Re: [ovirt-users] ovirt question

[Pavol Brilla]

​inst.stage2 = This specifies the location to fetch ONLY the installer
runtime image; packages will be ignored. ​

I think it is helping to streamline ovirt-node build, as installation part
is untouch OS and we deploy 2nd squash as image of node.

[Justin Zygmont]

Thanks, but I still don’t understand why there are 2 squash images though.

Is there any documentation around doing kickstart installs with oVirt?


Thanks,

I was able to succesfully deploy, with these steps and pxe, also taking
"inspiration" on what written at this link:
https://github.com/oVirt/ovirt-node-ng/blob/master/docs/book/install.md

note: my pxe server makes also as dhcp server and http server for install

- iso of node-ng-installer
mounted (via loop in my case) under /var/www/html/ovnode42 of pxe server

http://jenkins.ovirt.org/job/ovirt-node-ng_ovirt-4.2_build-
artifacts-el7-x86_64/lastStableBuild/artifact/exported-artifacts/

--> why not included..?

I think in theory one can downoad here also the file updates.img and it
should update the base version of the iso... TBV (not tested by me)
---> where to get the updates.img? Perhaps inside
ovirt-node-ng-image-update-x.y.z.rpm?

- inside ovnode2_stage2 created directory LiveOS and inside it created the

[ovirt-users] ovirt question

[Justin Zygmont]

I was wondering why there has to be 2 node squash images?  A LiveOS/squash.img 
and a ovirt-node-ng-image.squashfs.img in the ISO for download, and which one 
should be used?

When doing a kickstart installation I noticed it uses the Live OS image from 
the inst.stage2= and in the kickstart.cfg it would reference the other node 
image from liveimg --url

Is there any documentation around doing kickstart installs with oVirt?
