>>I mean, no during the on-live migrate but, when start the migrate, Proxmox chack if the destination has at least igual memory available or more... 

If the target don't have enough memory, the target vm process shouldn't start. (kvm: cannot set up guest memory 'pc.ram': Cannot allocate memory)

Hi 

I mean, no during the on-live migrate but, when start the migrate, Proxmox chack if the destination has at least igual memory available or more... 
I hope make myself more clear....

Do you mean reduce the vm memory when migrating ? if yes, it's impossible. 

only way could be memory unplug, but from my test, it's not 100% perfect because of current linux limitations.

Hi... 

Perhaps my thought is no right, but even so, I will try expose it here... 
Is there a way to (in future releases, perhaps) make Proxmox more flexible when migrate a VM from one server with more memory to a server to less memory?? 

I mean, perhaps ask to set how many memory to use on the other server with less memory, if the system detect that the destination server don't have enough memory... 
Something like that... 

Regards
