Hello is there a way to disable installing virtio drivers when converting

[gongzuokuangwang]

Hello, I am just starting to use virt-v2v.

I was trying to convert a windows ova file to libvirt.
In the process, virt-v2v was trying to install some drivers.
I kind of wish for a "vanilla" conversion, without any kind of modification of the guest.
Is it possible to disable the virtio?
I read the man page, however, I did not find any clue. Any ideas? Thanks in advance

You can simply not attach the virtio-win ISO (or make sure virtio-win is not installed), and it will do the conversion without installing virtio drivers. You will see a warning:

warning: there are no virtio drivers available for this version of Windows [...]

If you are using virt-v2v directly this is easy. Not sure about if you're using MTV or another higher-level wrapper.

This is a bit of an unusual request as without virtio, Windows guests will run very slowly.

Thank you very much for the reply.

Is there a command line option for this? I didn't find it in the man page.

I believe it would be better to have a command line option than modifying the package management system. Again, thanks!

There's no specific option but you might try playing with the VIRTIO_WIN environment variable to see if you can make it do what you want:
