whether qemu-img convert will support "-s" option in the newer version

[Wei Hu]

In ubuntu os, my qemu-img version is 0.12.0 and its help message show that "qemu-img convert" command supports "-s" option, but it disappeared in qemu-img 0.12.1. However, though it disappeared, it does support in RHEL6.4, and the rpm version is qemu-img-0.12.1.2-2.355.el6.x86_64. But in RHEL6.5Beta, the same version 0.12.1, if use "qemu-img convert -s", it reports a not support '-s' option error message. The rpm version is qemu-img-0.12.1.2-2.402.el6.x86_64.
And because of this issue, the openstack "nova image-create" will raise an error. Because it uses this command with "-s" option.

Hi,

qemu 1.6.0+dfsg-2ubuntu2 certainly has the -s option. Where did you
get the '0.12.1' version which lacked the -s support?

 status: incomplete

Serge, I believe the other bug mentioned is this one:

It sounds like that is an issue in RHEL 6.5. Since the
option exists in 1.6, I don't see this being a valid bug
against qemu.

Hi Serge, you are right. I have reported this issue to redhat. They said that RHEL 6.5 have removed this option.

Looks like we need to adjust OpenStack code for the change in RHEL6.5. I see there is a bug reported here https://bugs.launchpad.net/nova/+bug/1242819 to clear up some unnecessary steps for snapshot.
