Passagem de GPU única em 24.04: nada acontece ao iniciar a VM

  • 772

Sou bastante novo em tudo isso e estou tentando configurar uma VM com passagem de GPU única. Meu host está executando o Ubuntu 24.04 e estou tentando configurar uma VM do Windows 11 no Virt-Manager.

Tenho seguido principalmente o tutorial de SomeOrdinaryGamers no Youtube combinado com alguns guias para adaptá-lo ao Ubuntu.

Instalei o Win11 com sucesso em uma VM e configurei todos os ganchos, no entanto, sempre que tento inicializar a VM após configurar os ganchos, nada acontece (nenhuma mensagem de erro, nenhuma janela aparecendo e reaparecendo imediatamente e nenhum monitor ficando preto ). No entanto, na próxima vez que tento reiniciar ou desligar minha máquina host, em vez de desligá-la, primeiro ele me leva à tela de login do meu usuário (se eu fizer login, minha área de trabalho será exibida e nenhum programa será aberto). Depois de alguns segundos, não importa se eu faço login ou não, ele vai para a tela típica de desligamento do Ubuntu e não consegue desligar. Ele simplesmente entra em uma tela preta e então eu tenho que apertar o botão reset no meu caso.

Uma tentativa, minha máquina não inicializou mais depois (apenas me mostre uma tela de todos os serviços iniciados com um OK ao lado deles) e eu tive que reinstalar o Ubuntu (não é um problema - nova instalação de qualquer maneira)

Quando executo o script Iniciar sozinho, ele desconecta meu monitor com êxito.

Também não me oponho a tentar fazer isso com o Windows 10 se funcionar melhor, mas prefiro não gastar mais 6 horas esperando a instalação do Windows na VM apenas para obter o mesmo resultado.

Meu PC tem um Ryzen 9 3900X e um RTX 3080 mais 32 GB de RAM e estou instalando o Windows em uma partição de 3 TB em um disco rígido separado.

Meus Scripts atualmente são os seguintes:

/etc/libvirt/hooks/kvm.conf

  1. Você tem apenas uma GPU? Você precisaria de uma segunda GPU para o host, a menos que esteja se conectando via SSH e tenha desabilitado a GUI. Além disso, você provavelmente precisará isolar a GPU na configuração do grub2 para que o host não tente carregá-la.

    Há um bom tutorial para 22.04 (que eu acho que seria bem semelhante ao 24.04) aqui: https://mathiashueber.com/passthrough-windows-11-vm-ubuntu-22-04/

  2. Best Answer

    Finalmente consegui que isso funcionasse sozinho. Se alguém tiver esse problema, aqui está o que funcionou para mim:

    Primeiro, removi todos e quaisquer ganchos que instalei anteriormente, excluindo completamente a pasta /etc/libvirt/hooks

    Siga este guia da etapa 1 a 6. NÃO siga a etapa 7: https://gitlab.com/risingprismtv/single-gpu-passthrough/-/wikis/home (como já tinha uma VM instalada, pulei a etapa 5 )

    Next follow this Guide's automatic Install (Do not go to the manual branch. It seems outdated): https://github.com/ilayna/Single-GPU-passthrough-amd-nvidia?tab=readme-ov-file

    Next, go back to the Original Guides Step 8. You should remove the XML blocks as told by the guide (may need to enable XML editing) and also remove any other XML block if needed (Virt-manager may tell you that a specific function is not available without spice. Remove the blocks it talks about)

    Next, add the <vendor_id state='on' value='123456789123'/> and <ioapic driver='kvm'/> lines as well as the <kvm> ... </kvm> block in the XML file as explained in Step 8b from the guide (I did not do the other things in that step)

    Finally, i enabled topoext as explained in step 9 of the guide

    This got me to be able to boot the VM with a fully passed through GPU (although it took another 10 minutes or so for windows to install the drivers and detect both monitors).
