Doing some testing of a new "ovs" build functionality built-in to Orabuntu-LXC
which allows Orabuntu-LXC to be used purely as a tool for testing building and
upgrading OpenvSwitch from source on RedHat-family Linux flavors and distros.
This mode of Orabuntu-LXC bypasses all the container deployment functionality
and just builds RPM for any supported version of OpenvSwitch and then installs
the RPMs, allowing Orabuntu-LXC to be used purely as an OpenvSwitch build
method development tool separate from Orabuntu-LXC's larger functionalities.
So I build OpenvSwitch 2.4.0 RPMs on Oracle Linux 6. Install them. Then I
build OpenvSwitch 2.5.0 RPM's on same host. Install them. Then I build
OpenvSwitch 2.5.9 RPMs on Oracle Linux 6 (same host) but this time run the full
Orabuntu-LXC suite and create LXC linux containers and OpenvSwitches for them
to run on, and VLAN's etc., i.e. a full container landscape, which also
upgrades OpenvSwitch by RPM from 2.5.0 to 2.5.9. Alles gut and I check:
[ubuntu@oracle61 uekulele]$ sudo ovs-vsctl --version
ovs-vsctl (Open vSwitch) 2.5.9
Compiled Oct 25 2019 14:31:55
DB Schema 7.12.1
gives 2.5.9
but when I run "ovs-vsctl show" the output gives (at the end) as shown below
and surprisingly goes all the way back to the original 2.4.0 that I installed
in Orabuntu-LXC "ovs" mode for just building and install Openvswitch (but not
creating any switches). So I'm wondering why if no switches were created
between the upgrade of OpenvSwitch from 2.4.0 --> 2.5.0 why "ovs-vsctl show"
does not at least show "2.5.0" since the switches themselves were not created
until the 3rd run when I ran the full Orabuntu-LXC installer to create a
container landscape.
[ubuntu@oracle61 uekulele]$ sudo ovs-vsctl show
(output truncated for brevity)
Port "a5"
tag: 11
Interface "a5"
error: "could not open network device a5 (No such device)"
ovs_version: "2.4.0" <-- (Shows the old 2.5.0 version here not the new
2.5.9 version)
So then I reboot the host, and check again and now alles gut again all is as it
was meant to be now.
[ubuntu@oracle61 ~]$ sudo ovs-vsctl show
