----------------------------------------------
Summary: Wrap qemu-img in objects instead of using simpleBashScript
Key: CLOUDSTACK-1158
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1158
Project: CloudStack
Issue Type: Improvement
Security Level: Public (Anyone can view this level - this is the default.)
Components: KVM
Affects Versions: 4.0.0
Reporter: Wido den Hollander
Fix For: 4.2.0
Currently when we are doing something with qemu-img in the KVM Agent we do
things like this:
..
String result = executeBashScript("qemu-img --help|grep convert");
..
Script.runSimpleBashScript("qemu-img convert"
..
This is not reliable and could be fixed by wrapping qemu-img like this:
QemuImg.convert(String sourceFormat, String source, String destFormat, string
dest);
This could then handle all the stuff like checking the output and more
importantly also checking the exit status of Qemu to see if everything works.
It could throw exceptions where needed so it makes life easier when doing such
operations in the KVM Agent.
Hopefully we can then also get rid of all kinds of bash scripts being called by
the KVM Agent.
