After a hypervisor reboot some HA VMs fail to restart and encounter the error ACTION_TYPE_FAILED_VDS_VM_MEMORY

Issue

• We have configured the HA settings for 3 VMs running on a single hypervisor configured for Local Storage. When the hypervisor is unexpectedly power cycled not all of the HA configured VMs power up. After testing 5 power cycles, no more than 2 of the 3 HA VMs came back up with no user intervention.
• The ACTION_TYPE_FAILED_VDS_VM_MEMORY is observed in the /var/log/ovirt-engine/engine.log file when trying to start some of the HA VMs:

• Manually clicking on the VM and starting it works with no errors.
