[one-users] Problems with scheduling VMs / Bug in Scheduler.cc

[Ruben S. Montero]

Hi Niraj,

The host->match() function sets the matched variable to true or false 
depending on the expression. The "rc" value returned by host->match() is used 
to check whether an error (i.e. syntax) is found while evaluating the 
expression. So rc==0 does not imply a matched resource.

Could you send us the REQUIREMENTS that you are using, and the 'onehost show'
output for a resource that you expect that would match.

Cheers

Ruben
