I am using a Windows 7 x64 laptop as my VirtualBox host. And I'd like my single-NIC Linux guest to share the wireless connection of host.
I want my guest to be a network peer of the host, so using NAT is not an option.
I tried to create a bridge connection with wireless NIC and VirtualBox host-only NIC on host. It works at start, but it fails when the laptop restores from sleep. The bridge connection loses its IP, and there is no way to regain it with DHCP, except for removing the bridge and recreating it.
