Hi, When I boot my guest kernel with KVM, the dmesg output says that: ...

Why is the Normal Zone empty?
The DMA32 zone covers the first 4GB of memory. If you have less than that (actually less than somewhat less than 4GB), nothing spills over to the normal zone.
Is it possible to have some of the guest's memory mapped in the Normal zone?
-m 8G
Is there a good reference that talks about the normal, movable, etc. memory zones?
I expect Mel Gorman's book covers it. -- I have a truly marvellous patch that fixes the bug which this signature is too narrow to contain. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
