Subject RE: Unable to add an instance - speed=500Mhz, Ram=512 (host is in avoid set)
Date Tue, 05 Jun 2012 03:07:20 GMT
Attached is the proper grep of job-14.

In this small size instance scenario failure, is the XenServer
the system that is saying 'Hey 500Mbytes isn't enough RAM'?

I am trying to understand exactly which system is saying what
in particular is insufficient.


Regards,
Evan

The setup lacks the resources. See more detailed information inline. Btw, to capture all logs
related to vm deployment, grep by job-id should be done (in this case "grep job-14 management-server.log").

The host was put in avoid set some time before (the log fragment you've sent doesn't capture
it). The host can be put in avoid set when it doesn't have enough resources for vm start (cpu/ram).

CapacityType: 0 means RAM. When we analyze if host is capable for vm deployment, we always
make sure the total RAM (including the RAM we are allocating for the vm), doesn't exceed RAM
capacity threshold (global config variable cluster.memory.allocated.capacity.disablethreshold).

The solution will be - create the service offering with small amount of RAM/CPU (depends of
how many vms you are planning to run on your host). Or add more hosts to the Xen cluster.
