The csi-hostpath-driver and volumesnapshots addons start much slower with minikube 1.33. Replacing them with rook ceph rbd storage, the kubevirt environments start up to 1.93 times faster. Start times before and after this change: | env | local before | local after | lab before | lab after | |--------------|--------------|-------------|------------|-----------| | rdr-kubevirt | 600 | 475 | 920 | 603 | | kubevirt | 270 | 230 | 603 | 312 | Signed-off-by: Nir Soffer <nsoffer@redhat.com>
It is easier to debug issues with a minimal environment. With
rook-cephfs and the required volumesnapshots minikube addon, the rook
environment is less minimal, but it is still quicker to start compared
with the full regional-dr environment.

We added csi-hostpath-driver as a quick temporary solution until we have
cephfs storage. Now that we have it, we can replace it and enjoy reduced
start time, in particular with minikube 1.33.
To replace csi-hostpath-driver, we have to add cephfs to the volsync
development environment. This is slower locally, but faster in the e2e
lab. For regional-dr, this is always faster, up to 1.82 time faster in
the e2e lab.
The main difference is cluster start time - minikube addons are loaded
before minikube start returns.
