I wrote this yesterday without any response so far: https://forums.freebsd.org/threads/poor-performance-with-virtualbox-ose.53722/ Short story. My "pretty" fast FreeBSD server (host) runs Virtualbox guests (Linux/CentOS) very slowly. Much slower than I anticipated. I've had Linux on that box before with Virtualbox without the same slowness. Where should I begin to look? And by slow, I mean /slow/. I have a PXE boot system where I can boot and install via kickstart a CentOS system in just about 4 min on a Windows machine with VirtualBox. On my FreeBSD host it takes about 10-15min. Network is slow, but disk seems to be OK. If I put some load on the guest, the guest locks up and I loose network connection to it, while the console (from VirtualBox GUI) is not responding (but the GUI for VirtualBox is working properly) Help, please!
