Memory Percentage Checks not well suited to larger RAM amounts => Fixed in SVN

[Dave Bialac]

When creating a virtual host on a system with a substantial memory pool, it does not make sense to use percentages to determine if a virtual machine is occupying too much memory. For example, my system have 3.25GB of ram. Due to political issues, I can not run the OS of my choice, but I can virtualize it. In vmware, I'm given the option of using up to 2892MB of memory for the VM, and both the Host (Windows XP) and the Child run well. Virtual box arbitrarily and needlessly limits me to around 1.6MB. If I expand beyond that, I get an error message saying that the memory cannot be allocated -- something that is obviously false because VMWare can do it.

That's a bug in the create new VM wizard. The settings dialog allows you to choose up to 75% of your host's ram. We will not change the 75% rule as people too often assign too much memory to their VMs.

VBoxManage has no such restrictions.

The RAM limit for new VMs was increased to 75 percent (as intenteded). People willing to assign more memory can do this using VBoxManage.
