Doc Text:	Cause: RHEL 7's Anaconda installer requires at least 768 MB of ram to complete the installation. Default ram allotment for virtual machines has always been 512 MB in Satellite. Consequence: Attempting to provision a RHEL 7 virtual machine without adjusting the default ram settings failed. Fix: Set the default ram allotment to 768 MB for RHEL 7 virtual machines. Result: Provisioning RHEL 7 virtual machines now works as expected.	Story Points:	---

Description Lukas Pramuk 2013-11-26 13:37:20 UTC

Description of problem:
Virtual Memory (in MB) default should be increased to 768MB when provisioning kvm guest using kickstartable tree of RHEL7. 
RHEL6 default is 512MB and causes anaconda to fail (OOM)

Version-Release number of selected component (if applicable):


How reproducible:
100%

Steps to Reproduce:
1. register VHost into SAT, enable Provisioning entitlement 
2. create a kickstart based on a RHEL7 kickstartable tree with virtualization type set to KVM Virtualized Guest 
3. provision kvm guest using defaults (i.e Virtual Memory se to 512MB)
4. anaconda fails during install - OOM

Actual results:
failed provisioning using the defaults (anaconda OOM)

Expected results:
successful provisioning

Additional info:
Virtual Disk Space default (3GB) is sufficient for RHEL7 - no need to change

Comment 2 Stephen Herr 2013-12-09 21:33:48 UTC

The problem is that this is not a change we can make.

The 512 MB default is in a cobbler configuration. If we updated it to 768 MB or anything else and released a new cobbler package, then the updated config file would get saved as /etc/cobbler/settings.rpmsave and not take affect unless the customer manually updates the config file and restarts cobblerd.

If a manual intervention and modifying of config files is required, then perhaps the best solution is simply to publish a knowledgebase article telling people they must modify the default ram for RHEL 7 kickstart profiles to 768 MB or higher.

We also need spacewalk commit: 4003937da4077c674d6b60b52a506da5728a37ef
