Ok, its all good.

I would go with SeijiSensei suggestion. vBox 6.0 has been released.

How much ram do you have?

free -g

[iamtheeggman2]

also id like to utilize more of my cpu, its currently set to 1 but it said you need hardware stuff installed first, is that easy to install?

12gb ram - i let vobx use 3gb for the guest box

[cruzer001]

There is a fairly heavy learning curve to vBox, but IMO its worth it.

One core will be slow, two core for the guest is far better for a GUI.

[iamtheeggman2]

wiow i tried one mor time and it work! no idea why.

i still need o get more cpu usage though.

[cruzer001]

vBox manager will allow you to up it to 2core, the guest must be shut down first.

Been here yet?

If the host OS is 32-bit, then virtualbox will only use software-based virtualization and it is limited to 4G RAM for the entire guest and all support RAM use like video RAM.
Hardware acceleration will not work without a 64-bit host OS.

IME, virtualbox is the slowest of all the hypervisors. I've never had issues with allocating just 1 vCPU to a VM, unless the VM was running lots and lots of processes. My everyday desktop runs inside a VM with 1 vCPU and 3G of RAM. If you run a heavy desktop or Zimbra server, then a case that 2 vCPUs could be made. I have webservers running in separate VMs with 10+ virtual domains. These all share 1 vCPU and 1G of RAM and less than 5G of storage total.

Still relevant virtualbox tuning article: https://blog.jdpfu.com/2012/09/14/so...-in-virtualbox

BTW, flash is dead.

Yes, vBox can suck up some resources. Gaming on two core can hit 100%, stay at times at 80 to 90%. Ended up giving 4core/4G ram to that VM. And this is not high level gaming, VB is just not designed for this.

Same with ram, 2G minimum (3G can provide a better experience) and storage I usually set to 12G.

For gaming, either VT-g (intel iGPUs) or VGA passthru are really the only options. Without access to a real GPU, then the CPU has to handle all that rendering. I support virtualbox is the best option for gaming in a VM without using passthru or VT-g. I haven't tried SPICE on KVM for gaming. My KVM servers aren't for gaming.
Plus, the guestOS matters greatly. A Linux VM is much, much, lighter than Windows. Windows VMs tend to use 30% of the CPU inside the guest just because. I've never figured out why this is and it doesn't happen all the time, but once it does happen, reasons unknown, the Windows VM will keep sucking more and more CPU.

I have lots of VMs that have less than 1G of RAM allocated. These aren't desktops. Desktop virtualization is a 5% thing for me - 5% are desktops, 95% are servers - no GUI.

In the link above, I do mention switching from virtualbox to KVM some years ago. Can't imagine going back. virt-manager makes using KVM pretty much just like virtualbox, but with much more flexibility.
