Ticket #5085 (closed defect: duplicate)
Ubuntu 9.04 GUEST looses network connectivity on a Windows XP HOST after changing the HOST network connection (ETH->WLAN/3G)
|Reported by:||mawadre||Owned by:|
My VirtualBox 3.0.6 r52128 (german) is installed on a Toshiba A600 Laptop with Windows XP SP3. The computer has ethernet, WIFI/WLAN and 3G network connectors. The installed Ubuntu 9.04 Desktop guest runs fine with full network connectivity via NAT through the host's connection. But when I change the connection type on the host (e.g. ethernet -> WIFI or 3G -> ethernet) then the Ubuntu 9.04 guest looses its network connectivity. I did run wireshark on the hosts network device "SUN (Microsoft Packet Scheduler)" which apppears to be a NAT device or something else installed by VirtualBox. The only data I can see on this device after lost connectivity are lots of MDNS messages targeting 126.96.36.199 or NBNS messages targeting 188.8.131.52.
So it seams that some data is traveling from the guest Linux to the host VirtualBox network connector but nothing else.
Restart of any of the network connectors didn't change anything (Linux eth1, Windows ethernet, wlan, 3G, SUN (Microsoft Packet Scheduler)
Thanks for any help.
