[ovs-discuss] Inserting and using the compiled OVS kernel modules

[Levente Csikor]

Yes, I thought so, however I don't see anything:

# modprobe openvswitch
# dmesg |tail -n 8
[250423.894258] PKCS#7 signature not signed with a trusted key
[250423.894271] Spectre V2 : System may be vulnerable to spectre v2
[250423.894273] openvswitch: loading module not compiled with retpoline
compiler.
[250423.896970] openvswitch: Open vSwitch switching datapath 2.10.0
[250423.897064] openvswitch: LISP tunneling driver
[250423.897064] GRE over IPv4 demultiplexor driver
[250423.898141] openvswitch: GRE over IPv4 tunneling driver
[250423.898488] openvswitch: GRE over IPv6 tunneling driver
# lsmod |grep openv
#

I have never encountered such a thing. When I used insmod, at least the
module itself was definitely loaded.
Any other thoughts on tracing what is happening and why the module is
not loaded?

Cheers,
levi
