A method, comprising:

• receiving, by a hyper-kernel on a first computing node, an indication of a stalling event caused by a requested portion of memory being inaccessible, wherein the first computing node is included in a plurality of physically interconnected computing nodes, and wherein a guest operating system is run on a virtual environment that is defined by a set of hyper-kernels running on the plurality of physically interconnected computing nodes;
• determining, at least in part by the hyper-kernel performing a query of a data structure comprising identifiers of portions of memory designated as being frequently updated, whether the requested portion of memory is designated as a frequently updated portion of memory;
• and
• handling the stalling event based at least in part on the determination of whether the requested portion of memory is designated as a frequently updated portion of memory.
