I’m having trouble getting sched_requirements to work with my custom attributes. what am I doing wrong here?

Here is the log entry form /var/log/one/sched.log:
Thu Apr 21 16:46:38 2016 [Z0][SCHED][D]: Match-making results for VM 241:
Cannot schedule VM. Error in SCHED_REQUIREMENTS: ‘CLUSTER_ID = 100 & !(PUBLIC_CLOUD = YES) & ( LOAD15 < MAX_CPU )’, error: syntax error, unexpected STRING, expecting INTEGER or FLOAT at line 1, columns 55:62

Thu Apr 21 16:46:38 2016 [Z0][SCHED][D]: Match-making results for VM 241:
Cannot schedule VM, there is no suitable host.

Here is my custom script that adds the LOAD-attributes:
#!/usr/bin/ruby
loadavg = File.read(’/proc/loadavg’)
loads = loadavg.scan(/\d+.\d+/)
onemin = loads[0].to_f
fivemin = loads[1].to_f
fifteenmin = loads[2].to_f
printf(“LOAD1=%d\nLOAD5=%d\nLOAD15=%d\n”, (onemin100).to_i, (fivemin100).to_i, (fifteenmin*100).to_i)

Here is the host information:

oh, i figured out that I can’t use math in the requirements… so I moved it to a script on each host and then just eval the string… SCHED_REQ… = MY_VAR = 1
