Hello everyone,
It seems we reach the Linux bridge limitation on the number of interfaces in a
single bridge. Currently, we have 210 tap interface in a bridge, and we suffer
from more than 50% packet loss when we ping the IP address of the virtual
machine that uses one of the tap interfaces in

Hello everyone,
We have a physical server that hosts about 400 virtual machines. Each virtual
machine has a TAP device connected to a Linux bridge. We tried to use Linux-KVM
suggestions for QEMU networking according to this link
