Knowing and hardware configuration/information on Qubes (Specifically available CPU cores and RAM)
Sphere
Along the way however, I was able to see through Dom0 Task Manager that the amount of Memory/RAM available is only 3.8 GiB but my laptop has a total of 12 GB worth of RAM D:
Is there a way for my Qubes to recognize and use the rest of the ram?
Also, is there a way for me to see just how many CPU cores are recognized by the Qubes OS?

available to Qubes. The figure you see in task manager is merely the
limit for dom0, not the whole system.

Thank you very much! I couldn't find that anywhere by googling.
Though, I have a concern with regards to the info I saw
When I ran the command, it says it correctly sees total memory as 12153 however, I was really surprised that only roughly 2 GB were available and the only things I have up were dom0, sys-net, sys-usb, sys-whonix, and vault
After killing vault and sys-whonix, I was able to make it have 5 GB free
Are VMs really that overkill? @_@
Is there a way to optimize this? I noticed that it seems I can't reduce the max memory for sys-net and sys-usb. While I can reduce it for sys-firewall, I'm concerned that reducing it may lower it's capability to withstand network-based attacks.
Is there any way I could optimize this? If possible I'm really looking to at least be able to have 6 GB to 8 GB free to use on the Windows 7 HVM that I am going to make.

less that has to be loaded from slow disk. However, just because it's
"using" the RAM does not mean it is unavailable for other purposes. That's
where memory balancing comes in. If you start some more VMs, Qubes/Xen
will reduce the amount of memory available to the others (down to the per
VM minimum if needed) in order that they all fit.

their maximum. Wouldn't recommend making them any lower.

errors when starting a VM.
