Not having much luck with Parallels support, so trying here. When my Macbook Air (2012) wakes up from sleep, my Ubuntu Linux 12.04 Server VM (No GUI) will lose its network connectivity, forcing me to restart it. As you can see in the following ifconfig -a extracts, the VM seems to lose its IP. Renewing the address does not help. I am still able to access the VM through the console, but not through SSH. I installed parallelsTools although I'm not sure it is required for the Server version of Ubuntu. One thing to note is that if I force my MBA to sleep and waeke it up, the VM seems fine. It really only manifests itself when leaving it overnight, making me think it might have something to do with Powernap or something like that. Has anybody noticed this problem?
