Hello, I'm running 4 virtual machines on one host, connected by a network bridge on the host (IP 192.168.0.1). All TAP devices get added to that bridge when starting the vm: brctl show bridge name bridge id STP enabled interfaces br0 8000.52fd3fbd954e no tap01 tap02 tap03 tap04 I use virtio networking (but tried the e1000 driver, too). The vms have static IPs 192.168.0.250 - 253 with 192.168.0.1 as the gateway. Connecting from the host to the machines and from the machines to the internet works just fine. The problem lies in connecting from one machine to another. There is a 30 seconds delay until the connection gets established, I tried ssh, http and mysql. After the connection is there, the speed seems to be normal. Any hints would be appreciated.
