changing memory size with virsh setmem - results only visible in domain, not on host

[Lentes, Bernd]

Hi,

i have a Linux domain (Ubuntu 14.04) where we like to be able to change the amount of usable memory.
We have a balloon device and statistics are switched in 5 sec. rhythm.
The domain shows very quickly changes (following top) when we change the memory size with setmem, but the host does not show changes in the use 
of memory for the respective domain.
Is that expected behavior ?

Host is SLES 12 SP4, libvirt is 4.0.0-8.15.2
