Hi there, i would like to ask you how to configure transer speed of VM migration between hosts in claster.

I have for e.g. 2 hosts in claster and i want to migrate VM between them - when i try to do it, it copy VHD with full speed and this is big issue for me so i am looking for way to control it.

I was looking for it a while already and datacenter.cfg entry that controls Cstream is not working on transfer speed. It works when i restore backup - thats fine but i am looking for this specific way to lower transfer speed of VM migration. Can be anything - disk read or network speed blockade.

Please let me know how - if possible - i can control data stream.
 
please check:

> man datacenter.cfg
 
Hey i know it - it works only with restore from backup - doesnt affect migration speed at all.
 
pls post your:

> cat /etc/pve/datacenter.cfg
 
Here you go:

keyboard: pl

migration: insecure,network=192.168.30.0/24

bwlimit: clone=10000,default=30000,migration=30000,move=10000,restore=50000
 
Hey - any ideas what to do with that? Maybe it will be fixed with new patches? Can you confirm please?
 
Hi guys anything new regarding that? This is big issue for my company - let me know please.
