After that I lauch my perl program to consume RAM and stop it
[root@ovirt-dev-c7-vm1 ~]# free -m
total used free shared buff/cache available
Mem: 7820 6876 846 2 96 745
Swap: 8063 109 7954
[root@ovirt-dev-c7-vm1 ~]# free -m

Mem: 7820 188 7535 2 96 7433
Swap: 8063 109 7954
[root@ovirt-dev-c7-vm1 ~]#
On hypervisor side, RAM is not released :
[root@ovirt-dev1 ~]# free -m
total used free shared buff/cache available
Mem: 31989 8750 22657 17 581 22816

[root@ovirt-dev1 ~]# top

22525 qemu 20 0 9126664 8,0g 13664 S 1,7 25,4 0:42.57 qemu-kvm
qemu-kvm process still use 8GB RAM instead of ~300MB.
An idea ?
Thanks !
