Re: [Qemu-discuss] qemu-system-x86_64 hangs in 1024 x 768 Graphic mode when using -curses

[Kevin Wilson]

Hi, Shiyao Ma,

Thanks for the advise. I will sure try it!

I thought about the following in order to simplify it. Before giving
it a try, I want to ask your opinion if I may - do you think it will
work ?

Suppose I will download the latest qemu tar ball and compile it with
the same flags on two machines. One will be Ubuntu desktop which runs
XWindows and the second will be Ubuntu server, which does not run
XWindows.

Now, I will start the XWindows machine with the graphical mode, and I
will run from there:
qemu-img create -f qcow2 vdisk.img 10G
And then:
qemu-system-x86_64 -curses   -hda vdisk.img -cdrom
ubuntu-14.04.1-server-amd64.iso -boot d  -m 384

Now this should work I believe (maybe even without the curses).

Note that the iso is Ubuntu server image - this means that the OS that
will be installed will be in text mode, as it is a server.

Now, let's say it will complete OK and I will take vdisk.img and copy
it to the second machine, which does not run XWindows, and than try to
boot it from the terminal with something like:

qemu-system-x86_64 vdisk.img -m 384

Are there chances that this will work ?

Regards,
Kevin
