[KVM] Specify the source disk format if necessary, when converting a disk (using 'qemu-img convert') to another disk format (while creating a volume/template/snapshot).

ISSUE TYPE

• Improvement Request

COMPONENT NAME

Volume, Template, Snapshot

CLOUDSTACK VERSION

main

CONFIGURATION

CloudStack + KVM

OS / ENVIRONMENT

SUMMARY

Currently, the 'qemu-img convert' auto detects the source disk format while converting to another disk format when creating a volume/template/snapshot. Sometimes, when auto detect the source disk format is not possible, or source disk format is explicitly passed, it is required to specify the source disk format in 'qemu-img convert' cmd for the conversion.

STEPS TO REPRODUCE

EXPECTED RESULTS

Enable 'qemu-img convert' to take the source disk format if necessary.

ACTUAL RESULTS

Unable to specify the source disk format to 'qemu-img convert' while converting to another disk format (when creating a volume/template/snapshot.)
