TL;DR:

 

Use proper CPU pinning to avoid issues with VMs.

 

For example:

 

if you have 4 cores + HT.

 

0 + 4

1 + 5

2 + 6

3 + 7

 

And have an *even* number assigned.

 

*** RESOLVED **

 

Looks like I have an issue with starting up VMs... The VM starts to boot, then two out of the three assigned cores are pinned at 100% and a few minutes later the VM crashes...

 

Not much from the logs either...

 

Host OS:

unRAID 6.3.5

 

Host HW:

Intel Xeon E3-1270v2

32GB DDR3 ECC RAM

Fujitsu D2607-8i (Flashed to 9211-8i)

8x4TB Hitachi Ultrastars

2 x 1TB Crucial M500 SSDs (VMs run on the SSDs)

 

VM - Windows 10

what guide did you follow creating the vm?

Confirmed, the issue is with Hyper-V Features. Once disabled, system boots no problem.

 

No guide. I just went in, selected windows 10 template, populated there rest and installed.

There are optimizations you may be missing out on for better vm performance.

Could you give me a particular example?

 

 

 

The first guide is a very basic setup. The second guide is more advanced. My VM provisioning process covered the tutorials. Thank you for sharing regardless.

Most people who just go commando on vm setup miss little things, which resultsin degraded performance.

No doubt, I genuinely appreciate you taking the time to try to helping out. Pardon me if I sounded arrogant. I have worked with many virtualization platforms. So the basic troubleshooting was done.
