Using Oracle stock Virtualbox current production on SL 7.1 . Guest is MS Win 7 Pro. When the physical LAN on a SL 7 host is a wired 802.3 connection using a static IP (not DHCP), the standard Virtualbox NAT works. However, when the physical SL 7 LAN is a wireless 802.11 connection using DHCP and controlled by Network Manager, the SL 7 host works, but the MS Windows guest claims there is no network with what appears to be the same Virtualbox NAT configuration. Has anyone else experienced this issue? This used to work on IA-32 SL 6, but has not been working on X86-64 SL 7. In all cases, the MS Win 7 guest is configured for IA-32.
