Hi All
We have two dell hosts within a cluster I am having massive issues with.
Host01:
OS - Server 2016 DC
Model - Dell PowerEdge R730xd
CPU - Intel(R) Xeon(R) CPU E5-2650 v3 - Intel64 Family 6 Model 63 Stepping 2
Host02:
OS - Server 2016 DC
Model - Dell PowerEdge R740xd
CPU - Intel(R) Xeon(R) Gold 5115 - Intel64 Family 6 Model 85 Stepping 4
Live migrating from host01 > host02 - flawless.
Migrating from host02 > host01 flags errors all over the place for every VM:
"Live migration of 'Virtual Machine MOD01' failed.
Virtual machine migration operation for 'MOD01' failed at migration destination 'HOST01'. (Virtual machine ID)
The virtual machine 'MOD01' is using processor-specific features not supported on physical computer 'HOST01'. To allow for migration of this virtual machine to physical computers with different processors, modify the virtual machine settings to limit the processor
features used by the virtual machine. (Virtual machine ID)"
The compatibility checkbox is very enabled - quick migration (from a started state) won't start the machine at all on host01. Only way I can migrate within this cluster is with the servers offline which isn't especially cluster like and will cause issues
during the next CAU update window (yes - this has previously successfully performed CAU just last month!)
I've googled to the extreme and all I can find is "enable the checkbox" which is already enabled. The VM's are in a mixture of Configuration version 5.0 and version 8.0. Previously I was able to migrate majority of servers with only one or two having the error (which were just test machines so shutting them down wasn't a major issue) but now - its every machine on the newer host.
Is anyone able to provide any direction for this one as I am at a complete loss here.
Thanks.
