Abstract:
Implementations are described for guest controlled virtual device packet filtering. A method of the disclosure includes receiving, at a guest operating system (OS) of a virtual machine executed by a processing device of a host machine, a notification of a host configuration change from a hypervisor of the host machine, the host configuration change affecting routing of networking packets corresponding to the virtual machine over a network, implementing, by the guest OS, configuration changes to a guest OS environment, the configuration changes corresponding to the host configuration change, and in response to implementing the configuration changes, notifying, by the virtual machine, the hypervisor that network packet filtering of the networking packets can be disabled.
