[-- Attachment #1 --] 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). Bridges are created by rc.conf: # Vlans vlans_em0="030" ifconfig_em0_4030="mtu 1400 up" # Bridges cloned_interfaces="bridge0" ifconfig_bridge0="addm em0.4030 mtu 1400 up" switch definition: switch_list="vm-net" type_vm-net="manual" bridge_vm-net="bridge0" VM config: loader="bhyveload" cpu=7 memory=40G network0_type="virtio-net" network0_switch="vm-net" disk0_type="virtio-blk" disk0_name="disk0" disk0_dev="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 is? Thanks Ole [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEE60BGd7KVfL83NXCUJZaRRqjklFAFAlxZmCIACgkQJZaRRqjk lFACnhAArkQExBee83Bg6bTIbb6snrc4GATOURr/2Om2ueU8uUAJWl4olV51cKC+ zCB5KoH0DsjTJzirlnk69L7alZVcrYY/o+QEgou/3esyQ5SHHexxcnR2PN5fP4OT 9yywTNKgrnzkJZvTpxAvQVK/xsTUF33aVj+ZPfCYc4RCEyZ+1yXAJNML9bad5fUf dmqskT4mtU7TfzXxq2uU5hlsUaoBNMSHkUnVCHVEDEsm8OucLl6eKSoFJHfJp3MW SNdNuO4Sn3oiRBXZ+X2uiHQqnu+wbhmjvw3JUTOJbZ30xI86oRVBY2AK4QUkYvHn ruHjIDVLU2HZn6kozeQSDM9j0SSdNy0EXDy9IId3GIz82+LiSFjbF2/6NkWlD4ym Lnzv3Abzz9iLz4B+npTriQ2Abh6u5O5FVCT0VJkbSKM76+qNc4JycnQ7K5iG5Gln uV7oBIGAMEYHgNfOdCPNZsGtfiWjwNyP+JoEdkj8eHceJfqv3Xo4C26DVpYvOLbT XpiKUwAAL5vkgCzVz1hPgvgJL2T+wkRsnav93+0S20YkBF8i+tTkhsUjciI6yPZ1 lZM//JTEGqmBOiM1QXxYZ7RrrHs/WqMOFieVBXNZcfu+QkqNAoCLjtdq29xNDZvH qPSMnqj9Noe7xgEbUbqfFq4iadbZ4qAm0Zn0xEAngFFPpzPdS0Y= =ztLx -----END PGP SIGNATURE-----help
