[pve-devel] [PATCH qemu-server] fix #4249: make qemu_img_convert respect bwlimit

Leo Nunner l.nunner at proxmox.com
Fri Sep 16 13:47:41 CEST 2022


Previously, cloning a stopped VM didn't respect bwlimit. Passing the -r
(ratelimit) parameter to qemu-img convert fixes this issue.

With qemu_img_convert getting a parameter for bwlimit, would it maybe
also make sense to apply the migration limit inside ImportDisk? I'm not
quite sure if this falls under that category though.
