[NETVIRT-176] Missing rules after OVS restart

Duplicate — Thu, 19 Oct 2017 21:28:28 +0000

Test flow:

Setup with two compute nodes
To create one vm instance on each compute
• D1
vm:10.0.123.4 DHCP: 10.0.123.2
• D2
vm:10.0.123.3
Setting the floating ip for 2nd vm instance: 10.64.112.3
Reset OVS on d1, capture rules before and after the reset;

Issue: missed rules for local group, for example DHCP & vm instance in the table=21 are missed (i.e. 10.0.0.123.4 and 10.0.123.2)
Result: no response on ping (I’ve tried to ping from d2 to 10.0.123.4 before and after reset)

Аfter initial analysis looks there is a race between the external group installation (group table) and the missing rules installation (which output to these groups) that after the restart.

The rules and log are attached.
Note: happened twice out of 10 attempts.
