Re: [ovirt-devel] cpuTune stats overflowing xmlrpc
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
