Hi all, One quick question about image format 1 & 2 :
I've got a img.qcow2 and I want to convert it : The first solution is qemu-img convert -f qcow2 -O rbd img.qcow2 rbd:/mypool/myimage As far as I understood It will converted into format 1 which is the default one so I won't be able to clone my image. Second solution is to import it directly into format 2 : Rbd import -image-format 2 img.qcow2 mypool/myimage But in this case, when I start my VM, my vm / filesystem turns readonly with many buffer IO error on dm-0. I'm running Ubuntu 14.04 for both kvm host and VMs so kernel version is 3.13.0-30 Any idea ? Thx
