[Qemu-discuss] Libvirt add ftrace option

[Gadre Nayan]

Hi,

I am able to get traces from Guest kernel + QEMU + Host kernel using the
qemu -trace evetns=/tmp/events option

My complete command line is:
/home/gnayan/QEMU-devel/qemu-ubuntu/qemu/x86_64-softmmu/qemu-system-x86_64
-trace events=/home/gnayan/qemu_events -drive
file=/home/gnayan/CUSTOM_QEMU_SYSTEM/UBUNTU/ubuntu.img,if=virtio,format=raw
-drive file=/home/gnayan/CUSTOM_QEMU_SYSTEM/UBUNTU/u1.img,if=virtio,format=raw
-m 1G -net nic,model=virtio -net user -redir tcp:2222::22 -redir
udp:5050::5050 -enable-kvm

How can I get the same using libvirt based tools:

I create the domain using:

virt-install -n vm1 -r 1024 --disk
path=/home/gnayan/CUSTOM_QEMU_SYSTEM/UBUNTU/ubuntu.img,bus=virtio
--network network=default,model=virtio

Is the trace option available ?

Thanks
