Subject [jira] [Resolved] (CLOUDSTACK-5065) KVM snapshot doesn't take VM snapshot if the VM is running
Date Wed, 06 Nov 2013 23:37:17 GMT

     [ https://issues.apache.org/jira/browse/CLOUDSTACK-5065?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

edison su resolved CLOUDSTACK-5065.
-----------------------------------

    Resolution: Fixed

How to verify the issue:
Without the fix, on the kvm host, it will call managesnapshot.sh to take snapshot if the primary
storage is NFS. 
With the fix: it will call libvirt's api to create snapshot, you will see log message s, like:
<domainsnapshot>, in agent.log

{
> Right now, only primary storage type is filesystem(a.k.a local storage), then take vm
snapshot, otherwise, always take volume snapshot, which is not working for the default kvm
binary.
