Each day since install just after 9:00am a log entry appears stating:

pve1 kernel: EXT4-fs (dm-1): Unaligned AIO/DIO on inode 36831235 by kvm; performance will be poor.

I am not seeing any noticable performance hit. A quick google search showed a few posts here and there where people are getting the same message. Only one post I found was the person able to resolve it by setting the VM config to "Use host I/O cache" enabled. I believe they were using Virtualbox. I do not see a setting to change this on Proxmox. I guess I am wonder first if this is somehow adversely affecting my VM and/or what needs to be done to fix it.

TIA

I also noticed this on my machine. Does anyone have any recommendations on how to work around this problem?
