Abstract: Rolling maintenance involves partitioning the compute nodes of a host platform into multiple maintenance domains (MDs), and patching those MDs in a rolling fashion. Techniques are described herein for establishing the VM-to-compute-node placement in an “MD-aware” manner. Specifically, the VM-to-compute-node placement takes into account the MD-to-compute-node mapping, supports constraints and goals related to achieving the required levels of availability during rolling maintenance, and for any given customer, avoids having maintenance events (and corresponding notifications) at excessive frequencies.
