I see we use str incorrectly on more places then.. I reverted it to int (as it 
can be reported as -1 in some cases)

It does.

> Needs to be fixed here too.
Nope, not needed. The allowed values fit into int easily.

The optional period element specifies the enforcement interval(unit: 
microseconds). Within period, each vcpu of the domain will not be allowed to 
consume more than quota worth of runtime. The value should be in range [1000, 
1000000].


Line 386:         # Handling the case where quota is not set, setting to 0.
Line 387:         # According to libvirt API:"A quota with value 0 means no 
value."
Line 388:         # The value does not have to be present in some transient 
cases
Line 389:         if eInfo.get('vcpu_quota', _NO_CPU_QUOTA) != _NO_CPU_QUOTA:
Line 390:             stats['vcpuQuota'] = str(eInfo['vcpu_quota'])
> Minor nit: _NO_CPU_QUOTA is int() here. Should be harmless, however
The return value from the stats is int as well, the conversion to str is the 
last step.
Line 391: 
Line 392:         # Handling the case where period is not set, setting to 0.
Line 393:         # According to libvirt API:"A period with value 0 means no
