Hello Mice, Thanks for this feature! After reading your document, I have a couple of questions:
Under the limitations section, can you please elaborate, in general, why those limitations arise - is it because they are not implemented (in phase 1, for example due to lack of time etc.) or they don’t make sense Specifically, the limitation " VM's service offering is not allowed to change if there are VM snapshots " - I wonder if we should allow this with a warning that the existing snapshots are invalidated (for example) Also, the limitation " Volume snapshot operations are mutually exclusive to VM snapshot operation " - why? Thank you!

I have been busy recently and haven’t updated this for awhile. Yesterday I re-created vm-snapshot branch based on 4.0 branch and submitted refactorred codes with KVM support. Now the major parts have been done, and because this touches CS core, I would like to welcome any suggestion, design/code review, tests and feedbacks of all forms. [Document] For a complete updated spec/design document, please see https://cwiki.apache.org/confluence/display/CLOUDSTACK/VM+Snapshots [Progress] (tested with simple scenario) Xenserver Free/Enterprise support VMware support KVM support UI [TBD] Resource Limit VM snapshot allocation size stat Usage [How to test] 1.please notice KVM needs a modified libvirt.jar (thanks Wido for providing it), to make KVM VM snapshot work properly, it is required to replace the old libvirt-0.4.9.jar with this one. http://people.apache.org/~mice/libvirt-0.4.9.jar 2.to test VMware support, apply Rohit’s 4.0 nonoss patch before compile/build http://bhaisaab.org/patches/cloudstack/0001-BUILD-Make-CloudStack-buildable-with-nonoss-libs.patch http://bhaisaab.org/patches/cloudstack/0002-BUILD-nonoss-libs-for-CloudStack.patch 3.use Ant/Maven to build/debug, same with 4.0.
