Hey guys, currently im running 2 virtual machines on an unraid setup. the server configuration is below followed by the VM config's

 

Server

Intel 3970x

Gigabyte GA-x79-UP4

32GB 1333mhz ram

2x256gb samsung ssd's (Cache)

2x120gb samsung ssd's (Array)

1x320gb seagate hdd (Array)

1x2tb seagate hdd (Parity)

 

VM #1

Windows 10

16gb ram

3 physical 3 virtual cores (cores 6-11)

GTX 980

OVMF Bios

60gb cache drive allocated

 

VM #2

Windows 10

8gb ram

3 physical 3 virtual cores (cores 0-5)

AMD Radeon 6950

Seagate Bios

60gb cache drive allocated

 

In the unraid GUI it shows as 4.0 GHZ which is the current configuration for my cpu. Currently i have it set in my go script to set all of the CPU's to performance mode. But my VM's are defaulting to 3.5 Ghz which i find to be odd. My VM's are also affected by this while gaming. with a high cpu usage. it doesnt matter how good your video cards are if the CPU can't keep up. and it should be able to keep up with 2 VM's just fine. The only other thing running on the machine is a teamspeak server inside a docker app. any insight on this would be greatly appreciated.

 

CPU 0 seems to spike on the seagate VM causing it to have issues with the game in question (counter strike global offensive)

First thing I noticed is poor cpu resource splits. You should split your cpu cores differently.

 

You're sharing all the same physical core between 2 VMs. Core 0 is paired with core 6, so one of those is a physical core and the other is the hyperthreaded core for the same physical core.

 

Unraid dashboard displays cpu cores paired properly so pay attention to that.

Perfect that is definitely something i was un aware of I will try splitting the resources correctly now.

 

Perhaps you also know why my VM's are showing as 3.5Ghz when its overclocked to 4.0Ghz? and both of them are using the host passthrough method.

definitely seeing a steadier cpu utilization on both VM's now. Instead of having a single core spiking its more evenly distributed, and doesn't seem to be affecting the game nearly as much.
