Anyone tried a Radeon VII?

 

Yes, works. I have Asrock TRX40 Creator and Radeon VII. Need to work around the GPU reset bug though. (If you stop the VM and start again the Radeon VII will not initialise, need to reboot the host)

I found a working trick with a start hookscript: (this will briefly stand-by the host before starting the VM and it works to reset the GPU) 

root@ryzen:/var/lib/vz/snippets# more reset-gpu.pl
#!/usr/bin/perl

# Hook script for PVE guests to reset AMD GPU before VM start
# qm set 100 -hookscript local:snippets/reset-gpu.pl

use strict;
use warnings;

print “HOOK: ” . join(‘ ‘, @ARGV). “\n”;

# First argument is the vmid

my $vmid = shift;

# Second argument is the phase

my $phase = shift;

if ($phase eq ‘pre-start’) {

print “HOOK: $vmid is stopped.\n”;
system(“rtcwake -m mem -s 3”);

} else {
print “HOOK: got unknown phase ‘$phase’\n”;
}

exit(0);

Yesss, after three days messing around with passing on my RX580 to VM I tried the Radeon VII and now I can pass GPU to Catalina. 😎

I do still get a "vfio: Unable to power on device, stuck in D3" after stop-start VM but after a clean boot of Proxmox everything is fine. (The RX580 gave this error all the time)

Really interesting to hear about your kernel patches testing 😉

Got it setup so far with Catalina 10.15.4, changed to OpenCore 0.5.7 to get rid of graphics tearing issue. I can't seem to get GPU pass through working though. I do see it coming up in System Report but if I set Display to None in VM, I don't get any video out on my monitor. Just turns dark.

Ok, I'm new on this site. I have the Phanteks Enthoo Evolve X RGB case, looks awesome. Was hoping on a bare metal OSX solution but decided to jump in and run it on Proxmox. I consider to use the Radeon VII for my OSX and use the RX580 for a windows VM. Running OSX and Windows in parallel with dedicated graphics.

Anyway looking forward to get it running! 😁

Added my rig! Just put everything together, if all works it will replace my MacPro 5.1

I have a hard time downloading the VM assistant, is there something I need to do?

Wow, mind blown! So glad I found this. I took the plunge with a ASRock TRX40 Creator and 3970x so can't wait to get Proxmox installed. Great write up!

THanks. 😁
