Memory page fault handling for network interface devices in a virtualized environment

A system comprising:

• a memory;
• a processing device operatively coupled to the memory, the processing device to:
• receive, at a network interface device, an incoming packet from a network;
• select a first buffer from a plurality of buffers associated with a receiving queue of the network interface device;
• attempt to store the incoming packet at the first buffer of the plurality of buffers;
• and
• responsive to receiving a notification that attempting to store the incoming packet at the first buffer encountered a page fault:
• assign the first buffer to a wait queue of the network interface device;
• and
• store the incoming packet at a second buffer of the plurality of buffers associated with the receiving queue.

A non-transitory computer-readable media storing instructions that, when executed, cause a processing device to:

• receive, at a network interface device, an incoming packet from a network;
• select a first buffer from a plurality of buffers associated with a receiving queue of the network interface device;
• attempt to store the incoming packet at the first buffer of the plurality of buffers;
• and
• responsive to receiving a notification that attempting to store the incoming packet at the first buffer encountered a page fault:
• assign the first buffer to a wait queue of the network interface device;
• and
• store the incoming packet at a second buffer of the plurality of buffers associated with the receiving queue.
