Iscsi disk size for saving the guest state is insufficient!

[Anushree-Mathur]

Architecture : PPC64 OS : RHEL9 In the restore.py file when i am trying to save the guest image state after creating the iscsi disk it is failing with error message as no space left on device! By default the image size for iscsi is 1024M but the size of image at the time of saving is slightly larger than this.

(0310/1020) type_specific.io-github-autotest-libvirt.virsh.restore.expected_option.non_acl.iscsi_file.qemu_namespaces_mount: FAIL: error: Failed to save domain 'virt-tests-vm1' to /dev/sdb\nerror: operation failed: /usr/libexec/libvirt_iohelper: failure with /dev/sdb: Unable to write /dev/sdb: No space left on device\n

Can anyone tell me if this is architecture specific or generic?
