In the 404bac14 the @tmp variable was introduced. It's purpose is to
avoid typecasting when parsing --pagesize argument. However, if the

bogus virNodeGetFreePages() API call:
virsh freepages --cellno 2
error: Failed to open file '/sys/devices/system/node/node2/hugepages/hugepages-4294967295kB/free_hugepages': No such file or directory
