Comment 5 for bug 1341486

Aleksandr Didenko (adidenko) logs:

Astute got message where new kernel params not insert in required filed. Information which applied for provisioning state should contain in provisioning state, but:

2014-07-15T13:43:59 debug: [374] Process message from worker queue: ...

    \"pm_data\": {\"kernel_params\": \"console=ttyS0,9600 console=tty0 rootdelay=90 nomodeset\"

but should

    \"pm_data\": {\"kernel_params\": \"console=ttyS0,9600 console=tty0 rootdelay=90 nomodeset intel_iommu=on\"

also this param showed in deployment section:

  \"metadata\": {<...> \"kernel_params\": {\"kernel\": \"console=ttyS0,9600 console=tty0 rootdelay=90 nomodeset intel_iommu=on\"}

this section correct.

For some reason Nailgun do no send data correctly for this case.

This can be proven by Nailgun logs to. If we check Nailgun app.logs:

Aleksandr, do you use web interface or cli to deploy this cluster?

Also i could not reproduce it in 5.1 ISO #343.
