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


Error ID:
BLKCACHE_IOERR
Severity:
Non-Fatal Error

Virtualbox thinks the host disk partition that the VM's disk file is on is full.
