Arbadacarba Posted February 14, 2020 Share Posted February 14, 2020 I have a Gaming VM (Win10) set up using my NVMe drive in passthrough and am really happy with it. The system I built is more economical than performance but having gamed of a laptop for the past 10 years I find it more than I need. I'm running into one problem though, and it's more of an OCD issue than a real problem. I originally set the Gaming VM to use 16GB or Ram for Startup and Max - and as I said that is working fine. But I noticed that my memory reports as 62% used in the Unraid dashboard... Even when I'm not currently using the VM (But it is running). I tried changing the numbers to 8GB - 16GB (I'd actually set it to 24GM if this worked) but it changed the max memory to 8GB when I started the VM. I assume this is because Memballoon is set to none. I tried turning memballoon on but don't know what to confugure the PCI address as. I did find one that worked... but even with it running my dashboard sits at 62% Memory Usage. Am I just not understanding what it should look like? Should I avoid this in general to keep the performance of the VM optimal? Here's my current XML for the VM: Arbadacarba Win10XML.txt Quote Link to comment
testdasi Posted February 14, 2020 Share Posted February 14, 2020 Are you looking at overall usage i.e. including ram cache? Linux actively uses RAM to cache write and reports it as not-free but once required, it can easily be freed up automatically. In fact, 62% usage means 38% wasted RAM. You want as close 100% as possible. Quote Link to comment
Arbadacarba Posted February 15, 2020 Author Share Posted February 15, 2020 I'm not certain... I'm going by the Dashboard. Here it is without the VM running: And here it is with the VM running: Quote Link to comment
PeteAsking Posted February 15, 2020 Share Posted February 15, 2020 If you have more than one vm you can save memory by enabling the kvm Kernel Samepage Merging feature eg: 2 windows vms etc Quote Link to comment
Arbadacarba Posted February 15, 2020 Author Share Posted February 15, 2020 Though I do have multiple VMS only one runs all the time. Quote Link to comment
