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.
How are you looking at it from the host? From the memory-related values in 'virsh dominfo' or 'virsh dumpxml'? Is the host KVM or Xen?
Is that expected behavior ? Host is SLES 12 SP4, libvirt is 4.0.0-8.15.2
There was a Xen bug along these lines, fixed by commit 11c8aca9. I've verified your version of libvirt contains that fix.
