# Windows虚拟机virtio驱动版本

[KVM/QEMU Windows guest drivers (virtio-win)](https://github.com/virtio-win/kvm-guest-drivers-windows)是 KVM/QEMU Windoes guest驱动，同时提供了paravirtual和emulated硬件。

如果需要直接安装二进制驱动程序，可以从 [Fedora Windows Virtio Drivers](https://fedoraproject.org/wiki/Windows_Virtio_Drivers)下载。

从 virtio-win-0.1.103-2 开始支持 [QEMU pvpanic](https://github.com/qemu/qemu/blob/master/docs/specs/pvpanic.txt)

## 如何检查当前已安装virtio-win版本

* 在Windows系统中找到`viostor.sys`文件（`C:\Windows\System32\drivers\viostor.sys`），然后检查`Properties > Details`版本信息

![virtio-win的viostor.sys版本](https://3334459331-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LeFI0OlHH4bg0gqJ3hR%2F-M1T9_Bfe6KWQGInkWGi%2F-M1TAEaY7Wv4mmEufYTj%2Fvirt-win_viostor.sys.png?generation=1583201772239500\&alt=media)

上述版本为 `62.61.101.58001` 则对应的`virtio-win`版本是`virtio-win-0.1.58-1.iso` ?

> 参考[how to find which virtio drivers version is installed in windows?](https://forum.proxmox.com/threads/solved-how-to-find-which-virtio-drivers-version-is-installed-in-windows.16174/)，检查当前已经安装的`virtio-win`驱动的版本第4个字段
