> I am using KVM and I found a fatal, unsurmountable issue with Windows Virtual

> Virtual machine, the whole amount of memory is taken from the host, without
> considering that only about 350 Mb of the total is actually being used. This is
> insane. I opened a support ticket with Red Hat, and they claim that Windows
> zeros out all memory and that by doing so, it appears to be in use. So they
> laughed at me. But, hey, I replied, Vmware has that feature working fine since
> years ago. In fact, I checked on my own Vsphere 4.1 servers and the windows
> machines show a very large difference between the memory assigned,
> nominally, to the virtual machine and the actual memory used by it in the host.
> So, if they solved t, why Red Hat claims that there is no solution?
> Any idea?
