...coming stream data (stream is a way that libvirt uses to transfer binary data). Problem is that instead of returning NULL to our malloc()-s once the limit is reached, kernel decides to kill us. For anybody with libvirt insight: virNetClientIOHandleInput() -> virNetClientCallDispatch() -> virNetClientCallDispatchStream() -> virNetClientStreamQueuePacket(). The obvious fix would be to stop processing incoming packets if stream has "too much" data cached (define "too much"). But this may lead to unresponsive client event loop - if the client doesn't pull data from incoming stream fa...

Hi all: I am using the libvirt version that comes with Ubuntu 18.04.3 LTS. I have written a script that backs up my virtual machines every night. I want to limit the amount of memory that this backup operation consumes, mainly to prevent page cache thrashing. I have described the Linux page cache thrashing issue in detail here:
