The current version of VirtualBox (3.2.6) supports up to 16 GiB of RAM per VM.
FreeBSD community man, HubTou wrote a patch to up the limit to 48 GiB of RAM. http://forums.virtualbox.org/viewtopic.php?f=10&t=28215 I have tested it with 36 GiB of RAM on real hardware (RHEL5 Linux host). Host: Dual AMD Opteron Magny-cours (2x12) 24 core + 48 GB of RAM + VBox 3.2.6 OSE with HubTou patches. It was also tested on FreeBSD 8 host by HubTou. the following guest systems were able to boot and work: -RHEL-5.4/32-bit (PAE) -RHEL-5.4/64-bit -Windows Server 2003/x64 -Windows 7/x64 -FreeBSD 8.0/64-bit (tested by HubTou) On Linux guests I have also put a load - ramdisk (via tmpfs). Plus I have done the full "memtest86" test -- and it PASSED after 30 hours. After those tests I can recommend to evaluate the patch for inclusion into VBox 3.3.x line. Please evaluate the patch of 48 GiB RAM for guests. TODO: Test Guests: (for someone else) -Mac OS X Server -Solaris -Windows Server 32-bit PAE TODO: Test Hosts: (for someone else, unless you provide me with remote access into such a machine) -Windows -Mac -Solaris TODO: Write: (for someone else) -a similar patch for the Qt GUI. The patch is in the forum. http://forums.virtualbox.org/viewtopic.php?f=10&t=28215 Forum also includes the VBox Log and my test results. -- -Alexey Eromenko "Technologov" _______________________________________________ vbox-dev mailing list [email protected] http://vbox.innotek.de/mailman/listinfo/vbox-dev
