Why starting a KVM Virtual Machine fails with "error: unable to open disk path /dev/sr0: No medium found."?
Issue
-
When starting a VM with "virsh start <vm name>" after installation of the guest finished from the cd/dvd and the cd/dvd was ejected from the drive, it fails with the below error message.
error: Failed to start <guest name> error: unable to open disk path /dev/sr0: No medium found.
-
If a cd/dvd is inserted to the driver, the vm will start fine without any problem.
Environment
- Red Hat Enterprise Linux 6
