I could never remember all that and I would always have to refer to documentation to know how to write out the full commands.
On the other hand, I can download an ISO for almost any popular Linux distro and easily install it without reading a single word of documentation, even if I've never used that distro before.
Yes, these commands have way too many options for anyone to remember. The commands are best wrapped up in a script. An ISO install is usually a manual process that can take time, but it is definitely easier.
waiy what? you don't need to learn complicated commands.
Just interactively setup a virtual machine and at the screen that provide you the choice of your disk size, you just select the option to use an existing disk and select it.
It is e.x.a.c.t.l.y the same. Instead of selecting an image for the virtual dvd drive, you select an image for the hard drive, or an image for an usb drive. It is as fast and as simple either way with the advantage of not having to go through the install process if you just start fe the hard drive image. The downside possibly being download size compared to say, downloading a netboot iso that will install the latest packages from the very start.
Sounds to me like you're one who is doing the VM right, as effectively as anybody.
I wonder what people think about this,
When I was first doing VMs, I would have the image in a file and it had to be stored somewhere.
All I would have in the file, would be an OS and maybe a couple apps installed.
Really only takes up a few GB of drive space as long as I don't try to store any massive or valuable data within the image.
I wouldn't want that kind of data in my images anyway.
And I had plenty of drive space so I didn't need any compression or space-saving measures to be applied for storing images.
In this case the working image takes up the exact same space on some drive either way.
Might as well let the image stay installed on its own partition so I could boot to it the bare metal way when I wanted to, or alternatively use it as a VM when re-booted to a powerful enough host OS which has been previously installed to a different partition.
Now in the terabyte world I've got more spare drive space than ever, and with GPT drive layout I can have as many partitions as I want.
