Hi all,
Getting strange numbers from the virsh memtune command on RHEL 6. (git head compiled, rather than RHEL 6 packages)
virsh # list Id Name State ---------------------------------- 4 Fedora_14_x64 running
virsh # memtune Fedora_14_x64 hard_limit : 9007199254740991 soft_limit : 9007199254740991 swap_hard_limit: 9007199254740991
Those numbers are supposed to be kilobytes, but the host box itself only has 12GB ram.
Bug?
Smells like a case of mistakenly treating either -1 or INT64_MAX as a valid value (that integer is 0x1f_ffff_ffff_ffff, which happens to be UINT64_MAX>>11 or INT64_MAX>>10), rather than recognizing it as meaning unlimited or undeterminable. If unlimited is the intended meaning, virsh can probably be taught to display it differently, perhaps by also referencing the host's limits.
Yeah, that sounds like it might be the cause. Nikunj, is this your kind of thing to look at bug wise? Regards and best wishes, Justin Clift
