I have regular problems with connectivity but ONLY when Parallels is running with a Windows 8 VM. The problems occur on the host (MAC), NOT in the VM. What happens is that the DNS resolution takes ages (well, 4-5 seconds); the transfer speeds are still the same, but going on a website is very slow before the page starts loading. If I shut down parallels, it stops happening. If I restart parallels, it comes again. If I disable networking on the VM, it works properly. I tried shared and bridged, it is the same result. I tried to set the VM to use different DNS servers (my provider's, Google's, OpenDNS') and the result is the same. If I put the VM to sleep, it works properly. It happens while there is no networking use on the VM. What should I look into? it's VERY frustrating!
