vbox file once VirtualBox UI is closed it is unchecked when opened again. I've just found that SSD setting is not stored in. When I added the line below manually I got finally what I needed (SSD+TRIM).Ĭode: Select all Expand view Collapse view Īnd another story is UI. Also nonrotational seems to be not set in machine config.

I tested offline with no VM started, this time both on Ubuntu 64bit host and Windows 7 64bit host - same results. TRIM appears finally in `hdparm` results but "-nonrotational on" is also needed otherwise.

Has somebody any clue how to get TRIM working on VDIs? mrp Posts: 4 Joined: 26. So if these are missing in guest then OS is not sending TRIM commands to VDI disk when files are deleted.

I run hdparm -I /dev/sda on guest and these entries are missing:Ībove lines are available on real SSD disk. I did some investigation and it seems that VirtualBox's SSD driveĭoesn't advertise TRIM support. However VDI file grows by that 1GB after each cycle. `df` on guest shows same disk usage which is right. Kernel is 3.2 and necessary 'discard' options where enabled for ext4 partitionĪs test I create and delete multiple files, totaly about 1GB for one cycle. However I can't get it to work on Ubuntu 12.04 Server guest, Virtualbox 4.2_80737 on Ubuntu host, SATA AHCI controller Image blocks through TRIM for SATA and IDE and UNMAP for SCSI when using VDI images". According to VirtualBox 4.2 changelog a new feature was added: "Storage: implemented support for discarding unused
