Starting oVirt 4.2.4 (also in 4.2.5 and maybe in 4.2.3) I am facing
some sort of memory leak. The memory usage on the hosts keep
increasing till it reaches somewhere around 97%. Putting the host in
maintenance and back resolves it. The memory usage by the qemu-kvm
processes is way above the defined VM memory for instance below is the
memory usage of a VM:

Sounds to me as the recent gluster memory leak which is fixed at version 3.12.13.

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+
COMMAND
12271 qemu 20 0 35.4g 30.9g 8144 S 13.3 49.3
9433:15 qemu-kvm

The VM memory settings are:

Defined Memory: 8192 MB
Physical Memory Guaranteed: 5461 MB

This is for a 3 node hyperconverged cluster running on latest oVirt Node 4.2.5.
