Hello,
I will try to describe my problem as well as possible.
My mac (2015) is currently in Sierra 10.12.4 (But I have this problem since the first installation of VirtualBox, about 8 months ago.)
I use VirtualBox to virtualize my Windows / Linux.
I encounter a problem with certain programs such as Packet Tracer, when I run it on a Windows or Ubuntu machine, it takes 100% CPU on the client machine and raises the mac to about 100° / 6000rpm.
Already realised :
- I have disabled the Windows Update service that are also causing problems with cpu on my windows virtualised machines.
- Thinking of a memory leak or a bad installation of Windows, I decided to reinstall a Windows 7 / 10 / Linux from an official ISO. Same problem
- Tested version 6.3, 7.0 of packet tracer on Windows 7 / 10 and Ubuntu distrib.
- Fixed the resources allocated to the virtual machine related to the processor at 60%.
Remark :
For example witch packet tracer :
- I observed that when I run Packet Tracer the processor does not go above 5% in use.
Same when I add switches, machines.
- The processor rises to 100% only when I connect two routers together with a serial cable. The problem appears to only occur on packet tracer used on a virtual machine.
My mac does not heat abnormally when I don't use VirtualBox.
I try with the same configuration (Same OS, VirtualBox version) on another mac form 2013 and the problem seem to not appear.
Attach you can find an example of my issue with packet tracer.
Thank you in advance for your helpI am working on a mac with El Captain. Running a vagrant environment inside of of VB. Whenever I stand up my vagrant environment including VirtualBox, VBoxHeadless uses 100% of my CPU. My laptop fan runs constantly. When I halt my vagrant everything goes back to normal. I've tried changing some setting in my VirtualBox. under system for Processor I changed my Execution Cap down to 40%. Also under Acceleration I unchecked Enable Nested Paging (I read that helped with some else). Neither option has helped so far. I am not sure what other information may help with the trouble shooting. Please let me know.
Thanks in advance,
Chris
For Mac OS X hosts, Oracle VirtualBox ships in a disk image ( dmg ) file. Perform the following steps: Double-click on that file to have its contents mounted. How to Install Mac OS X Snow Leopard in Oracle VM VirtualBox or VMware® Workstation 9 For VirtualBox users Just Fallow my Steps. However installing MAC OS X on non- Apple hardware is a bit tiresome and complicated. This is an easy guidebook, Install OS X El Capitan VirtualBox is basically a program, over which you can install and eventually run OS X with Intel-based and AMD processor. You would be happy to know that, this.
