[SOLVED] Ubuntu Linux guest crashes on hard network traffic
Posted: 12. May 2011, 20:36
Hello,
I'm using VirtualBox under OSX to run many Linux virtual machines for development purposes.
Recently, I've observed kernel panics in virtual machines while they are generating a lot of network traffic.
For example, I have a virtual machine running a mongodb server, and another one running a java application. When I stress test the mongodb server, either the mongodb virtual machine or the java virtual machine hang. I see this when I go over 3/4 communication thread (have no idea how many connections the mongodb driver is generating, but I can see a lot of traffic, until everything stops).
In both machines I was using the Intel PRO 1000 network card. The problem disappeared when I switched both to virtua-net. Is that support broken? Or the Ubuntu driver incompatible with the emulated virtualbox card?
