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 packe=
ts from the guest.
Can you please let me know on how to understand instruction in the guest, w=
hich leads to the KVM exit.
From the /sys/kernel/debug/tracing/trace_pipe, I am able to see the rip whi=
ch leads to exit.
But how do I find, which instruction in the guest lead to the exit?
Thanks
Thilak Raj S
