[Qemu-discuss] OSX options for DHCP address for Yocto VM

[Nathan Sowatskey]

Hi

I have a Yocto VM built with a profile of qemux86-64 running successfully, sans 
networking, on OSX.

What I would like is to have a DHCP assigned address for the VM so that I can 
reach it from the host. I have tried the startup options below:

/usr/local/bin/qemu-system-x86_64 -kernel images/bzImage-qemux86-64.bin -usb 
-netdev user,id=user.0 -device usb-net,netdev=user.0 -drive 
file=images/core-image-full-cmdline-qemux86-64.ext4,if=virtio,format=raw 
-show-cursor -no-reboot -m 256 -serial mon:vc -serial null --append "vga=0 
uvesafb.mode_option=640x480-32 root=/dev/vda rw mem=256M oprofile.timer=1 
rootfstype=ext4 “

The options above, which I understood to equivalent to not specifying anything 
at all for netdev, do not give me a configured eth0. So, not what I need it 
seems.

And, with no netted options at all:

/usr/local/bin/qemu-system-x86_64 -kernel images/bzImage-qemux86-64.bin -usb 
-drive file=images/core-image-full-cmdline-qemux86-64.ext4,if=virtio,format=raw 
-show-cursor -no-reboot -m 256 -serial mon:vc -serial null --append "vga=0 
uvesafb.mode_option=640x480-32 root=/dev/vda rw mem=256M oprofile.timer=1 
rootfstype=ext4 “

The options above do give me a configured eth0, with an address taken from the 
Qemu DHCP address pool. That address, of 10.0.2.15 as it happens, is not 
reachable from the OSX host though. So, close, but no cookie yet.

Can anyone help me wth closing the gap so I can reach the VM from the OSX host 
please?

Many thanks

Nathan
