    Description

      There are a couple of recurring VirtualBox issues that are most likely a matter of VM configuration. These issues include

      • Missing "host-only" adapter. VirtualBox recently introduced a new NAT layer, which might provide outgoing access and host-guest access at the same time.
      • Loss of network connectivity during roaming. Also connected to the NAT layer. VMs should not directly use host services (e.g. DNS server).
      • Time skew inside the virtual machine.
      • Mounting of NFS shared folders with vagrant. Some issues due to Linux firewalls. Also not preserved on /vagrant mount point during reboot.
      • 3D graphics acceleration.
      • Benchmark of different virtual I/O sub systems. Perhaps there is better performance with, e.g., virtio.
