Build 1940 became a nightmare for my host only networking setup, because for some reason en2 appears again as an active interface. I found out that the infamous 192.168.2.x address my guest only adapter was getting in DHCP is given by MacOSX when I turn on sharing, and NOT by Parallels!. Now that build 1940 "fixed" the parallels DHCP on my machine, nothing worked. I found out that if you turn internet sharing ON, and have parallels in host only networking, quitting the prl_dhcp process (parallels dhcp server) makes the virtual machine grab 192.168.2.x from OSX directly. This is exactly the behaviour I had in previous builds (and what works for me!) Parallels: Maybe a "Disable DHCP server" would make this easier. I think a lot of confusion on host only/internet sharing has to do with who handles DHCP. My 2¢
