Tighter integration between Linux host + macOS guest?

[ylluminate]

Due to the joke that was WWDC and Apple's disdain for what propped them up (an original support and deep consideration for serious software developers and security experts), I think a lot of folks are finding our way back to Linux options. Sadly this is not an easy migration due to large investments in macOS software, etc.

To this end we need to figure out a tighter emulation / hypervisor option that will allow us to continue running macOS 10.14, 10.15 and x86 instruction capable versions for years to come with tighter integration.

I see your solution dedicates a GPU to a macOS vm guest (which GPU could be used to, for example, provide multi-monitor support) with the possibility of an additional single additional GPU dedicated to a Linux environment.

My hope and goal is to have an integrated / native-feeling integration between the host and guest(s).

A few points that I think would be critical and I'm curious if you might know of existing options or if we need to pursue development:

1. Are there existing options that would facilitate a very tight low-level pasteboard between the Linux host and macOS guest? 2. Are there any options that would allow "drag n' drop" and/or copy-paste of files between the host and VM?
2. Has anyone integrated the home on Linux with the macOS guest such that it is also home there without any significant problems with such integration? This seems doable with SAMBA (since NFS support has gone to the toilet in 10.15), but perhaps there are better options?
3. Do you have any ideas for other integrations that could make the experience more cohesive?

If these options don't yet exist, where would be a good place to go to collaborate with others who would want to implement these things and/or to donate to developers to refine this effort?
