Re: vhost-net requested but could not be initialized

Here is the command that I use to launch my qemu VM:
qemu-system-x86_64 -cpu host -boot order=c -hda /root/Disks/ubuntu1.qcow2

Re: vhost-net requested but could not be initialized
Currently in the VM XML, I am passing the following command line argument
as a passthrough argument:
-netdev type=tap,id=net1,script=no,downscript=no,ifname=port3,vhost=on
-device
virtio-net-pci,netdev=net1,mac=00:00:00:00:00:01,csum=off,gso=off,guest_tso4=off,guest_tso6=off,guest_ecn=off
Is there another way to represent this in the XML file? maybe that may
solve the problem.

Libvirt adds extra parameters in domain XML
Hello,
In my C++ code, I generate my own domain XML file and I
use virDomainCreateXML or virDomainDefineXML to launch my qemu VM. However,
when I get to check which commands are sent to the qemu commandline, I find
that libvirt has added so many extra parameters to the ones I have already
set. How can I prevent libvirt from adding any extra parameters to the ones
I originally defined in the

vhost-net requested but could not be initialized
I am using a custom qemu to launch a vhost enabled VM. The qemu doesn't use
the default "/dev/vhost-net" directory as character device. Due to this I
am getting the error:
qemu-system-x86_64: -netdev
type=tap,id=net1,script=no,downscript=no,ifname=port3,vhost=on: vhost-net
requested but could not be initialized
Is there a way to tell libvirt to avoid using the default /dev/vhost-net
file?
I have tried using the pass-through arguments but libvirt still processes
the command and throws the error.

[PATCH RFC 0/4] vsock/virtio: optimizations to increase the throughput
...both give us an idea about whether the vsock layer introduces

Sure, I already did TCP tests on virtio-net + vhost, starting qemu in
this way:
$ qemu-system-x86_64 ... \
-netdev tap,id=net0,vhost=on,ifname=tap0,script=no,downscript=no \
-device virtio-net-pci,netdev=net0
I did also a test using TCP_NODELAY, just to be fair, because VSOCK
doesn't implement something like this.
In both cases I set the MTU to the maximum allowed (65520).
VSOCK TCP + virtio-net + vhost...
