s/shares/period/
Thanks for catching that (hard to find minor mistakes like this in a big
repetitive patch). Fixed.

Is virTypedParameterAssign happy getting a NULL for the string value ?
Previously we would have set "" for the parameter rather than NULL
Yes, I specifically documented and implemented it that way:
/* Assign name, type, and the appropriately typed arg to param; in the
* case of a string, the caller is assumed to have malloc'd a string,
* or can pass NULL to have this function malloc an empty string.
* Return 0 on success, -1 after an error message on failure. */
as it made life simpler in the callers to pass NULL rather than worrying
about OOM checks.
ACK with those 2 points resolved
Thanks for the speedy review; series pushed.
