Troubleshooting slow network (Win7-64 guest, Mac OS X host)
Posted: 25. May 2010, 23:24
I've got a Win7 64-bit guest running on a Mac OS X host (Snow Leopard 10.6.3, VirtualBox 3.1.8 with guest additions installed). I use it primarily to host MS SQL Server to support local Web application development on my Mac. For the most part, I just start it and never sign in. Occasionally, however, I will sign in and fire up IE8 to test something a Web app on the Mac OS host system or on an external server somewhere... but it has been a couple weeks since I last did so.
Somewhere in the past couple of weeks -- since I last used IE on the Win7 guest -- I've obviously acquired some network-related problems. Connectivity from my Mac OS-hosted application server to the Win7-hosted SQL Server seems fine. However, network access from IE on the Win7 guest to the Web server on on my Mac is horribly slow. I can sit watch the tail of the apache log, and after pointing IE at an HTML page, I'm seeing a request come from the guest for an image file or stylesheet file, etc., about every 30 seconds or so, causing the page to take forever to load. This is in contrast to a page request from the Mac host for the same page, which generates an almost instantaneous flurry for all of the needed files.
In addition, IE on the guest can no longer see anything outside of the host (e.g., cnn.com or google.com).
In that period, I have updated my install of VirtualBox from 3.1.6 (with guest additions) to 3.1.8.
I also have a couple of other VMs with Linux (Ubuntu 10.04, Linux Mint 9) installed on this same Mac OS host, and connectivity from those guests to the Web server on the host is quite fast (very comparable to a host-based browser), but I can't see the outside world from these guests when I am connected on the wired network at work (although they /can/ when I am connected via wireless at home). I'm not sure whether IE8 under the Win7 guest can see the outside from home via wireless connection; I will check this evening and follow up here.
How do I go about troubleshooting the network connectivity problems?
1. Horribly slow connectivity from Win7 guest to host
2. No connectivity from any guest to outside world when connected via wired connection
Any help would be greatly appreciated, to say the least.
