Thanks Kashyap for replying. QEMU has permissions to the directory which is having images. I will look into the AppArmor issue and find out more about this. Also as per suggestion from the link i have uncommented the user and group from the qemu.conf file - https://github.com/jedi4ever/veewee/issues/996
By checking more on the AppArmor and sVirt issue , i have modified the qemu.conf for security_driver="none". The result for this is no permission error but another error which can be related to QEMU 2.3.0 virsh # blockcommit vm-01 vda --verbose --pivot --active Block Commit: [100 %]error: failed to pivot job for disk vda error: internal error: unable to execute QEMU command 'block-job-complete': The active block job for device 'drive-virtio-disk0' cannot be completed Searched more for this type of error and found - https://bugs.launchpad.net/qemu/+bug/1455475 Looks like bug in QEMU 2.3.0 . Checking now with QEMU 2.1 for the same. Let me know if anything to more look for.
