Depends on lima-vm/go-qcow2reader#61 How to setup ASIF as diffdisk: 1. Create an instance for test, then stop it. ```console $ limactl start template:ubuntu --name=asif-test --tty=false --log-level=fatal; limactl stop asif-test --log-level=fatal ``` 2. Convert `diffdisk` with ASIF image. (original will be renamed to `diffdisk.raw`) ```console $ hack/convert-diffdisk-to-asif.sh asif-test + instance=asif-test ++ limactl list asif-test --format '{{.Dir}}' + instance_dir=/Users/norio/.lima/asif-test ++ head -c 4 /Users/norio/.lima/asif-test/diffdisk + head4bytes= + case "${head4bytes}" in ++ limactl list asif-test --format '{{.Status}}' + instance_state=Stopped + [[ Stopped == \S\t\o\p\p\e\d ]] + diskutil image create blank --fs none --format ASIF --size 100GiB /Users/norio/.lima/asif-test/diffdisk.asif /Users/norio/.lima/asif-test/diffdisk.asif created ++ diskutil image attach -n /Users/norio/.lima/asif-test/diffdisk.asif + attached_device=/dev/disk5 + dd if=/Users/norio/.lima/asif-test/diffdisk of=/dev/disk5 status=progress conv=sparse 107152496640 bytes (107 GB, 100 GiB) transferred 115.003s, 932 MB/s 209715200+0 records in 209715200+0 records out 107374182400 bytes transferred in 115.228413 secs (931837727 bytes/sec) + hdiutil detach /dev/disk5 "disk5" ejected. + mv /Users/norio/.lima/asif-test/diffdisk /Users/norio/.lima/asif-test/diffdisk.raw + mv /Users/norio/.lima/asif-test/diffdisk.asif /Users/norio/.lima/asif-test/diffdisk + echo 'Converted diffdisk to ASIF format successfully' Converted diffdisk to ASIF format successfully ``` 3.
