    I have Suse 10.0 host with WinXP sp1 guest on Dell inspiron 8500 with 2.2GHz P4-M processor. When I do ifconfig in linux I get

    linux:~ # ifconfig
    eth0 Link encap:Ethernet HWaddr 00:0B:DB:96:4B:C3
    inet addr:192.168.0.2 Bcast:192.168.0.255 Mask:255.255.255.0

    When I do ipconfig /all in winxp I get NIC ID # 00-8B-E9-EF-D3-9D and an ip address of 192.168.0.5

    What is vnic0 in Linux?

    Where does it get its 10.37.129.2 which is not even a part of my network?

    Where does the vnic0 HWaddr 00:01:23:45:BE:EF come from? Is it just pulled out of thin air?

    Network card is BCM4401 (Broadcom) but Paralles says it is Realtek. Are these two really compatible?

    vnic0 is "sort of" just pulled out of the air. Parallels creates it, and that is what it uses to provide networking to your guest. The vnic is setup using realtek "psuedo" architecture and given an ip of 10.37.129.2.

    So WinXP actually goes from the 192.168.0.5 to the 10.37.129.2, then from 10.37.129.2 to 192.168.0.2 to the gateway at 192.168.0.1 to get to the internet? Is that right?

    I don't understand how the 10.37.129.2 is used on the 192.168.0.0 network.

    I believe that is the path for Windohs to get the net.

    As for the 10 to 192 thing, I don't know for sure, but I would say they do mapping within Parallels code.
