I didn't change vm type. I would set the vm, let it run, do a shutdown, and then when
I went to edit to look at configuration is when it changed. I will test using desktop VM
type and if I do the same things and it stays with what I expected, I will use desktop vm
type and not mess with HP vm type. One thing I did forget to mention is that the vm was
created from a template that was of HP vm type.
Newly created VM (like you create from template), with all the
settings allowing auto pinning (basically, there is default host to
run on) that are set as (even the template without changing the VM
type) High Performance VMs it would set the auto pinning policy to
existing as well.
On creation please look on the Host tab, at the bottom of it, select
the Don't Change option.
Another note is that from 4.4.7 it will become irrelevant and the
existing, including the auto-set of the policy won't happen.
If the information above doesn't help you, then if you can, please add
the engine log.

edit tab to look at what I changed and it is now back to the defaults and my edits are
gone. Is this now the intended result. I was using the same settings in 4.3 and never
exhibited this behavior. What I have observed so for is that I disabled Headless, disabled
cpu pinning, and changed numa config. When I shutdown the vm, they revert to default of
Headless enabled, cpu pinning is set and the numa config changed. This is not what I
expect to happen. Has anyone else noticed this behavior?

you change the type, it will change the policy, but if the VM is already configured as
High Performance and you didn't change it, it will leave it as is.
