QEMU uses compat=1.1 (aka qcow2-v3) by default since version 1.7 and has support for it since version 1.1. Signed-off-by: Simon Deziel <simon.deziel@canonical.com>

Using this image format might not matter much because the qcow2 content gets copied to raw format anyway but it might be better to not rely on something legacy anyway. |

Do we know why it was added in first place, as it seems someone would have had to decide to use that option? |

Looks like it's been like that since distrobuilder grew support for VM images. Maybe @monstermunchkin would know more? |

QEMU uses compat=1.1 (aka qcow2-v3) by default since version 1.7 and has support for it since version 1.1.
Apparently, recent RHEL QEMU warn when using compat=0.10 images (https://bugzilla.redhat.com/show_bug.cgi?id=1951814)
