Hello,
My phisical disk has 32 GB free space,, I had 4 virtual machine ( fisrt 4 GB mem, second 4 GB mem, third 12 GB mem and the last 12 GB). The time I´ve started my virtual machine the swap occupy my free space. After some minutes I recieved the messagem " no free space".
So, I´ve moved one of my virtual machine to other datastore. Now I ´ve started all virtual machine and I have 19 GB free space.
Thanks all help.
