Hello. I'm a long time, but occasional VirtualBox user. VBox has always worked fine for me, but now it's "featuring" a problem I never experienced before. It's possible I upgraded it, upgraded base OS, changed hardware in the meantime... as I said my use is saltuary, so I really can't remember. In any case, VMs with bridged network start fine and work properly. However, when I shutdown/kill/stop/pause/snapshot/etc... a VM, the network hangs as a whole (even for the host). I have to: > # ifconfig re0 down > # ifconfig re0 up > # dhclient re0 in order to make it start again (before restarting any deamon that might have died meanwhile). I tried seeing if this is a known issue, but could fine nothing.
