[Qemu-devel] Debugging QEMU Exits

[Thilak Raj Surendrababu]

Hi All,

I am new to qemu, I am trying to understand virtio_net.

I am seeing a lot of KVM_EXITS due to IO_INSTRUCTION, when I transmit packets from the guest.

Can you please let me know on how to understand instruction in the guest, which leads to the KVM exit.

From the /sys/kernel/debug/tracing/trace_pipe, I am able to see the rip which leads to exit.

But how do I find, which instruction in the guest lead to the exit?

 

Thanks
