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
