Hi Mice,
Thanks for the doc. I have couple of questions:
1. Do you set a upper limit on how many VM snapshots can be created on a VM /
cluster?
2. If we have 3 vm snapshots,
A
|
B
\
C where A is the parent of B and B is parent of C.
If we remove B, do we update the parent snapshot for C?
3. between B and C, there are some disks removed from the VM; we take
snapshot C.
When we want to revert back to snapshot B, how do you handle the disks missing?
Thanks,
-Fang

Subject: VM Snapshot progress update
Hi, Folks,
Sorry for the late update. 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.
Regards
Mice
