# POC for: https://github.com/chef/chef-server/issues/718

# Demonstration of a bug where a node is incorrectly indexed as having a role that it does not.
#
# 1. chef-expander munges and flattens the node hash
#
# 2. if the node has "role" as a nested keys, it will be promoted and merged with the top

https://bugzilla.redhat.com/show_bug.cgi?id=1013758

This function is to guess the correct limit for maximal memory
usage by qemu for given domain. This can never be guessed

Subject: [PATCH] qemu: Relax hard RSS limit

https://bugzilla.redhat.com/show_bug.cgi?id=891653

Currently, if there's no hard memory limit defined for a domain,
libvirt tries to calculate one, based on domain definition and magic

# Optimal bloom filter size and number of hashes

# Tips:
# 1. One byte per item in the input set gives about a 2% false positive rate.
# 2. The optimal number of hash functions is ~0.7x the number of bits per item.
# 3. The number of hashes dominates performance.

# Expected number of items in the collection
# n = (m * ln(2))/k;
n = 300_000

# Description:
#
# Quick hack to grant a user the privileges necessary to login to the Dell DRAC web management interface.
#
# This is a workaround for a bug where a user created in IPMI can't login to the Dell DRAC web management portal.
# The user would be denied with error: Login failed. User does not have 'Login to Dell BMC' privilege.
#
# We assume that the default user and password are still enabled (root:root).
