[ovirt-users] Using zRam with oVirt Nodes

Hello folks. On simple libvirt/KVM hosts in order to improve RAM usage and avoid swap to disk I use zRam with swap to RAM technique. So create half of amount of host memory in zRam disk divided by the number of CPU cores. Works pretty well. Has anyone tried it with oVirt Nodes or even has it been considered as a feature to simply turn on/off ? Thanks Fernando
