VirtualBox Out of Memory Error (VERR_NO_LOW_MEMORY) on CachyOS with 8 GB RAM Allocation

Greetings,

I’m encountering an issue with VirtualBox on my CachyOS system while trying to start a VM named “Dockers”. Despite allocating 8 GB of RAM to the VM—something my system should handle without problems—I get the following error:

Out of memory condition when allocating memory with low physical backing. (VERR_NO_LOW_MEMORY)
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ConsoleWrap
Interface: IConsole {6ac83d89-6ee7-4e33-8ae6-b257b2e81be8}

System Details:

  • Host OS: CachyOS
  • RAM: 32 GB (Available: ~25 GB as per free -h)
  • Swap: 32 GB (mostly unused)
  • Kernel: (can provide the exact version if needed)
  • VirtualBox version: Latest available in the CachyOS repositories.

What’s Strange:

This same setup was working perfectly last week. I haven’t made significant changes to the system, except for regular updates via paru .

Steps I’ve Tried:

  1. RAM Adjustment: Tested lower allocations (6 GB and 4 GB). The issue persists.
  2. System Update: Fully updated the system (paru -Syu).

Logs:

Request for Help:

  1. Has anyone else encountered this issue recently with VirtualBox on CachyOS?
  2. Could there be a compatibility problem with a recent kernel update or VirtualBox version?
  3. Are there additional steps I can try to resolve this issue?

Any guidance or insights would be greatly appreciated. Let me know if further details or logs are needed to investigate this problem.
