1. Is the maximum no. of  vcpus in a particular guest limited to the
no. of host cpus ? (I guess not)

2. Is there any attempt made to co-schedule all of a guest's vcpus, in
order to avoid any spinlock holding problem ?

3. Are there any means to do content-based page sharing between guests
as VMware does ?

4. Does kvm makes any attempt to avoid TLB flushes while vm-exits and
vm-entries ? like Xen makes a memory hole ?
(my guess is that it doesn't needs to as kvm is mapped into a guest's
address-space and the pages are protected with the help of linux vm.
Am i right ? )


Slightly different ones,

5. How much useful is a balloon driver for kvm, which doesn't makes
any hard partitions of available physical memory between the guests ?
Shouldn't the linux VM's knowledge be superior in this case than the
guest-vm's  ?

6. What is coalesced mmio ?
