What percentage of performance drops when installing the OS in VirtualBox?

Question

virtual box

There is an AMD FX-6100 3.30GHz machine; 8G RAM; The SSD on which Windows 8.1 is installed - everything works fine.
If you install a clean Ubuntu Server (without X) on this machine, with VirtualBox - in which to deploy Windows 8.1 as a guest, how much will the system performance drop?

Answer 1

why?) I understand that perversion is an amateur thing. but I do not understand the buzz from such a perversion

Answer 2

Enable hardware virtualization in BIOS and VirtualBox. Then, if there is no activity in the virtual machine, your performance will practically not drop. I myself almost constantly use virtualbox at work (i7-2600/8Gb/Fedora) when I'm too lazy to deploy to esx, and occasionally at home (A-10 5800/8Gb/Win7), and somehow I had to raise the virtual machine on Yoga 11s (Pentium 2129Y) on a business trip /4.0Gb/SSD/Fedora). I did not notice performance failures associated with the processor, even on a weak netbook processor, unless, of course, running zip in several threads in a virtual machine. But it is better to physically separate the disks of the Host machine and the virtual machine. For disks, the performance drop is noticeable during IO operations in a virtual machine.

On the main OS (Win8.1) it became necessary to raise two guest OS (win8.1 & Ubuntu), made by Hyper-V.
The other day I had the opportunity to play around with Virtualbox.
I think that there are 5 VMs on Virtualbox on Linux, where it’s better after 5 VMs on Hyper-V under Windows (maybe I’m wrong ...)
That's just how many resources Linux will eat up ?... Percent 3% or 30%? what is the approximate order?

Answer 4

If you install a clean Ubuntu Server (without X) on this machine, with VirtualBox - in which to deploy Windows 8.1 as a guest, how much will the system performance drop?

if you install a clean Ubuntu Server (without X), you will work with VirtualBox on the command line, that is, you will not see the GUI of the guest window,
and in order to log into the guest you need SSH or RDP
(are there RPD clients in the nature that do not require X - good question )
