[Qemu-devel] Need help to launch VM using QEMU command

[Koushik Dutta]

Hi ALL QEMU members,

I installed qemu utility in my host machine. I want to start Virtual
machine using qemu command.
But i facing problem like "object_new_with_type". Below i past my VM launch
script as well as error.

My host machine: Intel-X86
Script for launching VM :

T=/home/koushik/vpp/cloud_ubuntu_img
sudo qemu-system-i386  -enable-kvm -m 1024 -smp sockets=1,cpus=4,cores=2
-cpu host \
    -vga none -nographic \
    -kernel $T/vmlinuz-4.4.0-96-generic --append "console=ttyAMA0
root=/dev/vda rw"  \
    -drive file=$T/custom32.img,if=virtio,aio=threads \
    -chardev socket,id=char1,path=/tmp/sock1.sock \
    -netdev type=vhost-user,id=mynet1,chardev=char1,vhostforce\
    -device virtio-net-pci,mac=00:00:00:00:00:01,netdev=mynet1 \
    -object
memory-backend-file,id=mem,size=1024M,mem-path=/dev/hugepages,share=on \
    -numa node,memdev=mem -mem-prealloc \
    #-debugcon file:debug.log -global isa-debugcon.iobase=0x402



Bug :
(process:1285): GLib-WARNING **: gmem.c:483: custom memory allocation
vtable not supported
**
ERROR:qom/object.c:437:object_new_with_type: assertion failed: (type !=
NULL)

Please suggest me what did i wrong in this script.

Thanks & Regards,
Koushik
