Hi,
(BTW, I noticed that Xenner does not limit guest segments like Xen does. Does it mean the guest can overwrite the Xenner kernel and effectively run ring0?)
Yes. The guest also can modify page tables as it pleases. It is the vmx/svm container which protects the host, not the xenner kernel.
cheers, Gerd
