Dear forum
I'm totally new in this area and have therefore found and followed a tutorial on how to install ubuntu-desktop on a windows computer. I started installing Oracle VM Virtual Box and from there started installing Ubuntu 20.04.2.0 But when I start installing an error occurs and the virtual box tries to shut down the machine. I have attached the logs from VirtualBox. I do not know if have used too much memory on my computer 65% (6054 MB)? Please let me know if more information is needed.
Best regards a newbie

Reduce RAM to 3GB, unless you can put more RAM in the host PC.00:00:03.010685 Host RAM: 7907MB (7.7GB) total, 4677MB (4.5GB) available

Also, try only 2 processors in the VM instead of 4. More than necessary will slow down the VM, and modern OS's like two as a base.

Thx for helping out. You were spot on. I hope I have enough computer memory for metagenomic analysis.
Really appreciate it! thx again.

No idea what that is, but the name alone sounds memory-intensive.djs681 wrote:metagenomic analysis
Glad you're up and running!
One point of interest: How did the VM start running for a bit when there was insufficient RAM, you might ask. Virtualbox defaults to 'lazy' memory allocation, where it waits to take host RAM until the VM touches it. Linux OS's don't touch all RAM at startup, so they might run a while before hitting overprovisioned-RAM troubles. Windows OS's touch all RAM at boot, so these have troubles quicker.
There is a command to make Virtualbox stop being 'lazy' about RAM, but I don't remember what it is.
