The optional <code>period</code> element specifies the enforcement
interval(unit: microseconds). Within <code>period</code>, each vcpu of
the domain will not be allowed to consume more than <code>quota</code>
worth of runtime. The value should be in range [1000, 1000000]. A period
with value 0 means no value. (NB: Only qemu driver support)

<dt><code>quota</code></dt>
<dd>
The optional <code>quota</code> element specifies the maximum allowed
bandwidth(unit: microseconds). A domain with <code>quota</code> as any
negative value indicates that the domain has infinite bandwidth, which
means that it is not bandwidth controlled. The value should be in range
[1000, 18446744073709551] or less than 0. A quota with value 0 means no
value. You can use this feature to ensure that all vcpus run at the same
speed. (NB: Only qemu driver support)
