So i am using Ubuntu 19.10 and recently installed virtualbox on my pc but there is a problem to use virtualbox.

As you can see in the above screenshot, there are some invalid settings. (System Acceleration page: The hardware virtualization is enabled in the Acceleration section of the System page although it is not supported by the host system. It should be disabled in order to start the virtual system).

So now i am unable to install any 64 bit version of any operating system in my ubuntu virtualbox.

I had exactly the same problem with a Gigabyte motherboard and AMD Ryzen processor.

Hyper-V was already disabled in Windows (the only solution I could find).

Turned out, I had to enable hardware virtualization in the bios (set 'SVM Mode' to 'Enabled'

TL;DR

Despite suspicions and red herrings, SVM was indeed disabled in my BIOS. I post this so others may go directly to that.

First red herring:

svm is present in flags. I immediately started looking elsewhere for the problem, as I thought that if it shows up here, then it means SVM is enabled. This is not true.

I suspected docker has something to do with this. I read that somewhere. Second red herring. But stopping dockerd didn't fix the problem. Even rebooting with docker disabled in systemd did nothing. No wonder.

I'm certain this was working a few weeks ago on this very machine. Third red herring. If it worked before, then it must work again.

I suspect now that a bios upgrade I did a week or so ago must have set the SVM setting back to disabled. This is as close as I can come to root cause at this point.
