I have proxmox server with ZFS file system.
I already have 128 GB of ram for host
I have 20 VMs with 30GB RAM of each which should equal to 600GB of RAM
As you can see I have shortage of RAM
what I thing is it possible to allocate part of hard drive as ram then client can see his ram as 30GB?
please note that system is working without problems but client want to see complete allocated ram

No, if you need more RAM you just need to buy more. Only thing I now be able to do that would be Intel Optane DIMMs. Its by the way not recommended to overcommit RAM and commiting 600 GB if you only have 128 GB is waaay to much.
