Hi Marcin,
Thank you for your response.
I used engine-setup to do the configuration. Only exception is that I had to run "vdsm-tool ovn-config engine-ip local-ip" (ie. vdsm-tool ovn-config 10.0.1.101 10.0.1.21) on hypervisors.
Here is the output of requested commands:

Hi Samuli,
Let's first make sure the configuration is correct.
How did you configure the env? Did you use the automatic engine-setup
configuration?
Can you please send me the output of the following:
on engine:
ovn-sbctl show
ovn-nbctl show
on hosts:
ip addr
ovs-vsctl show
The 'vdsm-tool ovn-config' command configures the ovn controller to use the
first ip as the ovn central, and the local tunnel to use the second one.
Regards,
Marcin

be ok and it's possible to ping hosts, do dns& ntp queries and so on.Hi all,
I'm building a home lab using oVirt+GlusterFS in hyperconverged(ish) setup.
My setup consists of 2x nodes with ASRock H110M-STX motherboard, Intel
Pentium G4560 3,5 GHz CPU and 16 GB RAM. Motherboard has integrated Intel
Gigabit I219V LAN. At the moment I'm using RaspberryPi as Gluster arbiter
node. Nodes are connected to basic "desktop switch" without any management
available.
Hardware is nowhere near perfect, but it get its job done and is enough
for playing around. However I'm having problems getting OVN to work
properly and I'm clueless where to look next.
oVirt is setup like this:
oVirt engine host oe / 10.0.1.101
oVirt hypervisor host o2 / 10.0.1.18
oVirt hypervisor host o3 / 10.0.1.21
OVN network 10.0.200.0/24
When I spin up a VM in o2 and o3 with IP address in network 10.0.1.0/24
everything works fine. VMs can interact between each other without any
problems.
Problems show up when I try to use OVN based network between virtual
machines. If virtual machines are on same hypervisor then everything seems
to work ok. But if I have virtual machine on hypervisor o2 and another one
on hypervisor o3 then TCP connections doesn't work very well. UDP seems to
Problem with TCP is that for example when taking SSH connection to another
host at some point connection just hangs and most of the time it's not even
possible to even log in before connectiong hangs. If I look into tcpdump at
that point it looks like packets never reach destination. Also, if I have
multiple connections, then all of them hang at the same time.
I have tried switching off tx checksum and other similar settings, but it
didn't make any difference.
I'm suspecting that hardware is not good enough. Before investigating into
new hardware I'd like to get some confirmation that everything is setup
correctly.
When setting up oVirt/OVN I had to run following undocumented command to
get it working at all: vdsm-tool ovn-config 10.0.1.101 10.0.1.21 (oVirt
engine IP, hypervisor IP). Especially this makes me think that I have
missed some crucial part in configuration.
On oVirt engine in /var/log/openvswitch/ovsdb-server-nb.log there are
error messages:
2018-05-06T08:30:05.418Z|00913|stream_ssl|WARN|SSL_read: unexpected SSL
connection close
2018-05-06T08:30:05.418Z|00914|jsonrpc|WARN|ssl:127.0.0.1: 53152 : receive

2018-05-06T08:30:05.419Z|00915|reconnect|WARN|ssl:127.0.0.1: 53152 :
connection dropped (Protocol error)
To be honest, I'm not sure what's causing those error messages or are they
related. I found out some bug reports stating that they are not critical.
Any ideas what to do next or should I just get better hardware? :)

Samuli Heinonen
