Description of problem: Regarding Live Storage Migration, the RHEV Admin Guide does not currently make a reference to the case of a VM being based off of a template (created as a thinly provisioned VM). When such a VM has been created from a template, the template has to be copied to the new storage domain before the VM's disk images can be moved. The template is not moved automatically. Version-Release number of selected component (if applicable): RHEV-M 3.2.2 How reproducible: Every time. Steps to Reproduce: 1. Create a VM based off of a template, selecting 'Thin' for Template Provisioning under 'Resource Allocation'. 2. Add a disk to the VM. 3. Start the VM. 4. Select/highlight the disk and click 'Move'. Actual results: Expected results: Additional info: The sequence to copy a template is something like this; Select Templates tab. Highlight template. Select Disks tab in the lower pane. Highlight disk. ‘Copy’. Copy Disk(s) window, select SD, etc.
Added topic: "Copying a Template's Virtual Hard Disk" Updated existing topic: "Moving a Virtual Machine Hard Disk Between Data Domains" Added: "If your virtual disk is attached to a virtual machine that was thinly provisioned from a template, the template's disks must be copied to any data domain that you move the virtual machine disks to." Added: See Also: 11.4.4. Copying a Template's Virtual Hard Disk
