Hi all,
I'm a student and am working on a personal project, I would like to receive
some feedback on implementing a memory access log
in QEMU (or in KVM, since I'm always enabling it). In particular, I want to
keep track of the guest physical pages which are accessed during a certain
interval of t
Well I'm sorry but I didn't know IDT was marked as read only by Linux. If
it is read only, how can you
register any new interrupt handler? I guess it's a way of securing stuff
against malicious attacks.
I was taking for granted that the IDT was written when registering a new
irq handler,
given that
Hello,
Have some of you successfully used the KVM_MEM_READONLY slot flag?
I'm working on a project and I'm trying to protect the guest's IDT by using
KVM, modifying kvm-all.c.
I'm able to correctly locate the IDT in the host by reading IDTR with
KVM_GET_SREGS,
translating it with KVM_TRANSLATE an

Could you also explain to me the meaning of the ram field of the KVMSlot
struct?
Best regards,
Lorenzo Susini
