Re: [VBox-users] Doubt about amount of virtual machines are supported on Virtual Box !

Thanks Pablo for de answer !

But, take a look this:
Sizing Guidelines for Oracle VM VirtualBox Servers

We found that the 'VMs/core' unit, while being striking, is a fuzzy statement as the available CPUs today differ by at least a factor of 2 in performance and that even ignores older CPUs customers may want to reuse. Therefore we decided to also provide the 'SPEC CINT2006 Rate (peak) / VM' value. Statements made based on this unit are valid for a longer time as they abstract from a concrete CPU, while statements based on 'VMs/core' hold true for cores showing roughly the same performance only.

CINT values for a vast number of CPUs can be looked up from the database of the Standard Performance Evaluation Corporation (SPEC) at http://www.spec.org/cpu2006/results/rint2006.html or by running the provided test suite.

The numbers for this section have been updated based on a new test run. We were able to run 100 VMs on a X4170 with two E5520 CPUs having 4 cores each. The SPEC CINT2006 Rate (peak) for E5520 CPUs is ~200 which results in a cint / VM value of 2.

  • Number of cores = number of running desktops / 12.5 
    Example: A server roughly equivalent to a X4170 with two E5520 CPUs can support up to 2 * 4 * 12.5 = 100 running desktops

I dont understand as they got this result...   12.5


Cheers,

Wagner Alonso.

Hello,

I would like know, If there is a limit number of virtual machines on
Virtual Box?

I didn't find on documentation !
    
Hi Wagner,

I believe the constraint is solely on the Host O/S' resources.

Cheers,
