Limit Restore Impact

[adamb]

Is there anyway to limit the speed/IO of a kvm restore. We can do this for backups with vzdump.conf but it doesn't seem to work for restores.

Well I guess I will have to handle this at my storage with QOS. This is a pretty big feature that proxmox is missing and has a big impact on the enviroment.

on the CLI, you can pass the backup file to qmrestore in a rate limited fashion via stdin - maybe this is an option?

First ive heard of this. Would this be like using ionice?

you can use 'pv' or 'cstream' or the like in a pipe, and qmrestore accepts '-' as archive path to read from STDIN.
