qemu-kvm-0.12.1.2-2.414.el6.x86_64
libvirt-0.10.2-29.el6.x86_64
How reproducible:
100%
Steps to Reproduce:
1.Prepare a virtual image XML descriptor file with qcow disk included.
# cat image.xml

<storage>
<disk id="mydisk" file="kvm-rhel6.5-x86_64-raw.img" use="system" format="raw"/>
<disk id="user" file="/var/lib/libvirt/images/user.img" use="user" format="qcow" size="1000"/>
</storage>
</image>
2. Create a virtual machine from image.xml
#virt-image image.xml
