Error while reading when converting qcow disk to raw

Mark_667 · 02-06-2012, 11:33 AM

I'm trying to convert a qcow2 file to raw so I can store it on a LVM. I'm using the following:

Code:

#qemu-img convert -f qcow2 ./vm-101-disk-1.qcow2 -O raw  /dev/vg0/VM101

But keep getting:

Code:

qemu-img: error while reading

I've found plenty of people with the same problem on Google but no solutions.

Don't tell it what the input is.

I don't think the ./ helps either. Do the conversion in the subfolder so that the file name would be only needed.

qemu-img convert -O qcow2 test.vmdk test.qcow2

get rid of the ./

Thanks, I successfully converted a qcow2 file using the changes jefro suggested, but for some reason I get the same error on another qcow2 file using the same format as for the successful conversion?

qemu-img is not able to find or read the file is what it is saying. Path maybe?
