Re: [Libguestfs] Virt-v2v performance benchmarking part 1 [long]

From the non-verbose output of virt-v2v we can derive 3 times of interest for benchmarking performance: $ virt-v2v -i disk fedora-35.img -o null [ 1.1] Opening the source [ 7.3] Inspecting the source [ 12.4] Checking for sufficient free disk space in the guest [ 12.4] Converting Fedora Linux 35 (Thirty Five) to run on KVM [ 56.6] Mapping filesystem data to avoid copying unused and blank areas [ 59.8] Closing the overlay [ 60.3] Assigning disks to buses [ 60.3] Checking if the guest needs BIOS or UEFI to boot [ 61.3] Copying disk 1/1 █ 100% [****************************************] [ 62.4] Creating output metadata [ 62.4] Finishing off => Conversion time: 56.6 - 12.4 = 44.2
