This error seems to be saying that you don't have enough free RAM to launch Java. Try closing unnecessary applications or increasing your page/swap space.
If your Virtual Machine freezes or becomes unresponsive you can restart the Virtual Machine by doing what?
Java virtual machine
Because it will work on all platforms because it's code is compiled through it's on Virtual Machine, the JVM (Java Virtual Machine).
Virtual Machine software does not lag if you allocate appropriate resources to it. If it is lagging, I suggest adding a processor core or increasing the RAM on your virtual machine.
Know the usage to understand if it is virtual machine or a physical machine.
How do you number of OS in virtual machine
You can't use all of your system memory to run a virtual machine because then there wouldn't be enough memory for the Operating System that's running the virtual machine to function. For instance, if you have 4 GB of system memory total, and your operating system needs at least a quarter of that (1 GB) to function, then your virtual machine maximum memory would be 3 GB.
Parallel Virtual Machine was created in 1989.
A 'virtual machine' is a software program which emulates another machine type. The virtual machine behaves exactly like the machine it emulates but uses the physical hardware of the machine it is running on. In other words, it translates calls intended for the virtual machine into calls that will execute upon the physical machine, effectively acting as an interpreter between the two machines.
Java virtual machine
Virtual machines are divided into two major classifications, based on their use and degree of correspondence to any real machine. They are either a system virtual machine or a process virtual machine.
This is because Java runs it's code through a Virtual Machine which compiles it and runs it. C will compile native on your machine and the code will be run directly, without the use of a virtual machine.
