If I could make a suggestion for a change before GA: Could Parallels please disconnect and reconnect the virtual network cards after the MBP resumes from sleep? There is really no harm in this since the network was physically disconnected anyhow - but the benefit is that the guest OS will automatically do a release / renew on DHCP. I don't know how this works for everyone else, but right now I sleep my MBP as I move from location to location. Every time I resume, I have to go to each Parallels VM and disconnect / connect each NIC to get it to notice that I have changed networks. It works, it is just a bit of a pain. If this has been discussed before I apologize. There are so many posts on network stuff I couldn't find a similar post.
Sounds like a reasonable request, I don't think I've seen this before but certainly the networking topic has been discussed at length during the beta's. I'd like to see that this is implemented as an option so that it doesn't create a problem for others now that we are very close to GA.
