Dynamic processor allocation to virtual machine

Post by yanix »

I have a Mac OS X server Intel Core 2 Duo as my host machine and Ubuntu Server as my guest. I am planning to run applications demanding more than one CPU in the virtual machine. I know CPU allocation can be configured from the VB GUI processor tab or using the VBoxManage command tool, however; I would like to know if there is a way for the host to DYNAMICALLY allocate processors depending on the needs of the guest and if that the case, how can it be monitored?.

Thanks. :shock:

What you're looking for is the CPU Hotplug feature. Please read the manual, chapter 9.5, on how to use that feature.
