I just installed 14.04 Desktop, using "automatic partition setting" by the installer, with the "encrypt entire hard disk" option. I installed the latest VMWare (version date Apr 17th). Now whenever I launch one of my old VMs (haven't tried making a new one yet), I get a warning dialog box with the following text:

"VMware Player recommends 512 MB of system swap space for the set of currently running virtual machines. 0 bytes of system swap space is available. For optimum performance increase the amount of system swap space, or configure all virtual machine memory to use reserved host RAM under Preferences."

...with an OK button underneath. I'm getting it a few seconds after I ask it to launch the VM, but I think it's before it starts booting (but not sure). This message didn't appear in 13.10 with the older VMware Player.

I'm worried I might be doing something seriously wrong. Is it telling me I don't have swap on my host machine? (If so, how can I check that? GParted only shows the top-level partitions, maybe my swap area is inside the encrypted partition.) Do I really need the swap on my host? (I have 8GB of RAM, and I'm running 2 VMs at a time, each with 1 GB of RAM). Should I turn this warning off? (there's a checkbox for that) Or is it telling me my VM doesn't have a swap area? Here's what I get when I type df -h in my VM:

Filesystem Size Used Avail Use% Mounted on /dev/sda1 19G 4.1G 14G 23% / none 497M 164K 497M 1% /dev none 501M 0 501M 0% /dev/shm none 501M 80K 501M 1% /var/run none 501M 0 501M 0% /var/lock none 501M 0 501M 0% /lib/init/rw

And here's what I get when I type it in my host machine:

Filesystem Size Used Avail Use% Mounted on /dev/mapper/ubuntu--vg-root 680G 78G 567G 13% / none 4.0K 0 4.0K 0% /sys/fs/cgroup udev 3.9G 8.0K 3.9G 1% /dev tmpfs 789M 1.2M 787M 1% /run none 5.0M 0 5.0M 0% /run/lock none 3.9G 276K 3.9G 1% /run/shm none 100M 84K 100M 1% /run/user /dev/sda2 237M 54M 171M 24% /boot /dev/sda1 511M 3.4M 508M 1% /boot/efi /home/karjala/.Private 680G 78G 567G 13% /home/karjala

  • My VM used a swap file instead of a swap partition. You can find the link to increasing it here. – technogeek1995 Aug 21 at 13:43

I didn't have a swap area in my host machine. So I created a swap file as described here and that solved my problem. I'm not getting the warning anymore.

  • Also my host machine (with 8GB of RAM) has no hick-ups anymore. It was bad before the swap file. – alexk Apr 21 '14 at 19:44

While the above solution looks adequate, I was confused with the fact that I had included a 10GB swap partition during installation of 14.04.3. After looking at /etc/fstab I noticed that the line for the swap partition had been commented out during or after installation.

This page (could not mount /dev/mapper/cryptswap1) suggests this is a bug related to encrypting the home directory. I reformatted the partition as swap with GParted (because it was not recognised as such by the system), and verified the UUID (which had changed) with the command:

sudo blkid

Then I edited the line in fstab to include UUID of the swap, and uncommented it. After restarting my machine the system in general, as well as VMWare Workstation 12 Player successfully recognised the swap partition.

The VM is now much faster. This could explain why things were running very slowly with an older version of the VMWare Player - perhaps the same version that didn't complain about absent swap space.
