this is not meant to to make users/customers uncertain about product quality , but whoever is deeper into using qcow2 may have a look at https://bugzilla.proxmox.com/show_bug.cgi?id=7012 , it's about a case where qcow2 performs pathologically slow and while searching for the cause, i found other interesting things, raising questions.
these findings may probably be of interest in context of other performance issues or whatever....
just by the way - how/where are YOU using qcow2 ?
do you know that "vm freezing on qcow snapshot removal" issue with qcow2 ?
furthermore i'd like to use this thread to discuss why proxmox is still not using more modern options for qcow, which apparently can dramatically improve performance , as the improvements have been around for a while ( https://bugzilla.proxmox.com/show_bug.cgi?id=1989 )
this is NOT a discussion on wether qcow2 should be used with zfs or not.
