I just noticed that Guest Additions were not installed. I went into Device Manager and all devices seem to be appropriately installed and accounted for (ie. The OS is on C: and the VM HDD are on D: (another drive entirely). I never really run more than one VM at a time.Įach HDD has at least 50GB of free space.


All hard drives are plugged in via SATA connectors on the motherboard (and are SATA based too). This is not a laptop, but my main desktop. Still lags, the mouse jumps around considerably when the VM does disk IO. I've turned off host IO cache, execution cap is at 100% with no bandwidth limit imposed. The VM in question had 2GB of RAM allocated to it along with one CPU. I think it might be a bus saturation issue? I have an Asus P5Q-E FWIW. IMO, it shouldn't matter as the mp3 require little disk access. VM Harddisk is on the same drive as the mp3 that is playing. CPU load is 25% approx on each processors.Īre there ways to limit the impacts of the VM on the host? I have a core2Quad with 8GB of RAM with slightly less than 50% available.

I'm currently performing Windows updates on the VM and it's interrupting the audio on the host (and the mouse is jumpy too). The VM is Windows 2003 on a Windows 7 host. I'm currently running a VM using Virtualbox.
