Mastering Proxmox - Third Edition

Bus/Device

There are two drop-down menus available for this option. One to select the disk image bus type and the other to select the device ID.

For maximum performance, the VirtIO bus is recommended.

For a Windows VM, it is necessary to select an IDE since Windows does not have a built-in driver for VirtIO. In such cases, we can use the following steps to add VirtIO capability to a Windows VM:

1. Create the VM with IDE and install Windows as usual.
2. Add a second disk image with the VirtIO bus and reboot into Windows.
3. Download the latest VirtIO driver ISO for Windows from the following links and then load it through a virtual CD drive:
