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.
