[Xen-devel] Running ChromiumOS64 with Integrated Xen Virtualization Support as a Xen PV DomU

["Mr. Teo En Ming (Zhang Enming)" <space.time.universe@xxxxxxxxx>]

There seems to be a problem running ChromiumOS64 as a PV guest.

Convert the ChromiumOS64 vmdk image to raw harddisk image.

# qemu-img convert -f vmdk chromiumos64-xen.vmdk -O raw chromiumos64-xen.img

Start ChromiumOS64 as a Xen HVM domU.

kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 2048

name = "chromiumos64-xen-hvm"
vif = [ 'type=ioemu,mac=<MAC ADDRESS>,bridge=eth0,model=e1000' ]
acpi = 1
apic = 1
disk = [ 'file:/media/windows/chromiumos64-xen-build-enming.teo-3dec2009-0420hrs-sgt.img,hda,w' ]

device_model = 'qemu-dm'

boot="cd"
sdl=0
vnc=1
vnclisten="127.0.0.1"
vncdisplay=0
vncunused=1
vncconsole=1
vncpasswd=''

vcpus=2
# No passthrough
gfx_passthru=0

# Compulsory option. If stdvga is not set, display will be garbled.
stdvga=1

After signing in, press CTRL+ALT+T to get to the terminal.

Mount the root filesystem in read-write mode.

$ sudo mount -o remount,rw /

$ sudo mkdir -p /var/cache/apt/archives/partial

$ sudo mkdir -p /var/log/apt

Install GRUB.

$ sudo apt-get install grub

$ cd /usr/lib/grub/x86_64-pc

$ sudo cp * /boot/grub

$ sudo grub

grub> root (hd0,2)

grub> setup (hd0)

grub> quit

$ cd /boot/grub

Create the GRUB boot menu.

$ sudo vi menu.lst

default=0
timeout=30

        root (hd0,2)
        kernel /boot/vmlinuz ro root=LABEL=C-ROOT console=hvc0
        initrd /boot/initrd.img

Shutdown ChromiumOS64.

Start ChromiumOS64 as a Xen PV domU.
