URL: https://github.com/apache/cloudstack/issues/10626
### problem
Unable to start a vm which has a iso after vmware storage drs get's
triggered in datastore cluster
### versions
Cloudstack version 4.18,4.19,4.20
Vmware 8.0
### The steps to reproduce the bug
This issue was also reported before in #7536
1. Have a Cloudstack environment with Vmware 8.0 and datastore cluster and
vsphere storage drs enabled
2. Deploy a vm with a iso image
Before drs
mysql> select name,path,pool_id,chain_info from volumes where instance_id=60
\G;
*************************** 1. row ***************************
name: ROOT-60
path: ROOT-60
pool_id: 12

i-2-60-VM/6e5a103aa6a541218edae99ab0883a17.vmdk"]}

3. Stop the vm
4. Trigger a vsphere storage drs on one of the datastore cluster ( this can
done filling up a datastore)
5. Start the vm > vm unable to start
