but it suggests me to check if my system supports virtualization and by running the following command:
Code:
egrep -c '(vmx|svm)' /proc/cpuinfo
I get as result "0"
That being said, I understand that I must have greater than "0" to be able to use qemu and kvm on my Debian 10 operating system
so, stop and switch to the idea of installing virtualbox on my system, the installation finished without any problem. Now I can virtualize other operating systems.
Later, reading I find out that virtualbox is based on qemu/kvm. Is this correct?
I don't understand why I can't install "qemu and kvm" on my Debian and if I can make virtualbox work
VirtualBox® is an extremely well-supported (by Oracle, no less ...) tool that "runs on everything" and is pretty much designed to "run anything." It is interactive and easy to use. "Just the thing" if you want to "run a guest operating system in a window on your desktop." Just grab it (for free!) and go. It is not a "hobbled horse."
IMHO, the qemu and kvm packages, per contra, are things that you are likely to be appropriate when you want to set up, shall we say, "production environments." They do require hardware support. (Which, as @michaelk pointed out, might be a machine setting that you need to turn on.) They also require a little more hand-holding. But they also should give better overall performance, if that actually matters. (And, these packages tacitly assume that it does.)
My point is simply that the designer-intended use case between the two alternatives is, IMHO, "decidedly different."
