[ovirt-devel] cpuTune stats overflowing xmlrpc

[Martin Sivak]

Yep you are right,

The value can really get high:

quota
    The optional quota element specifies the maximum allowed bandwidth(unit: microseconds). A domain with 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 quota with value 0 means no value. You can use this feature to ensure that all vcpus run at the same speed. Only QEMU driver support since 0.9.4, LXC since 0.9.10
