprising:
receiving a request to migrate the first VM;
identifying another one of the plurality of physical servers that has the FRM; and
transferring the first VM to the identified another physical server.

### Claim 10

A memory device having program instructions stored thereon that, upon execution by an Information Handling System (IHS ), cause the IHS to:
identify a Fault Resilient Memory (FRM)of one of a plurality of physical servers;
receive a user request for a virtual machine (VM), wherein the request includes a tag associated with the FRM;
assign a first VM to a selected zone of the FRM of the identified physical server in response to the identification of the FRM; and
assign a second VM to the selected zone of the ERM of the identified physical server in response to a determination that the first VM and the second VM have data affinity.

### Claim 11 (depends on 10)

The memory device of claim 10, wherein the FRM is absent from at least another one of the plurality of physical servers.

### Claim 12 (depends on 10)

The memory device of claim 10, wherein the FRM is absent from all other ones of the plurality of physical servers.

### Claim 13 (depends on 10)

The memory device of claim 10, wherein the program instructions, upon execution by the IHS, cause the IHS to:
receive a request to migrate the first VM;
identify another one of the plurality of physical servers that has the FRM; and
transfer the first VM to the identified another physical server.
