[Libguestfs] [PATCH v2 0/3] rhv-upload: Support import to qcow2 disk
Add support for qcow2 disk format, enabled by imageio NBD backend in RHV 4.3.
To use this feature manually, you can run virt-v2v with "-of qcow2".
Here is example run:
Source disk:
$ qemu-img info /var/tmp/fedora-30.img
image: /var/tmp/fedora-30.img
file format: raw
virtual size: 6 GiB (6442450944 bytes)
disk size: 1.15 GiB
virt-v2v:
$ ./run virt-v2v \
-v \
-i disk /var/tmp/fedora-30.img \
-o rhv-upload \
-oc https://engine/ovirt-engine/api \
-op /var/tmp/engine-password \
-on v2v \
-os nfs1-export2 \
-of qcow2 \
-oa sparse \
-oo rhv-cafile=/etc/pki/vdsm/certs/cacert.pem \
-oo rhv-cluster=fc30 \
-oo rhv-direct=true
