sadhu suresh commented on CLOUDSTACK-5393:
------------------------------------------
not seen this issue in 4.3 recent builds(last Friday pulled the code and tested
on dev setup) ,able to create snapshot on root volume successfully on 4.3
branch.will check on 4.2 branch
cenos6.2(KVM),4.3
primary :nfs
1) Created advanced zone in KVM
2) Deployed VM, enabled the kvm snaphot option in global configuration
&restart the MS
3 ) Once MS is up,Stop the running VM
4 ) Create snapshot from root volume
snapshot was successful.
