I am running Ubuntu 8.04 LTS Desktop Edition 64bit edition and after I installed VMWare Workstation 6.04 Linux x64 edition I got the following error when trying to start my virtual machines sitting on a NTFS USB disk volume.

VMware Workstation unrecoverable error: (vcpu-0)
Failed to allocate page for guest RAM!

Please click OK and locate the vm file. Open the vmx file with nano or another text editor and add the setting below. Save the file and try to start the virtual machine again.

mainMem.useNamedFile = “FALSE”

This setting doesn’t use named-file – use for VMs on USB-disks or other slow disks
Windows: useNamedFile= “FALSE” causes memory to be backed by the host’s swap space.
Linux: useNamedFile= “FALSE” causes a hidden file to be created in a temporary directory, which is immediately deleted when you power off the VM
