On the transmission speed of different virtual machine types

[muyang_ren]

In the same Gigabit transmission network environment, the download rate of accessing the target node through LxC chicken can reach 100m, but the maximum access to the same target with KVM chicken is less than 10m. My KVM chicken network card is virtio model。
Help reasons or how to adjust the relevant configuration, thank you!

Posting the configuration of your LXC and VM would be a start? Are you sure that the virtio drivers are installed in the VM?

Thank you！
In order to test effectively, the OS of my LxC and KVM VMS are both ubuntu20.04. Virtio driver has been installed automatically during the installation of KVM type VMS, otherwise it should not be connected to the network normally. In addition, I also selected E1000 network card for comparative test. The results show that the performance of E1000 and virtio network cards is not much different, only about 10m.
