Rhai SALS with following features

CloudHypervisor start/stop/list/create/delete VM's on top of QCow2 with snapshots
QCow2 management snaphot/create/... build Ubuntu 24.04, Alpine then run in CHV

features

insert set of ssh keys and/or root/passwd combination and make sure root can login
rhai script interface, runs from runner
info which needs to be remembered remember in local herodb (metadata), need rhaj scripts to work with those
work with slices local computer partitioned in 1 GB slices (max of 16 per computer)
is only working on local basis, has no notion of anything out of the node
allow zinit/supervisor/ourdb to be started automatically with a secret

if time

firecracker VM's as faster backend for short living
test with mycelium & herorunner/supervisor on top of zeros (supervisor runs in zinit) so we can remote use it

ideas to explore

image has zinit inside
snapshot qcow2A -> gives new qcow2B with certain max size
mount qcow2B on path lets say /mnt/B
in /mnt/B copy the files you want e.g. herodb, supervisor, zinit
put the zinit config

params

slice nr's
zinit config
which cmd's to copy into the vm (its a pre understood list)
