Hi All,
If the host system decides that it wants to push a given page out to
swap, the host will notify the host through registered mmu notifier to
inform the guest. I am wondering if there any other situations, other
than swapping, which will trigger the mmu notifier to inform host page
change to
Hi Juan,
What's that about?

Hi all.
If the hardware does not support APIC virtualization: kvm_vcpu_kick sends an
host-IPI to the remote vcpu if that vcpu is in guest mode, a VM-exit
(exit reason: external interrupt) will be triggered due to the host-IPI.
Then on VM-entry (inject_pending_event) the guest-IPI is injected. If

Hi All,
I have a question regarding Guest TLB flush IPI. Suppose we get two
vcpus 0 and 1.
When vcpu#0 wants to invalidate the tlb entry on vcpu#1. An IPI will
be generated by lapic on vcpu#0 by writing to ICR which will cause a
vmexit.

Hi All,
I am wondering whether virtio has provided polling mode already. Instead of
sending a event from guest to host through eventfd on guest side and inject
an interrupt into guest on host side to notify each other? Could both sides
keep polling the Vring to communicate with each other?

Hi All,
I am trying to debug guest OS through qemu with kvm enabled.
Following is what I have done:
1: fire the qemu-kvm
sudo qemu-system-x86_64 -hda vdisk.img -m 4096 -smp 2 -vnc :2 -boot c -s
2: wait until login into guest OS (ubuntu 10.04)
3: fire gdb
gdb vmlinux
target remote :1234
