Hello, We use a Mellanox ConnectX-5 card with Mellanox ASAP2 features. We use bond interface here.
When creating a new VM, there are constant errors in /openvswitch/ovs-vswitchd.log. 2019-11-11T15:54:46.937Z|00108|connmgr|INFO|br-int<->tcp:127.0.0.1:6633: 16 flow_mods in the 4 s starting 10 s ago (12 adds, 4 deletes) 2019-11-11T16:03:53.798Z|00001|dpif_netlink(handler7)|ERR|failed to offload flow: Numerical result out of range: eth51 2019-11-11T16:03:53.810Z|00002|dpif_netlink(handler7)|ERR|failed to offload flow: Numerical result out of range: eth51 2019-11-11T16:03:54.154Z|00003|dpif_netlink(handler7)|ERR|failed to offload flow: Numerical result out of range: eth51 2019-11-11T16:03:55.178Z|00004|dpif_netlink(handler7)|ERR|failed to offload flow: Numerical result out of range: eth51 root at dev-node1<https://mail.openvswitch.org/mailman/listinfo/ovs-discuss>:/usr/share/doc# service ovs-vswitchd status * ovs-vswitchd.service - Open vSwitch Forwarding Unit Loaded: loaded (/lib/systemd/system/ovs-vswitchd.service; static; vendor preset: enabled) Active: active (running) since Mon 2019-11-11 16:28:43 CET; 36min ago Process: 26869 ExecStop=/usr/share/openvswitch/scripts/ovs-ctl --no-ovsdb-server stop (code=exited, status=0/SUCCESS) Process: 26993 ExecStart=/usr/share/openvswitch/scripts/ovs-ctl --no-ovsdb-server --no-monitor --system-id=random start $OPTIONS (code=exited, Main PID: 27037 (ovs-vswitchd) Tasks: 4 (limit: 4915) CGroup: /system.slice/ovs-vswitchd.service `-27037 ovs-vswitchd unix:/var/run/openvswitch/db.sock -vconsole:emer -vsyslog:err -vfile:info --mlockall --no-chdir --log-file=/var/l Nov 11 16:28:43 dev-node1 ovs-vsctl[27057]: ovs|00001|vsctl|INFO|Called as ovs-vsctl --no-wait set Open_vSwitch . external-ids:hostname=dev-node1 Nov 11 16:28:43 dev-node1 ovs-ctl[26993]: * Enabling remote OVSDB managers Nov 11 16:28:43 dev-node1 systemd[1]: Started Open vSwitch Forwarding Unit.

The problem starts after a few successfully created VMs. Then it happens every time. Ovs-vswitchd does not crash, but the error is still there. We have hw-offload turned on root at dev-node1<https://mail.openvswitch.org/mailman/listinfo/ovs-discuss>: ~ # ovs-vsctl get Open_vSwitch. other-config {hw-offload = "true"} With hw-offload disabled, creating new instances is no problem. We use 18.04.1-Ubuntu. We have installed inux-generic-hwe-18.04-edge kernel as recommended. apt list --installed | grep linux-image linux-image-generic-hwe-18.04-edge/bionic,now 4.18.0.16.65 amd64 [installed] cat /proc/version Linux version 4.18.0-16-generic (buildd@lcy01-amd64-006) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #17~18.04.1-Ubuntu hwe-support-status - verbose Your Hardware Enablement Stack (HWE) is supported until April 2023 ovs-vswitchd --version ovs-vswitchd (Open vSwitch) 2.12.0 We've installed these packages openvswitch-common / now 2.12.0-0ubuntu1 ~ amd64 [installed, local] openvswitch-dbg / now 2.12.0-0ubuntu1 ~ amd64 [installed, local] openvswitch-switch / now 2.12.0-0ubuntu1 ~ amd64 [installed, local] python3-openvswitch / now 2.12.0-0ubuntu1 ~ cloud0 all Thank you for your help.
