Plugins » Katello

I just bought Intel NUC with 8GB module for testing Katello and apparently when
I install CentOS 7 and keep KDump feature enabled (which is the default), some
memory is reserved for this, therefore my system reports this:

```
[root@nuc ~]# free
total used free shared buff/cache available
Mem: 7928504 427748 4026228 9076 3474528 7150332
Swap: 7812092 0 7812092
[root@nuc ~]# grep MemTotal /proc/meminfo | awk '{print $2}'
7928504
```

This patch changes the check to accept 7.9 GB as 8 GB threshold. If this is a
problem for Katello, I will rewrite the patch and change the error message to
"Minimum 8.1 GB is required" which is really what the check does. But it's
really weird requirement, I am testing with real hardware.
