I installed Ubuntu 9.10 on my laptop, then installed VirtualBox 3.12 and have a guest OS > Windows XP Pro.
Everything was great for about a month, then my WindowsXP VM can't get an IP address all of a sudden. I can't recall doing anything to cause that, perhaps Ubuntu auto-updates messed something up?
I can use Virtual Box's NAT setting - that works fine, but I want XP to get its IP address form the regular LAN pool so that it appears just like a regular PC on the same subnet. I was able to achieve that by selecting "Bridged" network adapter in Vbox, using WLAN0 (my wireless NIC - the one that laptop is using for Internet). But that stopped working now. :(
Like I said.. it was working all fine, XP VM was getting an IP address from my router, but not anymore - just (Limited or NO Connectivity) in XP.
I even tried re-installing XP VM, but without any success. I don't know much about Linux networking, but suspect that something broke in that area...
Could anybody please point me the right direction, or suggest troubleshooting method?
