    The description of the problem states that the 1st part of the output should be (VMPLACEDBEGIN/VMPLACEDEND) and second should be (VMNOPLACEDBEGIN/VMNOPLACEDEND).However in all the examples we can only see (VMNOPLACEDBEGIN/VMNOPLACEDEND) and not (VMPLACEDBEGIN/VMPLACEDEND).e.g-In the first example I see that vm1 and vm2 were placed in host,but output does not show any (VMPLACEDBEGIN/VMPLACEDEND).It just shows that vm3 was not placed.Can someone explain this?

      For the outout related question my guess is as below,
      there are two host
      host1,5,100
      host2,2,50

      and three vms
      vm1,1,50
      vm2,4,20
      vm3,1,80
      BUT flow of starting vm are vm1,vm3,vm2
      So, first vm1 will take host1 (having 5 cpu and 100 memory) so remaning resources are
      host1,4,50
      host2,2,50

      NOW, vm3 is ON but there is no host with 1 CPU and 80 memory so it will not fit
      Then vm2 is ON and there is host1 with 4 cpu and 50 memory so it will ho with host1,
      This way vm1 and vm2 will schedule but vm3 will not

        For three VMs:
        vm1,1,50
        vm2,4,20
        vm3,1,80
        and 2 hosts:
        host1,5,100
        host2,2,50


        I think all three can be placed, as shown below:-
        1. vm1 ON : place it on host2
          remaining resources are:-
          host1,5,100
          host2,1,0
        2. vm3 ON : place it on host 1
          remaining resources are:-
          host1,4,20
          host2,1,0
        3. vm2 ON : place it on host 1
          remaining resources are:-
          host1,0,0
          host2,1,0

        Isn't this right? What am I missing?
        I mean is there a rule that one host can only run one VM at a time?

          You are correct, however for Problem 1, VMotion is set to off. So Each VM will be placed into the first Host that can fit it. VM1 will go on host 1, VM 3 won't be able to find anywhere to fit so it won't be placed, then VM 2 will be placed on host 2. For the other 2 scenarios, VMotion is turned on, so the cluster should load balance and all VMs should be placed.

          Well this is not clear from the problem statement: "The first part of the file (VMPLACEDBEGIN/VMPLACEDEND) will be the name of the VM and the host it was placed on. The second part of the file (VMNOPLACEDBEGIN/VMNOPLACEDEND) will be the names of the VM's that you could not place."

          There is a mention of 2 parts of the output file, while all the samples seem to mention only the second part.

          The wording got me very confused.
