Key notes

The error occurred during initialization of VM is a classic Java issue when you are trying to run the VM. The error message can appear on any system you try to launch a virtual machine, including Windows, Mac, or Linux.

This issue occurs because the JVM allocates a big chunk of initial heap memory from the system that Windows or other OSes can’t provide. So, even if you have 8GB of RAM, if it’s already in use and the heap size is too big, you will see the error during the initialization of the VM.

Restart your PC and try to run Java before the other programs initialize, and make sure you’re running a 64-bit JVM. The 32-bit version can’t use more than 1.5 GB of RAM.

How do I fix error occurred during initialization of VM?

How do I fix error occurred during initialization of VM?

1. Change the Java heap size using Command Prompt

This command will set the Java Xms initial heap memory to a lower value, and now you can initialize VM without any issues.

From our tests in the WR labs, this solution worked in all situations to fix the VM initialization error. However, you can also apply the solutions below for the same effect.

2. Change the variables in the batch file

If you go too high with the virtual memory values, Java will display aCould not reserve enough space for object heaperror.

This simple solution will work on theCould not reserve enough space for 2097152kb object heaperror. But for this one, you should check if you’re using a 32-bit JVM. As we’ve mentioned above, the 32-bit version will not handle the 2 GB memory it’s trying to allocate.

3. Run a Bash command

If you still get the error occurred during initialization of VM, try closing some apps that are running in the background and try again. There is also the possibility that the physical memory is too low to run the VM.

Here are some of the error instances found by our Windows Report software experts:

Another server problem you might encounter is theIo.Netty.Channel.Abstractchannel on Minecraftbut this guide will help you.

To sum up our guide, the error occurred during initialization of VM is actually a problem with Java allocating too much initial heap memory, and from the WR lab tests, setting the values lower will fix the problem quickly.

You can do that by running a Command Prompt command, by editing the batch file, or by running a Bash command.
