Installing Windows as VM in debian: access to peripherals


I'm experiencing some buggy performance from debian on my sound card and network cards.

If I install Windows 7 or Windows 8 as a virtual machine inside debian, will they have full access to these peripherals such as the sound and network cards, or do they rely on debian to communicate with peripherals (which means that a buggy debian driver will also impact the Windows VM)?

TIA

The hypervisor provides virtual hardware for the VM. When the OS in the VM tries to access this hardware, the hypervisor intercepts the attempt and fabricates a response. The data sent to the virtualized device is then sent to whatever real hardware it is mapped to, through the driver of the host OS. So yes, a buggy driver in the host OS can affect performance in a VM.

Which hypervisor are you using?

tnx.

I've got nothing installed for now. I want to understand if it's worth the effort to get Windows as a VM inside debian, if I'm mainly interested in circumventing buggy linux driver.

From your answer I understand this might not be worth it since the buggy drivers are still "in the loop", right?

That's correct.

If you're having problems with certain hardware, I suggest you start another thread in the debian subforum. Linux drivers usually perform quite well, so it may very well be possible to find a solution to the problems you're experiencing.

Hi,

perhaps we can help you with the "buggy" drivers. If you want to try to get these devices to play nicely with Debian, please start a new thread in the Debian forum including the following information.

- The network and sound cards do you have (output of lspci)
- The problems are you experiencing
- The version Debian are you running
- What (if anything) have you tried to get these devices working smoothly.

Cheers,

Evo2.

Evo2: I've already posted in the networking forum regarding the issues I'm experiencing with a usb dongle:
