回复：cloudstack+kvm创建快照遇到问题，求助，谢谢！
Posted by 赵涛 <zh...@qq.com>.
根据这个方法https://issues.apache.org/jira/browse/CLOUDSTACK-7300
问题应该能解决，应该是KVM宿主机qemu-img的版本问题：
Downgrounding qemu-img to CentOS 6.4 version corrects this problem. Commands to do so are below:
mkdir cloud-qemu-img
cd cloud-qemu-img
wget http://vault.centos.org/6.4/updates/x86_64/Packages/qemu-img-0.12.1.2-2.355.el6_4_4.1.x86_64.rpm
rpm2cpio qemu-img-0.12.1.2-2.355.el6_4_4.1.x86_64.rpm |cpio -idmv
cp ./usr/bin/qemu-img /usr/bin/cloud-qemu-img
