Whenever I put a host in maintenance mode via scvmm, it starts migrating all VMs to other host, but once it gets to the last 3-4 VMs, the host that is going into maintenance mode crashes and reboots before being fully evacuated.
I've learned to manually migrate important VMs before putting into maintenance mode because it does this every time. If there are only a few VMs on the host when I turn on maintenance mode, it evacuates just fine. I'm not sure what the magic number is that makes it crash. I was installing updates today, which was why I was going into maintenance mode, but it rebooted before I could even start on that.
What should I look for to find the cause of the reboots?
Hyper-V Server 2012 R2
SCVMM 2016
2-node cluster
Dell Compellent Fiber Channel shared storage
~35 running VMs
