I looking for some experience sharing from those who also run OpenBSD
inside KVM on Linux.
I was running 5.2 and now 6.2 inside KVM on a Linux wheezy host with 3.2
kernel.
This system was used as an all in one Zabbix monitoring server, which
included the full stack required to run a central monitoring server:
-Lighttpd
-Zabbix Server
-Zabbix Agent
-Mysql Server
-SNMP utils
First it was using Zabbix 2.x then I have upgraded it to the 3.x series.
The zabbix server was regularily crashing or stopped logging to the DB
and needed to be restarted.
If not that then the db and page load was terribly slow even on LAN and
I only had <15 clients on this server. I started moving the components
off one by one, at the end only the zabbix server engine left on the vm
even that sometimes just stuck and stopped sending data to a standalone
other linux mysql vm. Then I gave up, I recreated the whole environment
with the same Zabbix version on an all in one Debian 9 vm and since then
it runs flawlessly. Another issue was that I kept getting dropped packet
entries in my pflog on the enabled ports (seems like broken
connections).
Anyway my point now is not to configure another Zabbix but another
enterprise software suite (Pydio) with PHP 7.x on OpenBSD 6.3 in the
same KVM environment.
This would include:
-Lighttpd
-php7.x and some modules
-needs cifs mount on one part of the webhosting from an external windows
server
-pydio cifs storage connection to external windows server
-postfix/dovecot server
Were there any improvements made in the 6.3 virtualization code that
would provide me with a brighter outlook? Did anyone run into similar
performance and app crash issues on OBSD in KVM?
