Since i virtualized a bunch of my PC’s, i’m having some trouble lately with my Windows 2008 Server running Hyper-V RC1. I get BSOD’s way to much, somewhere around 1 every 2 days. I was lucky that i witnessed the BSOD on 2 occasions and i could see vmswitch.sys being mentioned on the screen as the possible culprit. This lead me to the following Microsoft TechNet Forum post.
Well, that can’t be a coincidence that this thread mentions the same NIC as i have on my Gigabyte EP35-DS4 motherboard. It seems to be a problem in the driver for this NIC (an on-board Realtek RTL8168/8111 Family PCI-E Gigabit Ethernet NIC). So probably updating the driver should help, although i don’t know yet how to handle this if the driver is not digitally signed..we’ll see. The replacement RAM was already purchased, cause the problems started around the same time that i added an additional 4GB so i blamed that at first… well, nevermind, a bit of spare RAM is always handy 🙂
