Re: [Users] How to pxeboot ovrit node into memory automatically?

Hi Fabian, =20 I booted the new node stateless. But how can connect to it from ovirt engine cli? The cli asks for three things: URL, user name and password. I am not sure how to put them on the kernel boot option line. =20 David =20 =20 =20

But please note that you will have to approve the Node in Engine after each reboot if you use the stateless feature. This bug [2] might also tackle the problem of a stateless Node. =20 - fabian =20 -- [1] http://resources.ovirt.org/releases/3.3/iso/ovirt-node-iso-3.0.3-1.1.vdsm=
