[ovirt-devel] cpuTune stats overflowing xmlrpc

[Martin Sivak]

Hi Adam,

can you identify the actual value that causes this?

The cpu code added only percentages and vcpuQuota/Period.. all those numbers are pretty low.

I do not see anything that would be more than 2^32 big (4 bilion iirc) in that code..
