[ovirt-users] ovirt question

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

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?


Thanks,



I too tried some weeks ago (4.2.1 if I remeber correctly) and was confused....
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<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_oVirt_ovirt-2Dnode-2Dng_blob_master_docs_book_install.md&d=DwMFaQ&c=Vxt5e0Osvvt2gflwSlsJ5DmPGcPvTRKLJyp031rXjhg&r=FiPhL0Cl1ymZlnTyAIIL75tE4L0reHcDdD-7wUtUGHA&m=rgnKzgcbneUduKTLB3TK11-C0nujZ9pmv5fb29w3P6M&s=7e2QHo5p940uHfpIDVGgpWYEmvdU_hv19H4TzdDSdP0&e=>
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

-under /var/www/html created directory ovnode2_stage2 containing
product.img (6k of file) downloaded here:
http://jenkins.ovirt.org/job/ovirt-node-ng_ovirt-4.2_build-artifacts-el7-x86_64/lastStableBuild/artifact/exported-artifacts/<https://urldefense.proofpoint.com/v2/url?u=http-3A__jenkins.ovirt.org_job_ovirt-2Dnode-2Dng-5Fovirt-2D4.2-5Fbuild-2Dartifacts-2Del7-2Dx86-5F64_lastStableBuild_artifact_exported-2Dartifacts_&d=DwMFaQ&c=Vxt5e0Osvvt2gflwSlsJ5DmPGcPvTRKLJyp031rXjhg&r=FiPhL0Cl1ymZlnTyAIIL75tE4L0reHcDdD-7wUtUGHA&m=rgnKzgcbneUduKTLB3TK11-C0nujZ9pmv5fb29w3P6M&s=hd2ex3r30up9YjbMif_YZQkk6ONU9wynqDjXAaxXVbE&e=>
--> 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 link
ln -sf /var/www/html/ovnode42/LiveOS/squashfs.img /var/www/html/ovnode42_stage2/LiveOS/squashfs.img


- the pxe file

It contains

- kickstart file

in /var/www/html created file ovnode42.ks
it contains

liveimg --url=http://192.168.122.1/ovnode42/ovirt-node-ng-image.squashfs.img<https://urldefense.proofpoint.com/v2/url?u=http-3A__192.168.122.1_ovnode42_ovirt-2Dnode-2Dng-2Dimage.squashfs.img&d=DwMFaQ&c=Vxt5e0Osvvt2gflwSlsJ5DmPGcPvTRKLJyp031rXjhg&r=FiPhL0Cl1ymZlnTyAIIL75tE4L0reHcDdD-7wUtUGHA&m=rgnKzgcbneUduKTLB3TK11-C0nujZ9pmv5fb29w3P6M&s=1bhy8J4Y7Il6RBc8WYH0tD_35B2H-syyR9QGJsIBaSI&e=>

# partitioning - nuke and start fresh
zerombr
clearpart --all --initlabel
autopart --type=thinp
bootloader --location=mbr

#reboot

last line left commented to cross-check before reboot

at pxe boot the graphical install comes up and completes the install without any prompt
It only asks to reboot as I commented out the line above

verified that after reboot I was able to connect to the server at https on port 9090 and getting the node dashboard
any validation comment?
HIH,
Gianluca
