/**
 *   This class represents a HostShare capacity allocation from a VM. The following
 *   attributes are updated with the final allocation in the Host:
 *     - topology, number of sockets, cores and threads
 *     - pci, with device address
 *     - nodes with the numa nodes configured for the VM
 *
 *    NUMA node requests are described by an attribute:
 *
 *    NUMA_NODE = [ TOTAL_CPUS=, MEMORY="...", CPUS="...", NODE_ID="...",
 *      MEMORY_NODE_ID="..." ]
 *
 *    CPUS: list of CPU IDs to pin the vCPUs in this host
 *    NODE_ID: the ID of the numa node in the host to pin this virtual node
 *    MEMORY_NODE_ID: the ID of the node to allocate memory for this virtual node
