Ticket #6149 (closed defect: duplicate)
unable to unmount host cd drive VERR_DEV_IO_ERROR ubuntu
|Reported by:||cornbread||Owned by:|
This is happening to all of my windows guests windows xp and windows 7 32 bit and 64 bit on ubuntu 64.
The only way I've found to unmount a disk after mounting is to shutdown the system and go into the settings and set the drive from host to none.
