Abstract
Systems and methods for memory management for virtual machines. An example method may include receiving, by a hypervisor running on a host computer system, a request that no topology change notifications be delivered to a virtual machine managed by the hypervisor. The method may include then install a packet filter on a virtual network interface controller (vNIC) associated with the virtual machine. Responsive to receiving, by the packet filter, a topology change notification packet, the method may include dropping the topology change notification packet.
