Github user ustcweizhou commented on the pull request: https://github.com/apache/cloudstack/pull/977#issuecomment-151204309 @wido now I got your concern. I will change code to enable/disable vm snapshot for kvm by a global configuration kvm.snapshot.enabled, so that someone who do not need this feature will not be impacted. It is not an big issue if we configure hypervisor URI in agent.properties, cloudstack read similar setting from the configuration file. It can be fixed easily. we have many command lines in scripts for network and hypervisor settings, or inside systemvms. Even in java side, there are many Scripts. The function runSimpleBashScriptForExitValue() can get the return value of Script, and deal with it.
