Description
We can create a raw disk via: VBoxManage internalcommands createrawvmdk -filename rawtest.vmdk -rawdisk /path/to/rawdisk.img
Since VirtualBox 4.2 it appears that the AHCI virtual controller supports the ATA TRIM command. However, only the VDI image file backend actually implements it.
My request is for the RAW disk image backend, when receiving a TRIM command from the guest, then hole-punching the RAW disk image file. This will save disk space of the host system.
