The number of records that virConnectGetAllDomainStats can return per domain is currently limited to 4096. This is quite low -- for example, a single guest with ~320 disks will hit this limit. This increases the limit to make it much larger. Note that VIR_NET_MESSAGE_MAX still protects the total message size in the case where there are many domains and many disks per domain. I tested this using a guest with 500 disks with no issues. Signed-off-by: Richard W.M.
