Re: [Qemu-discuss] Booting GUI ubuntu VM on Aarch64

[Narcis Garcia]

I've run this with Qemu 2.00 in Ubuntu 14.04 succesfully:

$ qemu-system-x86_64 -cpu host -vga qxl -curses -m 8356 -enable-kvm
-boot d -drive
"file=ubuntu-gnome-15.04-desktop-amd64.iso,media=cdrom,index=0"  -vnc
0.0.0.0:52

Then to connect:
$ vncviewer MyMachine:5952
