Network Problem : Host-only Adapter

[Gil]

Hello!

I was running VirtualBox v3.1.0 windows version on a:

HOST : MS Windows Vista Home Premium SP2 GUEST : MS Windows XP SP3

That guest only have 1 network adapter : 'Host-only adapter'

After the new release I've decided to up-to-date my VirtualBox from v3.1.0 to the new v3.1.2. Everything went smoothy.

But now with the new version 'v3.1.2' and without any other changes except 'Guest Addictions' update, the network fails to be able to comunicate with the host and vice-versa.

I have no custom configurations at either network cards nor host's or guest's.

And further questions you can relay them to my email.

Thanks in advance.

Is your guest configured to obtain IP settings dinamically (via DHCP)? If yes(which is by default on windows systems), please make sure you have VBox DHCP server configured properly for your host-only adapter network. This can be done via "File -> Preferences -> Network" in VBox GUI. Also make sure the host-only adapter on your host is cofigured properly (i.e. having proper static IP configuration).

Let me know if you have any questions re host-only configuration.

I made some screenshots about what you said showing my current unaltered configurations.

They're at:

Hmm, ​http://gafda.no.sapo.pt/scrsht_1.png and ​http://gafda.no.sapo.pt/scrsht_3.png show different IP settings for your host-only adapter. Are you sure there were no changes to your host-only IP config in between scrsht_1.png and scrsht_3.png?

Please try specifying IP 192.168.56.1 and Net mask 255.255.255.0 in host-only adapter settings in VBox GUI (shown in scrsht_1.png) and see if it helps.

Yes, I am sure. I just split the image in two but it's in fact one single screenshot.

Specifying the IP did the trick.

At the time I reported the bug I've had :

HOST : MS Windows Vista Home Premium SP2 (32bits)

...now, under same circumstances and with : HOST : MS Windows 7 Home Premium (64 bits)

I didn't got the same problem and I've not specified any IP but it works fine.

Thanks for your help!

BTW: I believe VirtualBox works faster over Win7. (Same machine, different S.O.)
