Virtualbox Error "VERR_NO_LOW_MEMORY"

[GiGaBiTe]

If you get this error come up when you try to launch a virtual machine in Virtualbox, I've found some information on the internet suggesting that it comes from one of two issues:

1) There isn't a large enough free block of system memory that is contiguous to allocate to the virtual machine trying to be run.
2) There isn't enough swap space to back system memory.

In either case, running this command should fix the problem:

Code: Select all

echo 3 > /proc/sys/vm/drop_caches
