[Qemu-devel] e1000 not fully implemented

[Gadre Nayan]

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-4.4.13
Kernel: /usr/src/linux/arch/x86_64/boot/bzImage

I have built the latest qemu from source.
./configure --enable-trace-backend=ftrace --target-list=x86_64-softmmu
--enable-debug --enable-sdl --enable-kvm
make

/x86_64-softmmu/qemu-system-x86_64 -kernel ../../../boot/bzImage
-initrd initrd.img-4.4.13 -hda disk.img

where disk.img is created using "qemu-img create ubuntu.img 10G"

1. I get following error:
e1000: Writing to register at offset: 0x00002410. It is not fully implemented.
.
.
e1000: Writing to register at offset: 0x00003430. It is not fully implemented.
e1000: Writing to register at offset: 0x00010000. It is not fully implemented.

2. The QEMU screen goes pixeleted and hangs.

Am I missing certain options as inputs to qemu.
Kindly suggest.

THanks.

Have you tried giving it more memory?  (-m 1024)

Recent installers and distros may hang if there is not enough RAM.

I'd also suggest the -enable-kvm option to get better performance.
