Panduan
- Periksa base image
qemu-img info /data/vms/example.qcow2
Contoh
image: /data/vms/example.qcow2
file format: qcow2
virtual size: 50 GiB (53687091200 bytes)
disk size: 324 KiB
cluster_size: 65536
backing file: /data/isos/template-ubuntu20.img
backing file format: qcow2
Format specific information:
compat: 0.10
refcount bits: 16
- Periksa target image VM
# virsh domblklist <nama_vm/domain>
virsh domblklist example
Contoh
Target Source
---------------------------------------------
vda example.qcow2
hdd /data/vms/sd-runner-cloudinit.iso
- Pastikan VM dalam kondisi menyala dan mulai flatten image
# virsh blockpull <nama_vm/domain> vda --wait
virsh blockpull example vda --wait
