barrier VS OSX-KVM

For software KVM you can use https://github.com/debauchee/barrier

I use it between a Windows PC & a Macbookpro (Linux version available but I don't have Linux)

libei looks useful. But IDK why libei is necessary to run Barrier with Wayland?

For client systems, couldn't there just be a virtual /dev/inputXYZ that Barrier forwards events through

And for host systems, it looks like xev only logs input events when the window is focused.

Is xeyes still broken on Wayland, and how to fix it so that it would work with Barrier?

With Barrier, when the mouse cursor reaches a screen boundary, the keyboard and mouse input are then passed to a different X session on another box until the cursor again crosses a screen boundary rule.

Barrier is a fork of Synergy's open core: https://github.com/debauchee/barrier

I have a similar gaming/WFH setup (2 monitors at 1440p 144hz) and I’ve been using Barrier instead of a physical kvm, and it works really well. Not sure if you’re open to a software kvm but if you are, I’m happy to answer any questions about it if you have any.

Have you tried Barrier? I casually used it to swap between my main rig and my MBP. Took a minute to get it setup but once I sorted it all out it worked pretty well. It has some settings and tweaks built in to address some of the layout issues you mentioned...

Barrier appears to handle PC switching only for the keyboard and mouse.

Sorry, probably not entirely on topic and can't answer anything reliable about the multimonitor stuff, but a tip regarding the 2 mice and 2 keyboards for the 2 different computers: use this: https://github.com/debauchee/barrier It's oss multi-os software that lets you use one mouse and keyboard (server) on several PCs (clients) easily over your LAN.

Barrier is a free and open source alternative.

Yes, I recently had to compile some stuff on Windows (I'm on an AMD Linux host) and VirtualBox just wouldn't start Microsoft's Windows dev VM (the one they provide for free for Virtualbox). I ended up learning how to use qemu and it works great...and as a bonus I was able to run a hackintosh (via https://github.com/kholia/OSX-KVM) and it works near flawlessly, which was something I was never able to accomplish with Virtualbox (granted I haven't tried in a few years).

I'm pretty happy with Qemu now, even if it's jsut a CLI interface. I was tempted to try the virt-* stuff, but honestly it seems like one more thing to learn so I'm going to hold off until I need something like copy/paste between VMs and can't figure it out in qemu direct.

Working on a patch to include it as a flake input instead of vendoring it in the repo, so this should no longer be true. I use the QCOW2s for OpenCore from osx-kvm that I have not figured out how to reproduce yet https://github.com/kholia/OSX-KVM/blob/master/OpenCore/OpenCore.qcow2

For almost a year, I have been coding a little project in Python intended to piggyback on the framework of kholia's OSX-KVM project, known as ultimate-macOS-KVM, or ULTMOS.

I just researched a bit, mac os x guest vm with pcie passthrough seems possible on linux.

VirGL is definitely an interesting project, but all one has to do to get GPU passthrough working (from a Linux QEMU host to any guest OS) is: 1.) research a cheap, secondary GPU that is natively supported by the guest OS, 2.) plug such a secondary GPU into a PCIe slot on the host and hook it up to the primary monitor with a secondary cable (D-Sub vs. DVI, etc.), 3.) setup Linux to ignore the secondary GPU at boot and configure a QEMU VM for the GPU passthrough. The whole process takes perhaps one or two hours and as works flawlessly, with no stability issues. (Switching across the two GPU cables can be accomplished in software by using Display Data Channel /DDC/ utilities and switching keyboard/mouse can be accomplished by using evdev /event device/ passthrough.)

I get "verification failed" error when using https://github.com/kholia/OSX-KVM

I also see there is KVM-OSX which looks to be actively maintained, but I haven't heard anything about it.

You can use qemu/libvirt/kvm on any Linux host to run macOS pretty easily these days[1]. I run Ventura on unraid with nvidea gpu passthrough and it’s been fairly painless.

You can also run macOS in docker, but it’s ultimately running through qemu/kvm as well[2]
