      I have a virtual machine based on KVM, which has 4 vCPUs and 8GB of RAM. When there is a lot of traffic, I experience packet loss:

      (The beginning has a lot of packet loss because I reset the machine with more power, thinking that might be the cause. However, real traffic begins at 11:40 a.m., and you can see that the latency and packet loss increase at that point).

      CPU usage is around 10%, so that shouldn't be the problem. I have disabled ‘hardware checksum offload’. There is no difference, except that CPU usage is higher.

      I don't know what else could be causing this. Many thanks in advance for your help.
