Thanks, Could you post a bug?
The issue seems to be in
plugins/hypervisors/kvm/src/com/cloud/hypervisor/kvm/resource/LibvirtComputingResource.java
4289 private boolean isSnapshotSupported() {
4290 String result = executeBashScript("qemu-img --help|grep -E
convert|snapshot");
4291 if (result != null) {
4292 return false;
4293 } else {
4294 return true;
4295 }
4296 }
The help text differs between ubuntu and rhel:
http://manpages.ubuntu.com/manpages/natty/man1/qemu-img.1.html
https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Administration_Guide/sect-Virtualization-Tips_and_tricks-Using_qemu_img.html
Should we depend on that?
