Hi,
I am trying to test SPDK on a Virtual Machine with NVME support. I do not
have NVME cards on the Host hence wanted to simulate the Hardware, I have
install nvmeqemu (https://github.com/nvmeqemu/nvmeqemu) for that purpose.
I installed Ubuntu 16.04 server on this, however when I use the "-smp

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_SY
Hi,
I was trying to understand the flow of packets from the Guest OS to my
NIC card, while using the Virtio paravirtualized drivers. (Qemu is not
emulating the NIC)
THis is as far as I have understood:
{
THe guest OS starts with a virtio nic:
-net nic,model=virtio -net user -redir tcp:::22
A
ilter
echo virtio_queue_rq >> /sys/kernel/debug/tracing/set_ftrace_filter
However the traces don't show a virt related event.
I launch QEMU using:
qemu-system-x86_64 -drive
file=/home/gnayan/CUSTOM_QEMU_SYSTEM/UBUNTU/ubuntu.img,if=virtio,format=raw
-m 1G -net nic,model=virtio -net u
I am unable to get the virtio related events in either the
guest or the host.
My understanding is that in the Guest OS, I will have a virtio-blk
which is the driver, the device is the virtio-transport or the
virtio-queue, then the virtio-queue will raise a kick to then dispatch
the block request t
Hi everyone,
I wanted to setup a ftrace based mechanism to understand flows within
the guest and host simultaneously.
Are there mechanisms available to get traces from guest and host and
then collate them to get a merged trace which helps to understand
exact flow of guest with host ? OR
generate a
Hi everyone,
I am trying to get my Host Ubuntu Machines kernel and initrd to run in
QEMU as well.
Basically I have Host Ubuntu 16.04, with Linux kernel 4.4.13. I
compiled the kernel (make, make modules modules_install, install
etc.).
So I have the following files:
Initrd:/boot/initrd.img-4.4
Hi,
I have recently started working on QEMU and it seems a daunting task
to say the least, hence I wanted some head-start. I have browsed the
source but I still need to bring closer some dots so I can start
working on some experimental changes. I will have to ask further
questions based on my new
