Description of problem: When moving a VM to hibernate, there's no validation that the SD has enough space for the memory volumes. How reproducible: 100% Steps to Reproduce: 1. Hibernate a running VM with not enough memory in the VM's storage domain (more memory used by the VM than available on the SD). Actual results: This is not checked and should fail during operation. Expected results: CDA failure Additional info: Verify CDA failure with and without sufficient space on the SD.
verified using vt3.1 "Cannot hibernate VM. No active data Storage Domain with enough storage was found in the Data Center" 1. create VM (4096MB ram) with one disk and run it 2. check the free space on the storage domain and create floating disk with "free space"-2GB 3. hibernate the VM.
oVirt 3.5 has been released and should include the fix for this issue.
