By default it uses raw .avi which takes a lot of space and will not play on a lot of systems.
It's best to change the codec to something like MP4.

If you get this error when trying to SSHto a device or machine and you never even got a password prompt:
Too many authentication failures
This means that either the remote side is configured for key auth only, OR your client side may be attempting to auth using mulitple keys, and that exceeds the amount of attempted authorizations on the remote ssh server.
If the issue is trying to auth too many times which ssh defaults to sending the keys to, you ca........
If you are using mint, delete the preference that stops snap from installing (as it is required for lxc)

1. Install lxd:
sudo apt install lxd

Debian at this time does not have lxd so you'll need to use snap:

NAT Network, the VMs can communicate but your host cannot access them by default.
NAT VMs have internet but cannot communicate with each other.
Bridged is simple and allows full LAN access as if you had a physical machine plugged in but is often bad for testing, work or corporate environments and is not very portable when it comes to moving your VMs to other locations and networks.
Here is how you can use NAT Ne........
The Linux Mint team has disabled it by setting an apt preference, you can edit or just remove the file:

This seems to happen on most if not all Nvidia cards but the good news is that if you are using any of the Linux drivers and have the nvidia-settings tool installed it is just a simple command.
Solution:
nvidia-settings --assign CurrentMetaMode="nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"
Enter the above command in your terminal and the screentearing will be fixed which is like enabling Tear Free on AMD cards.&........
Install Errors on Version 12:
This error happened on QEMU emulator version 2.11.1 pve-qemu-kvm_2.11.1-5
on Proxmox/Debian but installing on QEMU.12 on Centos 6 did not produce the error.
*Update it is not related to the OS or QEMU version. This happened in Centos 6 too after a second install.
What really causes this even though you successfully install........
The strange thing is that usually the first install or two will work on any new machine but then it suddenly won't. I had this experience on QEMU 2.13 on a different machine. There is something finicky or buggy about the CUCM installer even when choosing the same virtual hardware specs.

initiator = client
target = server
These are the first concepts you should understand which is that in iscsi essentially the "initiator" is the client and the "target" is the server.
iSCSI is derived from the old fashioned SCSI that us oldtimers grew to love. The "i" stands for Internet and the SCSI stands for "Small Computers Systems Interface" (SCSI).

Did you just install the minimal version by accident or want to install the GUI? No need to reinstall just tell yum to do the work for you!
You could actually have both installed and choose one as your preference on demand (although many people prefer GNOME's simplicity).
Step 1.)
Install Gnome and/or KDE.

I've used rsync again for this because I found it very simple, I've only excluded the Cache directory since it's not necessary and could be several GB in size.
rsync -Phaz --exclude=Cache/* user@remotehost.com:/home/user/.mozilla/firefox/profile.default/* /home/user/.mozilla/firefox/ec1n9opl.default/
