Ticket #6056 (closed defect: invalid)
Hanging when 3 VMs are running on Windows 7 x64 host
|Reported by:||ibobak||Owned by:|
I have 3 virtual machines:
- Windows 2003 Enterprise x64
- Windows 2003 Enterprise x86
- FreeBSD x86
All of them were originally created by VirtualBox (they are not imported from VHD or something like this).
The host is Windows 7 x64 - this is HP Pavilion dv7 (Processor Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz, 4 GB of memory, 2x250 GB hard drives)
As soon as I run all 3 virtual machine all together - my host machine becomes not responsive: the keyboard and mouse do not react on pressing/movement, processor goes up (I hear how the fans are working hard), and it hangs for an hour until I simply press power off.
If I run only 2 of them (any 2 of them) - everything is fine.
I feel that virtual box simply cannot run more than 2 guests simultaneously. I had such situations previously with other 3 machines - as soon as I've launched the 3rd one - everything hanged.
Can anyone suggest me, what should I do (maybe to unplug some option in the settings?) in order to force all 3 VMs working?
When I had VMWare Workstation, I could run even 4 guests on this PC - everything was fine and there were no such problems.
Thanks in advance. Ihor.
Note: the amount of memory which they consume in total is 3GB, while I have 4GB in my system. So everything is fine with that.
