global_period
+
+ The optional global_period element specifies the + enforcement CFS scheduler interval (unit: microseconds) for the whole + domain in contrast with period which enforces the interval + per vCPU.

global_quota
+
+ The optional global_quota element specifies the maximum + allowed bandwidth (unit: microseconds) within a period for the whole + domain. A domain with global_quota 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 global_quota + with value 0 means no value. + Only QEMU driver support since 1.3.3 +
