==== VirtualBox running CentOS 7 Notes ====
**April 2020 - Upgrade to CentOS 7.8:**
Upgrade worked with no issues
**September 2019 - Upgrade to CentOS 7.7:**
Best practice is to clone a VM before upgrading so you have a clean starting point.
Got these errors upon trying to upgrade:

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
Solution:
# yum remove vlc
Then [[https://linuxize.com/post/how-to-install-vlc-on-centos-7/|Install VLC]]
Update hostname to centos7.7
Then, test VM upgrade from CentOS 7.6 to 7.7 worked OK and got full-screen graphics with Guest Additions v 6.0.10. 2 other VMs upgraded OK, but Guest Additions v6.0.12 will not install properly. Newest kernel is kernel-3.10.0-1062.1.1.el7.x86_64 but had to boot into 3.10.0-957.27.2.el7.x86_64 to get full screen display to work.
Problems:
* Windows TAT is not accessible graphically - even booting into old kernel gives non-usable graphical screen
* Work VM needs to boot into older kernel to get graphics to display
* python3 will not upgrade with the IUS repository enabled
* MATE desktop environment has double launchers
* Run: mate-panel --reset
* Then manually customize panel with launchers
* Bug with xfreerdp where CTRL-ALT-ENTER will reset X after it becomes full screen (can't toggle back and forth)
* Workaround is to use 'rdesktop' instead
Guest Additions troubleshooting:
* Open ticket with VirtualBox forums
* Downgrade Virtual Box from 6.0.12 to 6.0.10
* On test VM with GA 6.0.12, see if the hardware acceleration settings need to be changed per error message that pops up (should not need changing as it will affect VirtualBox 6.1 branch)
* Search forums for error "Building the main Guest Additions 6.0.12 module for kernel 3.10.0-1062.1.1.el7.x86_64."
* Looks like 6.0.13 is a test build and 6.0.14 will have permanent fix
* Could try installing from [[https://www.virtualbox.org/wiki/Testbuilds|VirtualBox test builds]]
* This test build does work
Python3 fix to use EPEL instead of IUS repo:
# yum remove python36u
# yum remove ius-release
# yum install python3
# yum install python3-devel
**December 2018 - Upgrade to CentOS 7.6:**

* An option may be to use [[https://www.tecmint.com/install-upgrade-kernel-version-in-centos-7/|Kernel version 4]])
* Then install Kernel headers/tools using [[https://qiita.com/tkprof/items/2ec4ed58790efba3778d|this link]]
* Remember to update kernel-tools-lib, kernel-doc, kernel-headers, kernel-devel using the swap command in the 2nd link above

**September 2017 - Upgrade to CentOS 7.4:**
Best practice is to clone a VM before upgrading so you have a clean starting point.
Right before upgrading to v7.4 I got an error due to a conflict between gstreamer1-plugins-base-1.10.4-1.el7.x86_64 and gstreamer1-plugins-bad-free-1.4.5-6.el7_3.x86_64. This seemed to be caused by the "totem" application but it was resolved in CentOS 7.4. I found a temporary workaround in 7.3 was to remove the RPM gstreamer1-plugins-bad-free which allowed other packages to update:
# yum remove gstreamer1-plugins-bad-free
However, when CentOS 7.4 became available I got another error:

Removing this package allowed the upgrade to proceed:

After I updated to CentOS 7.4 I was able to reinstall totem without any issues.
VLC also installs OK and it uses the [[https://wiki.centos.org/TipsAndTricks/MultimediaOnCentOS7|Nux Desktop]] repository.
An updated mate-themes RPM was released to fix badly-formatted pull-down menus (ex. mate-terminal).
Mutt stopped sending emails on cron and it was reported on [[https://stackoverflow.com/questions/46266841/mutt-returns-error-from-cmd-line-bad-idn-in-from|Stack Overflow]]:
Bad IDN in "from": 'machine_name'
The RHEL 7.4 package is mutt-1.5.21-27.el7.x86_64 (in CentOS 7.3 it was mutt-1.5.21-26.el7.x86_64). Downloaded and installed mutt-1.6.2-1.fc22.x86_64.rpm from [[ftp://rpmfind.net/linux/fedora/linux/updates/testing/22/x86_64/m/mutt-1.6.2-1.fc22.x86_64.rpm|rpmfind.net]] as a workaround.
On the host machine, samba was upgraded from v4.4 to v4.6 which prevented authentication to the shares.
* Review [[https://www.samba.org/samba/history/samba-4.5.0.html|Samba 4.6 release notes]] and see that "ntlm auth = no" is now the default.
* Use [[https://www.samba.org/samba/docs/man/manpages-3/smb.conf.5.html|samba config docs]] for troubleshooting
**June 2017 - Adding a CAC smart card:**
* Add the "vboxusers" group to the linux account that normally runs VirtualBox
* A reboot may be required
* Download the VirtualBox Extension Pack
* Open VirtualBox and go to File > Preferences > Extensions
* Install the Extension Pack you just downloaded
* As root: VBoxManage list usbhost
* Follow rest of instructions from work
**October 2016:**
* Running a text-only version of a VM guest does not shut down cleanly
* I thought that changing the GRUB2 default resolution fixed it, but it does not
* See [[centos_7_migration_notes|CentOS 7 Migration Notes]] for details on how to change default screen resolution
* Problem is [[http://forums.whirlpool.net.au/archive/2531732|possibly fixed in CentOS7.3]]
* Other option is to try setting base memory to 1024 MB (512 MB had problem)
**September 2016:**
* Updated host computer to kernel-3.10.0-327.36.1.el7.x86_64 and VirtualBox would not start
* su - root
* /sbin/rcvboxdrv setup
* Took about 10 minutes to run, it reset the DKMS packages and normal startup resumed

yum install wget
Follow instructions to [[http://www.45drives.com/wiki/index.php/Installing_MATE_on_CentOS_7|Install MATE Desktop]]
Note that there might be a problem with installing the "Development Tools" group. If so, follow these instructions:
# yum groupinfo -v "Development Tools"
# yum groups mark install -v "Development Tools"
# yum list updates (note: you will see a bunch of packages to install now)
# yum -y update
Continue with the rest of the MATE desktop installation steps.
Proceed with [[centos_7_migration_notes|CentOS 7 Migration Notes]]
Before migrating users' $HOME, make a test user on CentOS 7 and on CentOS 6. Login to each graphically. See if the hidden files have changed format and use that info when migrating the $HOME directories.
Remove open-vm-* packages as they are not needed on non-VMWare machines:
* [[https://bugzilla.redhat.com/show_bug.cgi?id=1251656|Redhat bug tracker]]
* If open-vm-tools does not want to uninstall, at least remove open-vm-tools-desktop and open-vm-tools-devel.
After everything is configured make a clone and deploy as needed:
* Change the hostname
* Change .muttrc files (for each user) for the new hostname
* Reinitialize MAC address
* When connecting for the first time, may need to left-click network icon and connect to "Auto Ethernet" network and make sure it's set to auto-connect. Then delete other, pre-existing network.
* Reserve DHCP IP address in LAN router
