This tutorial for installing macOS Sierra has been adapted for Proxmox 5 from Kholia’s GitHub project for installing into vanilla KVM. There is more documentation there which will help out with enabling extra features and diagnosing problems!
I’ll assume you already have Proxmox 5.1 installed. You also need a real Mac available in order to download High Sierra from the App Store and build the installation ISO. Your Proxmox host computer must have an Intel CPU at least as new as Penryn (I believe you would need a a custom Mac kernel in order to use an AMD CPU).

When emulating macOS on Proxmox, it seems that we are forced to set the guest’s CPU type to “Penryn”. This is a very old architecture, and is missing some features that could unlock higher CPU performance. In particular, I wanted to use AVX (for accelerated stream processing) and AES-NI (for encryption), but macOS panics on boot if I set the CPU to Sandy Bridge, which would match my CPU which includes those features.
Luckily, kholia over at the OSX-KVM project has discovered that we can keep using Penryn, but enable the passthrough of individual advanced CPU features and have Sierra use them, even though Penryn never supported these features.
