Take the 2-minute tour ×  I have a quick question. I have a
64bit Ubuntu 10.04 server with 24GB of RAM and is used as a
VMWare Workstation 7.1 host. I would like to use an in-memory
drive for the VM Memory location, which I setup as the
following:  tmpfs /mnt/vmware tmpfs defaults,size=100% 0 0  That
all works. Next I want to allocate 16GB of RAM to the VM, I know
its a lot but we do a lot of processing that needs a lot of RAM.
After the VM is started and I run df -h, I get the following for
that drive:  Filesystem             Size  Used  Avail Use%
Mounted On tmpfs                  24G   11G   14G  44%
/mnt/vmware  Why is it that the Available (14GB) size does not
equal the Size (24GB) of the drive? And why wouldn't the whole
16GB get allocated to the memory space, which is what i set in
the vmware guest .vmx file? Is there a limit to the space that
can be allocated to a tmpfs file system?  Thanks for your time.
