Disk image from base image

qemu-img create -f qcow2 -b ../images/centos-native/x86_64/CentOS-Stream-GenericCloud-9-20220330.1.x86_64.qcow2 -F qcow2 .vmm/disks/fs.qcow2 40G

-b is relative to the created image

Networking

I think vde should be easy enough to implement for vm to vm communication.

user networking can be used for host and internet access. It also has options for host_fwd and smb

user networking has smb support. It uses samba.

There is also virtio-fs, which uses a daemon on the host and some special devices. It has been tested on a Linux host, but not on other platforms.

drives(or disks) could be moved to the root. They aren't really properties of the vm, but are attached to a vm.

maybe a gui option? maybe more machine options? Maybe a provider option?

cloud init's meta-data and user-data can just be a dict under the disk spec. The yaml file can be created ad hoc and be written to an ISO file.
