VM's in virtualbox do not start when using bridged adapter. They do when NAT is selected. This is because the system is running whith sysctl kern.elf64.allow_wx=0. So either kern.elf64.allow_wx needs to be set at 1, or the feature of the problematic executable /usr/local/lib/virtualbox/VirtualBoxVM should be set with elfctl -e +wxneeded. Is it possible to add an option in the port for this?
