Subject: BTRFS as image store for KVM?
Date: Tue, 15 Sep 2015 23:34:04 +0200	[thread overview]
Message-ID: <55F88ECC.1040604@menke.ac> (raw)

Hi everybody,

first off, I'm not 100% sure if this is the right place to ask, so if 
it's not, I apologize and I'd appreciate a pointer in the right direction.

I want to build a virtualization server to replace my current home 
server. I'm thinking about a Debian system with libvirt/KVM. The system 
will have one or two SSDs and five harddisks with some kind of software 
RAID5 for storage. I'd like to have a filesystem with data checksums, so 
BTRFS seems like the right way to go. However, I read that BTRFS does 
not perform well as storage for KVM disk images.
(See here: http://www.linux-kvm.org/page/Tuning_KVM )

Is this still true?

I would appreciate any comments and/or tips you might have on this topic.

Is anyone using BTRFS as an image store? Are there any special settings 
I should be aware of to make it work well?

Thanks,
Gert
