Currently TCMalloc's default tc size is 32MB.
This causes poor performance in ceph storage.
A new ceph_tcmalloc_tc_bytes option has been added
with a default of 128MB.

128 MB is default TC size at above jewel version.
and if we don't set this config,
osd daemon will running with 32 MB.
because 32MB is default size in TCmalloc 2.4 version.
32MB and 128MB are twice the performance difference.

On RedHat libvirt is just a metapackage and it does
nothing with libvirt daemon itself if we remove it.
On Ubuntu the correct package name with libvirt daemon
is libvirt-bin.
