Description of problem:
When cluster policy with pintohost is active. Then when vm which is not pinned to
any host is migrated with 'auto selected host', this vm fails to migrated and
is shuted down.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Create two hosts. in cluster which use policy with only pin to host filter.
2. Create vm which is not pinned to any host and run it.
3. Try to migrate this vm with option 'select host automatically'.
Vm fail to migrate and is shut down.
Vm will migrate.
Happend also when other filters are active, not only pin-to-host.
I'm missing the log parts from the scheduling process. Can you please add them?
Also, what is your cluster policy optimization (servers? desktops?)
There are several options that allow overcommitment, such as ksm, ballooning etc
so we really need you to specify all these settings to evaluate the memory calculations.
Please ignore previous comment.
Are you using one of the existing policies or did you create your own?
I used only pin-to-host internal filter.

What about actual memory availability? ie- optimization, etc?
I didn't use any optiomizations. no page sharing, ksm and ballooning
This problem also appers when I do:
Using RAM filter, overload RAM of host1
create vm and run it on host2. try to migrate this vm to host1,
migration also fails and vm is going down.
When I add to RAM filter also migration filter, then the problem don't appear
tested on is17
