Memory Balloon – This counter reflects the total amount of memory the VMkernel is
effectively "borrowing" from virtual machines via the VMTools balloon driver running
inside the guest OS. Balloon driver activity indicates over-commitment of ESX host
memory. By default, the VMkernel may balloon up to 65% of a virtual machine’s
configure RAM.
I was curious if you ever thought of changing the layout
of your blog? Its very well written; I love what youve got to say.
But maybe you could a little more in the way
of content so people could connect with it better. Youve got an awful lot
of text for only having 1 or 2 images. Maybe you could space it out better?
