Management and provisioning of virtual machines

A system comprising:

• one or more processors,
• a first cluster configuration of a first cluster, wherein
• an n-ary tree comprises a first leaf level and a second leaf level,
• the first leaf level comprises at least a root node of the first cluster,
• the second leaf level comprises a first plurality of potential nodes (second leaf nodes) of the first cluster,
• the first plurality of second leaf nodes are operable to host at least one virtual machine (VM), and
• the first cluster configuration comprises configuration information for one or more nodes of the first plurality of second leaf nodes, wherein
• each node of the one or more nodes generates configuration information corresponding to the each second leaf node;
• a VM configuration, wherein
• the VM configuration comprises one or more requirements that are necessary for hosting the VM;
• a comparison module, wherein
• the comparison module is configured to compare the configuration information corresponding to the each second leaf node with the VM configuration, wherein
• the each second leaf node is configured to perform a comparison of the VM configuration with the configuration information corresponding to itself,
• the comparison determines whether the each second leaf node is capable of satisfying the one or more requirements that are necessary for hosting the VM,
• the each second leaf node is configured to transmit a result of its respective comparison to the root node, and
• the result is one of a set of such results, and
• the comparison module is configured to be executed using the one or more processors;
• and
• a provisioning module configured to provision the VM to be hosted at one of the second leaf nodes, wherein
• the provisioning is based, at least in part, on the set of such results.

A computer program product comprising:

• a plurality of instructions, comprising
• a first set of instructions, executable on a computer system, configured to
• access a virtual machine (VM) configuration of a virtual machine, wherein
• the VM is to be hosted by a host node, and
• the VM configuration comprises one or more requirements that are necessary for hosting the VM,
• a second set of instructions, executable on the computer system, configured to
• access a first cluster configuration of a first cluster, wherein
• an n-ary tree comprises a first leaf level and a second leaf level,
• the first leaf level comprises at least a root node of the first cluster,
• the second leaf level comprises a first plurality of potential nodes (second leaf nodes) of the first cluster,
• the first plurality of second leaf nodes are configured to host at least one VM, and
• the first cluster configuration comprises configuration information for one or more nodes of the first plurality of second leaf nodes, wherein
• each second leaf node of the one or more second leaf nodes generates configuration information corresponding to the each second leaf node, and
• a third set of instructions, executable on the computer system, configured to compare the configuration information corresponding to the each second leaf node with the VM configuration, wherein
• the each second leaf node is configured to perform a comparison of the VM configuration with the configuration information corresponding to itself,
• the comparison determines whether the each second leaf node is capable of satisfying the one or more requirements that are necessary for hosting the VM,
• the each second leaf node is configured to transmit a result of its respective comparison to the root node, and
• the result is one of a set of such results;
• a fourth set of instructions, executable on the computer system, configured to provision the VM to be hosted at one of the second leaf nodes, wherein
• the VM is provisioned, at least in part, based upon the set of such results;
• and
• a non-transitory storage media, wherein the instructions are encoded in the non-transitory storage media.
