Thanks @ghost82! I really appreciate your detailed answer. 2nd option seems great, but also I might create another osx vm and use a virtual disk there and add an nvme as cache. Maybe the performance would not be as good as now but backup/restore would be really easy. Will test it.

Hi Guys, So during the weekend I finally setup my OSX ( Macinabox rulez! ) and Windows 10 VMs with GPU passthrough ( Sapphire RX 580 Nitro+ for OSX Big Sur and GTX 1070 for Windows. For Unraid I am using the Intel integrated graphics ). For the OSX VM I used an NVME drive directly through VFIO ( for performance reasons ) so there is no virtual disk. How can I regularly back it up? Whats the best practice so if something happens I can recover it easily? Or should I re-create the VM using a virtual disk and use an NVME for caching? ( Would it provide the same or really close performance? ) I have two 4 TB parity drives and one 1 TB SSD for data drive currently. But will most likely add to these. Thanks in advance! Best Wishes, Matt

Hi Guys, So I am a new Unraid user and successfully created a Big Sur VM with the help of Macinabox. It works with VNC, but when I try to set my gpu ( https://www.sapphiretech.com/en/consumer/nitro-rx-580-8g-g5-se ) and switch input source on my monitor then I get a black screen. I tried it with and without rom ( https://www.techpowerup.com/vgabios/197894/sapphire-rx580-8192-171107 ) but same error. I also selected the sound card inside it and edited my xml manually as suggested in Spaceinvader One - Advanced GPU passthrough techniques on Unraid video. So multifunction is turned on. Bus ans slot is the same, gpu is function 0 and sound card is function 1. UEFI boot is turned off in Unraid. OSX SMBIOS is set to iMac 19,2 but also tried with iMacPro 1,1. Same error in both cases. In the BIOS I set the Intel UHD 630 gpu to be the initial gpu. Any idea to make the gpu passthrough work? System info Model: Custom M/B: Gigabyte Technology Co., Ltd.
