Mike, I added adminpw as a kernel option. After boot, I tried "admin/abc123" and "root/abc123" but not able to login. Any idea? David

Ok, I built an iso out of archipel and pxebooted it with stateless option. Now I got a "localhost" login prompt. Any idea what should I put in as user/pwd? David
You will need to pass a password in on the command line as well
adminpw=<hashed_password>
You can generate the hashed password using:
$ openssl passwd
Assuming the password was abc123
$ openssl passwd abc123 tKrQfufCbosr6
adminpw=tKrQfufCbosr6

Ok, I think we are on the same page now regarding stateless node. It looks like the achipel diff you just pulled in might be able to do this. But I can't quite make it out what the kernel option should be. Is it "stateless=1"?
stateless=1 or just stateless, both will work.

Perry,
I am glad you brought this up. I 'd be perfectly happy to run the root fs entirely in RAM. In fact that would be ideal for me. It's just I am not quite sure how to use pxeboot to achieve this.
I am doing a test now using the tftpboot files created from the iso. As far as I see, the kernel boot options (pxelinux.cfg/default) has:
root=live:/ovirt-node-image-2.2.2-1.1.fc16.iso
With this I can only pxeboot to the intall screen. What should I use to let the kernel mount the root fs in memory? Something like root=/dev/ram0?
David
It's not currently possible with ovirt-node. That's the whole stateless feature that we outlined. Once we actually have it implemented, it will be something along the lines of adding "stateless" to the kernel commandline.
