cannot see output when installing

I'm trying to install ROS 4.3 under qemu in redhat enterprise 5.4. I'm logged in as root and these are my steps:

virt-install --connect qemu:///system -n mikrotik43 -f ~/mikrotik43.qcow2 -s 30 -r 70 --noautoconsole --os-type other --os-variant generic --accelerate --network=bridge:br0 --hvm --cdrom=/root/mikrotik-4.3.iso --nographics

I'm sure, that the installation starts sucessfully, but I don't see any text output on the minicom terminal and even in the "virsh console mikrotik43" command. The virsh command ends with "Escape character is ^]" and the console hangs up until I give CTRL+].

When I give "virt-install ... --vnc", the output on my desktop (using virt-manager linux program) is fine and I can successfully complete the installation and then even normally connect via minicom or "virsh console mikrotik43". This works perfectly.

But I want to install the mikrotik ros via text console and I don't want to use vnc. What arguments should I pass to the virt-install to run the installation in text mode? How can I do that? Or everyone uses only vnc???

The discussions on the internet said "use vnc" or "redirect the guest output to serial port" - is this possible in mikrotik installation? How?

Thank you, Tomas

virt-install --connect qemu:///system -n fedora12 -f ~/fedora12.qcow2 -s 3 -r 256 --accelerate --network=bridge:virbr0 --hvm --location http://download.fedoraproject.org/pub/fedora/linux/releases/12/Fedora/i386/os/ --nographics -x console=ttyS0

This works on Fedora. Is there any way how to do it with Mikrotik ROS?

try to compare commands you are running. Of course, one is cdrom, other is downloaded from net, but for fedora you set

-x console=ttyS0

Yes, I know, that I wrote "-x console=ttyS0" to the Fedora12, but how can I change the boot parameters for Mikrotik ROS?
I've tried to download and mount the ISO image from Download section on mikrotik.com. I copied the files and changed the file ./isolinux/isolinux.cfg to

default system

label system
        kernel linux
        append load_ramdisk=1 initrd=initrd.rgz console=ttyS0

and after this I made the boot image.

I'm just trying this

virt-install --connect qemu:///system -n mikrotik -f ~/mikrotik.qcow2 -s 1 -r 64 --os-type other --os-variant generic --accelerate --network=bridge:virbr0 --hvm --cdrom=/root/mt.iso --nographics

but the console gives no output, so either the first serial port is named differently in Mikrotik ROS or something went wronng. This is the console output:

Starting install...
Creating domain...                                                                                                                                  |    0 B     00:01     
Connected to domain mikrotik
Escape character is ^]

and nothing else outputs...

Now I've got it - I can run Mikrotik ROS in the kvm/qemu under command line only - not over VNC remotely. That was my aim. Works great!

The problem was in the ISO image packing with mkisofs. Works with "console=ttyS0" option on the kernel's parameter line.
