Technologies for virtual machine migration

One or more machine-readable media comprising a plurality of instructions stored thereon that, in response to execution, causes a source node to:

• establish each virtual machine of a plurality of virtual machines at a corresponding tier of a plurality of quality-of-service tiers, wherein the plurality of quality-of-service tiers includes a highest tier and at least one lower tier;
• identify a set of the virtual machines of the plurality of virtual machines based on the tier associated with each virtual machine, wherein each virtual machine of the set of virtual machines has the at least one lower tier associated therewith;
• perform a pseudo-migration for each of the virtual machines of the set of virtual machines, wherein performing the pseudo migration comprises emulating a pre-copy phase of a corresponding live migration to determine a dynamic working set of the corresponding virtual machine;
• and
• select a virtual machine of the set of virtual machines for live migration based on the dynamic working set associated with each virtual machine of the set of virtual machines.

A method for managing migration of a virtual machine from a source node to a destination node, the method comprising:

• establishing, by the source node, each virtual machine of a plurality of virtual machines at a corresponding tier of a plurality of quality-of-service tiers, wherein the plurality of quality-of-service tiers includes a highest tier and at least one lower tier;
• identifying, by the source node, a set of the virtual machines of the plurality of virtual machines based on the tier associated with each virtual machine, wherein each virtual machine of the set of virtual machines has the at least one lower tier associated therewith;
• performing, by the source node, a pseudo-migration for each of the virtual machines of the set of virtual machines, wherein performing the pseudo migration comprises emulating a pre-copy phase of a corresponding live migration to determine a dynamic working set of the corresponding virtual machine;
• and
• selecting, by the source node, a virtual machine of the set of virtual machines for live migration based on the dynamic working set associated with each virtual machine of the set of virtual machines.
