I am posting this here because I don’t know where to start to track down the issue.
I have allot of VM’s and i get this error pretty consistantly.
I am not sure what logs or info to post here.
Let me know what a good place to start might be and we can go from there.
Where do you get this message from?
cave:
I do not use VirtualBox, so I cannot delve in any deeper.
While I am running the Virtual Machine . It happened when the OS I was running was doing an update. If I can find the complete message I will post it here. It disappeared off the screen and it crashed the Virtual Machine so I had to start it up again.
so it appears to be the second of the above mentioned possibilities …
… message came from inside some OS running inside VB
What OS that might have been is unknown as of now - but may be important information 
Sorry for the vague responses but I have several OS’s and it doesn’t matter which one I am in.
It might be a Virtual Box setting for Memory or CPU . I don’t know . That is why I am looking for some guidance. I reran the crashed Virtual Machine and it worked without crashing this time.
But I know it will happen again. Is there a Virtualbox log I can post. I don’t know where it puts it.
Thanks
Edit 1:
I’m thinking it might be an issue with how much memory my Host is using and the Virtual machine needs. Is there some commands I can use to check the memory?
so: this (my assumption) is not true:
The message came not from an OS running inside VirtualBox - but from VirtualBox itself.
That is where I am out - as I do not use VirtualBox
and thus could even not try to verify …
I think the host’s swap will be used when needed by the VirtualBox process - but I don’t truly now.
How to check or alter the amount of memory assigned to the VM in the case of VirtualBox:
I don’t know. (I don’t use it)
perhaps simply give it more … if you can
See my edit to my post.
Yes I that seems to be it.
It might be that the total amount of RAM specified for the VMs is large compared to the available RAM. Posting some system info (for instance, the results of inxi -zv8) would help, and also a list of the RAM allocated to each VM.
You can use (for instance) top to see how much memory is being used, and whether or not swap is being used (or even available).
like @Phemisters said:
you can only assign a portion of the RAM you actually, physically, have.
The OS this occured with is still shrouded in mystery.
First the OS I am testing with in the VM is Debian Testing.
Here is some more info:

Since you are running VMs I would certainly consider adding some swap: Swap - Manjaro
I don’t think you’ve said how much RAM the VMs are allocated in VirtualBox, but you certainly don’t have much room left in RAM if the VMs request more:
MiB Mem : 15618.6 total, 2991.5 free, 10855.4 used, 4394.7 buff/cache
MiB Swap: 0.0 total, 0.0 free, 0.0 used. 4763.2 avail Mem
When RAM is all allocated, I can imagine VirtualBox will allow a VM to fail or at least abort processing in the VM with out-of-memory errors.
You should always ensure your host has sufficient swap. How much depends on the load you put on the host, meaning the number of concurrently running guests.
I am always tinkering with the memory for each of the VM’s. Right now the Debian Testing is set at about 7GB. I could probably lower that
I have a 16GB swap file on the system. Not sure why it doesn’t show up.
Maybe not in my fstab. I will check that out.
… because the inxi output is from your host?
Your host doesn’t have any swap.
Debian runs just fine with just 2 GB of RAM
Changed the Debian to 2048MB on the memory setting. I will see how that performs.
Here is my lsblk -f:

Is the 24f2c822-affd-40ce-a183-d76c98c31df5 what I put in the fstab file for swap UUID?
Yes, I think you’d want something like this in the fstab:
UUID=24f2c822-affd-40ce-a183-d76c98c31df5 none swap defaults 0 0
I now have this as swap:
Swap:
Kernel: swappiness: 10 (default 60) cache-pressure: 100 (default) zswap: yes
compressor: zstd max-pool: 20%
ID-1: swap-1 type: partition size: 16 GiB used: 0 KiB (0.0%) priority: -2
dev: /dev/nvme0n1p13 maj-min: 259:13 label: N/A
uuid: 24f2c822-affd-40ce-a183-d76c98c31df5
I will monitor situation now that I have made these changes and see how it goes.
I don’t want to mark this solved just yet.
Edit 1:
I have run several OS’s and none have crashed yet. Maybe these settings are working.
I think with the lowering of the Machine memory down to 2048 and the addition of the Swap it has solved I think the original issue.
Now about the Swap file. Shouldn’t it clear itself out after not being used anymore?
After going in and out of VM’s it just seems to keep growing.
