XenServer 6.5 and Windows 10 Memory Management
-
So in the below picture I clearly have 8GB of RAM allocated to this VM. But in the memory portion on the left 1/4 GB are used.
Did Microsoft just update this to show the allocation to the OS (4GB cap) or what? Help me understand this because I'm curious as to what is going on here.

What version of Windows 10 are you running?
-
Windows 10 Pro
-
-
64
-
Dynamic Memory I'm betting unless it's 32bit
-
The system definitely believes that you have 4GB of RAM there. Do you have 4GB RAM and 4GB swap?
-
Did they release a 32bit Windows 10?

Yep. Mostly just for inplace upgrades though. Otherwise it wouldn't work.

Hrm...
One second, I just looked at the memory management tab in Xen Center and it list only 4GB...
Gonna do some testing.
-
Just "added" 4 GB more, signing in now
-
Hrm..
Well now it does say I have 8GB to use, but my Committed now says 1.4/16GB...
WTH!

Windows is Autosizing the Swap File to be RAM x2... You could manually set that in 8.1 -- I haven't trired it in Windows 10 yet.

@dafyre OK but... 8GB Swap
-
Maybe if I half it....

I've always run no bigger than 4GB for a desktop OS... Depending on your uses, probably 2GB would be enough... and just set the min & max to be the same.

That's a huge page file. Even in the Windows NT 4 days the recommended was "real memory size + 11MB". Today swap of half memory is normally more than enough.
-
From Microsoft: "If you receive warnings that your virtual memory is low, you'll need to increase the minimum size of your paging file. Windows sets the initial minimum size of the paging file equal to the amount of random access memory (RAM) installed on your computer, and the maximum size equal to three times the amount of RAM installed on your computer. If you see warnings at these recommended levels, then increase the minimum and maximum sizes."
It would've made sense if the SWAP was at 3 times, but it was only doubled.... WTF microsoft.

The page file will autosize itself... If it doesn't need it, it won't take all of it... but if it does need 3x your ram, your computer will be slower than molasses flowing up hill in the dead of winter.

Well I half'd it, set the minimum to 1GB and the Max to 4Gb and now have a Committed of 1.4/9.0GB...
So yeah this VM can't do math... or something else is scaling it..
