[libvirt-users] Can I run a KVM guest with a btrfs subvolume as file system?

[Thomas Koch]

Hi,	

I want to run a virtualized Debian stable KVM guest on a Debian stable host 
(to run untrusted stuff like Skype, Flash or eclipse with third-party plugins). 
Naturally host and guest will have many files in common and it would be nice to 
make us of btrfs deduplication.

Now I found "direct kernel boot" but I could not find any documentation about 
it. Does it allow me to hand a btrfs subvolume of the host file system to the 
guest and the guest uses this subvolume as its own file system?

I already asked this question here:
