XO Load Balancer
Hi, I just read about the XO load balancer plugin and have enabled it with a density based plan. Pretty cool, it moved all of my VMs to one XCP-NG host (in a pool of 2) and powered down the 2nd host.
Am I correct that if the thresholds I specified in the density plan are exceeded for CPU utilization and/or memory, the load balancer will automatically power on my 2nd XCP-NG host and migrate some VMs to it?
Pretty cool feature!
If everything is configured correctly, yes it should.
@olivierlambert Thanks. Patches came out for XCP-NG 8 today and I powered up my 2nd XCP-NG server to apply pool patches, the load balancer promptly took it down...
Lesson learned, I guess I need to temporary disable my density policy before I power up the 2nd server!
Every HA or load balancing setup is too take it seriously. Consequences might be high, so use it only if we really know what you are doing.
