Thanks for the quick response.  A few more questions about types.db:

The data we collect in libvirt comes from Xen, and it includes the CPU 
time used in nanoseconds as a 64 bit signed quantity.  I have no idea 
how accurate this is, but that's the data we report.  Should I define a 
new type (eg. 'virt_cpu_time_ns') setting the max value to whatever 
2^63-1 is?  Or would it be preferable to divide through, eg. to convert 
to us, ms, or even seconds?  Can I pass float values?

Rich.
