[jira] [Updated] (CLOUDSTACK-9738) Optimize vm expunge process for
instances with vm snapshots
[ https://issues.apache.org/jira/browse/CLOUDSTACK-9738?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nicolas Vazquez updated CLOUDSTACK-9738:
----------------------------------------
Description:
h2. Description
It was noticed that expunging instances with many vm snapshots took a look of time, as hypervisor received as many tasks as vm snapshots instance had, apart from the delete vm task. We propose a way to optimize this process for instances with vm snapshots by sending only one delete task to hypervisor, which will delete vm and its snapshots
h2. Use cases
- deleteVMsnapohsot-> no changes to current behavior
- destroyVM with expunge=false -> no actions to VMsnaphsot is performed at the moment. When VM cleanup thread is executed it will perform the same sequence as #3. If instance is recovered before expunged by the cleanup thread it will remain intact with VMSnapshot chain present
3. If deleteVM is called with expunge=true , then
a. Vmsnaphsot is marked with removed timestamp and state = Expunging in DB
b. VM is deleted in HW
