[Solved] unable to start the VM

[nsmuelle]

Hi everyone,
Today I installed ros and webots on my Ubuntu VM (hosted on windows 10) and then shut it down. I am now unable to start it again and I get the following error message : "a critical error occurred during the execution of the virtual machine and the VM has been stopped".
The message also says that I should attach the VBox logs and post a message on the website which I'm doing now.

Could someone please help to find out what is the error and how I could correct it ?

Best regards.

Looks like memory is heavily overcommitted:

00:00:02.324922 Host RAM: 16228MB (15.8GB) total, 5944MB (5.8GB) available
00:00:02.445478   RamSize <integer> = 0x00000002c3300000 (11 864 637 440, 11 315 MB, 11.0 GB)

Restart the host to free up memory, or reduce the guest memory slider.

Also try two cores in the guest. Your host has 4, so there's room.

Thank you very much ! I am now able to start it again

Thanks for reporting back. I'm going to lock the thread now because the title is way too generic for my taste. Traditionally these always encourage "me too" posts.
