I've got a rather "messy" but practical configuration question.

Dual-boot laptop Windows 7/ubuntu.

In the Windows 7 environment, I also run a small number of vm's with ubuntu virtual machines. when Windows 7 is running, I want to access the partition containing the "native" home directory simultaneously from any VM and the host.

I figure the best way to do this is to run a really tiny virtual machine that mounts the Linux partition and exports the file system via NFS. I can then mount up the exported filesystem on all the other machines (host and guests)

This is what I've figured out so far:

Every guest is given a NAT interface so it can access the Internet

there is an "internal" network so that all guests can speak to each other

all guests have a host only network (one per guest) so they can talk to the host and vice versa

each guest imports NFS from the NFS server over the internal network
host imports NFS over the host only network to the NFS server.

am I in the right place or have I missed the networking model entirely? I've tried to share the host only network between multiple guests and it rarely works well. Usually machines would appear or vanish at random times and it was not nice.

One other problem I have with virtual machine networking in general (all vendors fail as far as I can tell) is that I should be able tell the system what my guest name is during the DHCP process, just like real systems and the DNS server should let me resolve a name like imacoolvm.vbox to an IP address. In the meantime, I'll keep using IP addresses. And changing them every time an upgrade changes the IP address range used for a network.

I will deal with this Windows 7 issue later but one of the places whereI have run into problems is with Windows 7 and it's marvelous "I'm too smart for my pants" networking services. I'm having trouble turning off the firewall for just one interface etc.

thanks for making one of the better VM's. Usually (and I hope soon always) it makes my life better.
