if i start playing an MP3 in win7, host cpu usage runs up to 90. when win7 64bit rc is idling, VirtualBox shows a pretty nice steady 13 CPU usage on host. using sound with this driver kills virtualization performance on my 2.4ghz MBP.

This should enable point 3, but double check to be sure. My server doesn't have the resources to run virtualized, and quite a lot of the value I get from it is flexible storage management (software raid, lvm.).

Then I added the raw hard disk vmdk to the vm, restart. We have tested VirtualBox 7.95 against malware with several different programs. The vm has one sata controller with normal virtual disk on host filesystem containing fedora core 15 beta. Have to run virtualbox gui as administrator, or else it complains disk is not accessible on startup of gui manager, so clearly it's doing some kind of read check, and that's succeeding.Ĥ. Had to run virtualbox gui as administrator to be able to add this to a vm. removed drive letter) in computer/manage/storage management.ģ. Physical hard disk is 200GB on a USB to SATA bridge.
