hi
 In the paravirt case, guestos maintain its own mfn which need m2p and 
p2m ,or xen manage these ?
 I am confused about how does guestOS maintain its virt-to-physic and 
physic-to-mach mapping ,in the linux ,there is only v2p mapping,
 how does guestOS maintain its p2m mapping ,and when a virt address is   
put into a mmu, does cpu hardware convert virt-addr into machine address 
or guest's phyiscal address?

another one
does xen in hvm case support balloon for modifying the vm memory size or 
not?


I am confused about it

could you help me
Thanks in advance
