[one-users] create image error with ceph

Tue Jun 4 23:48:30 PDT 2013

Fixed it.

I have compile the qemu-img lasted version for support rbd by hand, but 
it can't work. Got this error:

$ qemu-img convert -O rbd /var/tmp/9adcb555fee553fb1fce447d6ed0a9d4 
rbd:images/one-15
Segment fault (core dumped)

Just replace the qemu-img/qemu-kvm packages from here:

http://ceph.com/packages/qemu-kvm/x86_64/

Supported formats: raw cow qcow vdi vmdk cloop dmg bochs vpc vvfat 
qcow2 qed parallels nbd blkdebug host_cdrom host_floppy host_device file 
rbd

It works now.

Thanks George.
