e1000 vs virtio

[simow]

What is the difference between E1000 and virtio? I have read that Virtio should only be used for performance in documents. then why the e1000 adapter is still in options. Which one should I use for Centos 7.8? Do I need to install a driver for vitio on default centos 7.8? What is the speed difference in the field? e1000 1 Gb virtio 10 Gb running

VirtIO is paravirtualized while e1000 is emulated. So for performance you want to use VirtIO. If required for compatibility reasons, e1000 can be used.
CentOS 7.8 comes with a kernel that has VirtIO support already integrated so you should be fine selecting VirtIO.

If I remember, e1000 is around 300mbit/s max, when you can reach 10-20gbit/s with virtio.

Hello,
I use now the virtio driver for the netwoerk card....
I get a vport0p1 device...

The speed of the network is very slow.
I use proxmox ve 6.44 and have installed the vertio drivers
