<p>Hello it's the same thing zswap.</p>
<p>The use case is to be able to put more stuff in a single host
without it need needing to swap to slow disks. You sacrifice CPU
and avoid a lot slower swap to disk.</p>

<br>
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.<br>
<br>
Has anyone tried it with oVirt Nodes or even has it been
considered as a feature to simply turn on/off ?<br>
