It can bring a Core i7 to the ground.Figure 25.6 Double-click the VirtualBox.mpkg package to install. Ubuntu does bad things when this is enabled.

My cpu is Intel® Core™2 Duo CPU T5450 1.66GHz × 2. Opening Firefox will cause the system monitor to show cpu usage 100% in the guest, while the host shows that both cpus are evenly working around 60%. Idling with the system monitor open the (single) guest cpu never gets below 55% and could rise to 80 - 90% just by moving the mouse around. Is there anything I overlooked that could solve my problem?įeel free to ask for more info, and thank you for any help. I have 2 cpus and I can't give them both to the virtual machine. The host bios does not include a configuration option for machine virtualization. I am running a Toshiba m200 laptop with 4GB ram and shared video memory. I had a look around and I found contradicting opinions on VirtualBox versus VMware (free) so I thought to keep the former.īoth systems are updated, I installed the additions on the guest and I evenly split memory and video memory (64MB) between guest and host.

I run a guest ubuntu 12.04 on a host ubuntu 12.04, with VirtualBox, and the guest is much, much slower than the host ( ALT+TAB takes 4-5 secs).
