Description
Test setup is the following:
- Host machine: Linux, 16GB RAM, 16GB swap.
- Guest 1: Linux, 5GB RAM, 2GB swap, 4.5GB ramdisk
- Guest 2: Linux, 5GB RAM, 2GB swap, 4.5GB ramdisk
- Guest 3: Linux, 5GB RAM, 2GB swap, 4.5GB ramdisk
- Guest 4: Linux, 5GB RAM, 2GB swap, 4.5GB ramdisk
Steps to reproduce:
- Start all 4 VMs.
- Start growing ramdisk.
When host free RAM is close to zero - VirtualBox will abort one of the VMs. Swap usage on host is still very low.
Please add the option to allow VM to swap, so all of those 4 VMs will be able to work together, even if slower (swap based on SSD disk makes it not so bad).
