VirtualBox Error: “ahci-0-0″ (rc=VERR_DISK_FULL)”

I’ve installed Windows 7 on VirtualBox (Ubuntu host) and when I start the machine I get this error:

Disk full

The error message is this:

An error has occurred during virtual machine execution! The error details are shown below. You may try to correct the error and resume the virtual machine execution.

The I/O cache encountered an error while updating data in medium "ahci-0-0" (rc=VERR_DISK_FULL). Make sure there is enough free space on the disk and that the disk is working properly. Operation can be resumed afterwards.

Severity:   Non-Fatal Error

I thought it was the VirtualBox’s vdi hard disk drive that was full, but it was much easier. Just a “df -h” and I realized that my host disk was full!

    i am so stupid, i ran into the same problem and searched for it because i thought the vm was talking about the vm and not about my host.

    You’re welcome, Johann. At least I’m not the only one this happens ;-D

    Thanks! I had the same issue and was confused because my guest’s vdi had plenty of space. Stinking SSD’s and their small size!
