# Lab 1: Unusual problem of network not showing up in c7host VM. Happened because I had not enabled a second network adapter in VMware Workstation Pro (use Team as the type).<br><br># Change all VM sizes to be at least 20GB because some (lab 2 VMs) still say 15GB and they cause problems during installation for CentOS 7.2<br><br># I think in future (based on scripting questions I gave on midterm) that we will need to add to the questions section of the labs something to do with shell scripting - even a simple walk-through. This can be incorporated into future quizzes.<br><br># VMware gets odd naming for interfaces, for example ifconfig in VMware on CentOS 7 I get this (among other network setup). The problem is they've switched from the interface naming. There is a workaround in CentOS FAQ: https://wiki.centos.org/FAQ/CentOS7<br><br># I noticed that some students have a different volume group name for centos2 than centos_centos2<br>I suspect it is that students didn't follow instructions when creating the centos2 VM by specifying the correct hostname: centos2<br>This could be corrected by including centos2 being checked for correct hostname in lab2 checking script, but not time to do that for this semester.
