go to the domain shares and then to macinabox catalina, delete this /mnt/user/domains/MacinaboxCatalina/macos_disk.img then replace this tag <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='writeback'/> <source file='/mnt/user/domains/MacinaboxCatalina/macos_disk.img'/> <target dev='hde' bus='sata'/> <address type='drive' controller='0' bus='0' target='0' unit='4'/> </disk> with something like this <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='writeback'/> <source dev='/dev/disk/by-id/ata-WDC_WDS480G2G0A-00JH30_193953801186'/> <target dev='hdc' bus='virtio'/> <boot order='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/> </disk>

post your full xml to see what is wrong and give you examples on how to do things

You must do all the changes via xml editor, post your xml

Id try to upgrade from clover to opencore first as clover often does not play well with added hardware, after that, try passing it throgh again.. Look for lyoncen opencore kvm in google

Pass it throgh just like any other pcie device.. Look for the iommu group and use a hostdev tag with it

Yes, I had failed too.. Just restored My backup.. Will wait

As soon as you passthrough an usb port you can use any usb compatible hardware wifi/bluetooth etc

I have updated the VM to the latest catalina and gonna make a backup of that and then gonna try to update to big sur I am using OC with all the kext updated to the latest and did the update with the VNC display as it needs to reboot several times and amd reset bug from my 5700XT wont allow a smooth process

has anyone tried the catalina update?

Mmm dont know if apple would bring support for those any time soon or ever?

I have just received My 2x retina 27 inch monitors from dell and I am breathless.. macos wont perform any good or look Better in any apple hardware in existance today Im running side by side macos on My 5700xt and windows 10 on My 3080 could not be happier

Heck I tould you to copy My xml.. Everything is on the same bus And slots only thing diferent is the function, thats because in reality the card is in just 1 slot with all the same resources, you can not split the card resources up or it will malfunction

Mm to get use to it? To see what is macos all about? Not everyone have ever owned an apple product, I am a macos power user as I am software developer, know and use macos the same as linux and windows but I My first "mac" was a NUC I turned into hackintosh.. Never bought and Never will buy a mac

Google opencore kvm, lyonzen github, download the efi folder, Mount your OS efi partition paste the efi folder there, download opencore configurator, Edit config.plist and change the smbios to get the 1.1 imac pro 2017 save and reboot still in vnc, if everything is good, you should see improved resolution, after that passthrough your card Dont forget to copy the xml OS tag from for exsmple your windows vm

Mm I havent ever managed to passthrough amd cards with clover, go for the opencore kvm amd try again In the other hands, besides you need to change the OS tag to work with your native ovmf files for opencore , I dont see anything wrong

You can Always backup your vm, upgrade and if it crashes, just restore your backup lol.. Even in baremetal is Better to wait for upgrade confirmation by experts. Anyways, you should start the process asap to get use to it and the possible issues you may find

Yes it is possible, just change the path to the vdisk for the path to your unasigned drive thats it.

Long story short, get RX 470/480/570/580 for OTB compatibility and decent performance from sierra upto latest or navi 10 from Catalina and up

which gpu are you passing through?

<hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x4a' slot='0x00' function='0x0'/> </source> <rom file='/mnt/user/isos/Sapphire.RX5700XT.8192.190722_2.rom'/> <address type='pci' domain='0x0000' bus='0x03' slot='0x00' function='0x0' multifunction='on'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x4a' slot='0x00' function='0x1'/> </source> <address type='pci' domain='0x0000' bus='0x03' slot='0x00' function='0x1'/> </hostdev> multifunction should be on, the sound card should be function 1 and all slots and busses should be the same

Dont think so.. Your xml is wrong in the passthrough for the videocard

I think you have problems with the bios, get them from techpowerup, my own didnt work

Dont mind those

no man my bad.. but if you are usinf opencore you need to use the default ovmf files create a new vm linux for example and copy the OS sectio from there

read my first post in this same page aswering the same question as you have the same problem
