vnmgr/vna/webapi が同一 Host に同居する場合は ZeroMQ の port は被らないように設定が必要

ip_node1 を opvbr0 に割り当てている IP に設定

OpenVNet の設定の流れ

Memo

メッセージキューに ZeroMQ を使っている Wakame-vdc だと RabbitMQ 使ってる

vnet-vna は Controller という名前のプロセスで動作している

redis の警告の対策

/var/log/redis/redis.log に下記のログが吐かれる

1

[4271] 04 Feb 09:23:33 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf
sysctl -p

:vdc_vnet_plugin

/etc/openvnet/vnmgr.conf の plugins [:vdc_vnet_plugin] は wakame-vdc との連携をさせる際に必要

bundle install 失敗
