Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=812295 According to QEMU docs, the '-m' option for specifying RAM is by default in MiB, and a suffix of "M" or "G" may be passed for values in MiB and GiB respectively. This commit adds support and a test for the same. Also, change the type of mem from int to unsigned long long as per convention and also because virDomainDefSetMemoryTotal expects the latter.
