block I/O error in device 'drive-ide0-0-0': Invalid argument (22)

Is /opt/cibai/database on a special filesystem or exotic storage setup?

Please check dmesg on the host for any kernel messages regarding I/O errors.

Please try reading the file on the host to check whether the I/O error is happening on the host and not related to KVM:

$ dd if=/opt/cibai/database of=/dev/null iflag=direct

Hi Stefan,

When I booted the VM, dmesg actually produced this message, I am not sure is it a warning or error.
