Hi

I just upgraded from virtual box 1.6.2 to virtual box 1.6.4 and my network stopped working...

during installation i was told i would have to recreate interfaces, and so I did...

host: windows XP SP2

machine name: pc-sas
workgroup: workgroup

host ipconfig:

Code: Select all

The VirtualBox TAP adapter appears disconnected...

When I start the virtual box the TAP adaptar appears like this

Code: Select all

Adaptador Ethernet Interface Anfitrión VirtualBox 1          :

guest ipconfig

Code: Select all

        Puerta de enlace predeterminada   :

machine name: devel
workgroup: workgroup

from guest i can only ping the hosts tap adapter (ping 169.254.155.213) and from host I can ping the guest (ping 169.254.34.97)

i'm using host interface networking because I implemented file sharing between the host and the guest, and it was working fine...

the gust network is configured like this in virtualbox:

(I'm translating form spanish!)

Code: Select all

X enable network adapter

Adapter Type: PCNet-FAST III (Am79C973)
Conect to: Interface Anfitrión (host interface)
Interface name: Iterface Anfitrión VirtualBox1
Nombre de red (disabled)
Mac address: 080027E90996 (the same it had  before)

X cable connected

Host interfaces:
Interface Anfitrión VirtualBox 1

from the guest. i can access file resource on \\pc-sas with no problem..

so the thing is with internet... I cannot ping any external address, though.

when i first opened the virtual machine after upgrading, i was told that Interface Anfitrión VirtualBox 1 no longer existed, so I had to recreate it...

but now it broke and i don't know how to fix it

any ideas???

saludos

Read more about networking. Start with wikipedia and the APIPA article. You need to set the proper IP address to the TAP adapter. Read the VirtualBox FAQ and Manual to know how to set up Host Interfaces properly.

Best advise for this, and I don't mean it to be rude, is to go to a library or use Google and get yourself well informed of computer networking. If you don't know what you're dealing with and ask a question that has an obvious answer, don't be suprised to get a harsh response.

well, thanks for the advice

that's exactly what i was doing, meanwhile

alli was missing was to add (once again) the TAP adapter to the bridge

from networks connections, i selected the "Interface Anfitrión VirtualBox 1" and the "Conexión de área local - Athertos L2 FAST... ), right click, and added them to the bridge...

that was all

(yes, I know, just like it said in the manual...

)

thanks a lot...
