The allocation shrinks by = 1MiB every apx. 5 seconds now, and it seems to be going until the target set. I guess dev.vtballoon.0.current and dev.vtballoon.0.desired are in some oth= er unit than KiB.. it's moving in steps of 256 per time virt-manager say it has adjusted the current allocation with 1MiB, pointing me to it being in 4k pa= ges? Since your code has #define VTBALLOON_PAGES_PER_REQUEST 256 I guess the reasoning is sound.. No idea why it only request changes once every 5 seconds, or thereabouts, b= ut at least it tries to work now:) --=20 You are receiving this mail because: You are the assignee for the bug.=
