Re: [Xen-devel] Xen memory management

Thanks. My concern is that if several VMs are mapped

Someone correct me if I'm wrong, but I'm pretty sure that a DomU
kernel (If the flag is set correctly during compile time) will scrub
(i.e. "zero") RAM first before releasing it to the Xen Hypervisor.
Then hypervisor will then subsequently assign that bit of RAM to
another domain.
