[Luc Pierard de Maujouy <luc_pierard_de_maujouy@xxxxxxxx>]

My apologize for been to late for subscription confirmation.

Resubmitting.

Env : xen 4.5 + kernel 4.0.5 + xl stack, working dom0/domU.
Level : Quite critical despite integration env as using source distro
(gentoo)

tmem is on xen command line, and reported in xl dmesg.
tmem module in loaded via init script (open-rc).
tmem has been added at the end of the kernel command line, though syntax
may be wrong.

ballooning on in dom0 cfg file.
maxmem is defined in domU cfg file.
maxmem>memory.

RAM can be manually redistributed beetween dom0 & domU via mem-set command.

When domU is forced to require more RAM than currently reported as
available via its top command, domU RAM is not automatically resized.

domU is expected to request dom0 for additionnal RAM before starting to
use swap.

Is ballooning feature misunderstood should misconfiguration be
suspected, what should be investigated?

Thks 4 ur attention, interest & support.
