為什麼在我指定 q35 時會創建 i440fx 類型的機器，我如何讓 q35 工作？

我需要創建一個具有 Q35 機器類型的 Windows VM。然而，儘管指定了 q35，還是創建了 i440fx 機器。

創建與：

sudo virt-install \
--name wintest \
--boot uefi \
--ram 32768 \
--graphics spice \
--machine q35 \
--features kvm_hidden=on \
--hostdev 0a:00.0,address.type=pci,address.multifunction=on \
--machine pc \
--vcpus 4 \
--os-type windows \
--os-variant win10 \
--network bridge=br0 \
--console pty,target_type=serial \
--disk /home/boss/Downloads/Win10_1809Oct_English_x64.iso,device=cdrom \
--disk /home/boss/Downloads/virtio-win-0.1.164.iso,device=cdrom \
--disk path=/home/boss/testVM/wintest.img,bus=virtio,size=60

在創建過程中命令行出現了一些錯誤，但我認為它們可能無關緊要，但在這裡它們是：

因為你不小心指定--machine了兩次。

--machine q35 \
--features kvm_hidden=on \
--hostdev 0a:00.0,address.type=pci,address.multifunction=on \
--machine pc \

刪除包含--machine pc \.
