    Question Q: Best network device model for KVM

    Hi !

    What is the best network device model for KVM in terms of reliability - virtio, e1000 or RTL8139 ?
    VM had to run as router for years in unattended mode.

    Thanks in advance for any suggestion(s).

    They all work. I've been using virtio for 8+ yrs and have used PRO/1000 (e1000) on Windows for about a year, before finally switching over to virtio devices.

    On Windows, going to virtio for disks can make fixing boot disk issues more complicated if you don't have a habit of loading special drivers for disk controllers from the Recovery Mode boot options. Usually takes me 15 minutes to figure it out before I finally remember to load virtio drivers.

    For almost all linux guests, using virtio is fully supported.
