--Sig_/hzMT/DWeH6RFwqqMA6OukBU Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable Hello, I discovered that virtio-net very slow with FreeBSD 12.0 Host. And with very slow I mean 16 kBit/s. I can't exclude that there is a problem in my setup. But I created two very similar setups. One with FreeBSD 11.2 and one with 12.0. The server with 11.2 has no problem. Either I do something really wrong or there is a Bug in the virtio-net. Both Servers are connected to a switch, the IPs of the VMs are in the vlan 4030. The Bhyve VMs are mangaed by vm-bhyve (master from github).=20 Bridges are created by rc.conf: # Vlans vlans_em0=3D"030" ifconfig_em0_4030=3D"mtu 1400 up" # Bridges cloned_interfaces=3D"bridge0" ifconfig_bridge0=3D"addm em0.4030 mtu 1400 up" switch definition: switch_list=3D"vm-net" type_vm-net=3D"manual" bridge_vm-net=3D"bridge0" VM config: loader=3D"bhyveload" cpu=3D7 memory=3D40G network0_type=3D"virtio-net" network0_switch=3D"vm-net" disk0_type=3D"virtio-blk" disk0_name=3D"disk0" disk0_dev=3D"sparse-zvol" vm creation: vm create -t test-host -i FreeBSD-12.0-RELEASE-amd64.raw test-example-com vm start test-example-com Network setup (on the VM): root@freebsd:~ # ifconfig vtnet0 xx.xx.xx.xx/28 mtu 1400 root@freebsd:~ # route add default yy.yy.yy.yy could someone help me to figure out if this is a Bug, and if yes where it i= s?
