You are probably using the vmxnet3 for the Ethernet bridge, don't use that. Use e1000-82545em instead, make the change in your xml. vmxnet3 makes the upload real slow for whatever reason.
It only shows how much of the disk has been allocated not filled but if you want trim to work on the disk add discard line on your vdisk so trim can be ran on it.
<driver name='qemu' type='raw' cache='writeback' discard='unmap'/>
Try this for your host passthrough
<qemu:arg value='host,vendor=GenuineIntel,+hypervisor,+invtsc,kvm=on,+fma,+avx,+avx2,+aes,+ssse3,+sse4_2,+popcnt,+sse4a,+bmi1,+bmi2'/>
Yea i think that your issue. I will building a real ryzen hackintosh in the next week with a 3600 for a friend and looking at your config.plist i see why it was so different from ours. What GPU are you using?
I have a 2700x and i don't use the amd patches at all. I just let the VM think its using Ivy Bridge. As far as your config.plist slim it down. You have a bunch drivers and kext you do not need. Take a look at @Leoyzen Git for a guide for how your EFI and config.plist should look. Read the opencore vanilla guide here it gives a lot of good info.
Anyone took a look at this kext?

Plist inside is a lot like the AGPMInjector kext we have been using here?
Try running the ram at 3200 or below. I have a 2700x it seems like ram overclocks can make the system unstable. Remember anything over 2133 for ram is a overclock.
If its too big there are smaller rx 570s that can do the job as well.

I use this one with my Catalina VM.
@ghost82 I'm running opencore 0.5.7. I had the pointer in the corner as well then I added DefaultBackgroundColor in the NVRAM/ADD section. I must have skipped over this at some point. Already had the correct resources folders in my EFI. So it works well now just had to hit the enter button to get into Catalina. Big test for me will be how well it works during updates.
@ghost82 Does opencanopy not autoselect for you? For me it just sits on the Catalina volume but does not auto boot it up. I know it's early in it's development so maybe it's just how it works right now.
Think he means this...Its in the flash device settings. I can only use Legacy mode myself. When using UEFI boot i can not get any GPU passthrough working. I have a 2700x and a x370 board.
