I did fix a paragraph code, can Resize. but it's not apply when running, must shutdown it applies
version old I fix success. after update version I can't fix it's :(

you cannot change maximum allocation of memory while running.
but you should change current allocation of memory while instance is running.

which one you cannot change?

[letran3691]

I can't change any option at tab #RESIZE while VM running. when just shutdown VM, changes apply to VM

i can work it on. but i need time..

[letran3691]

Yes. Please help me!!!

When VM shutdown. I set "Current allocation (MB) 2G" and "Maximum allocation (MB) 8G "

But when I run VM then part "Current allocation " auto received "Maximum allocation 8G"

I don't know bug where

there is nothing change on resize code by me. but as you said it happens as described.
may be it was broken before.. i will check it.

i think it is default behaviour of KVM guests. While vm is starting it set maxiumu allocation. After boot up of instance, memory ballooning mechanism activates. Then if it is possible, it shrinks to current allocation.

to sum up, there is not any bug. but it is a feature :)

Yes. I check again and accurate as you say. But i can't #resize current memory while VM running. I did test Increase RAM while VM running with command "virsh setmem php-fpm_test 2049M --live", it's works normally.
Please help me can #resize while VM running. Please!!!
