VM failed to migrate

[katepalli]

I was asked one Question in my Interview last week where i was unable to answer it, kindly can any one suggest the correct answer... here is the question:

I turned on Maintenance mode in an ESX host, all the VM’s has been migrated to another host, but only one VM failed to migrate? What are the possible reasons?

[sparrowangelste]

itss probably NOT on sahred storage.

or the nic port its connected to isnt avaialble on a different host.

it could also be in in invalid state

[prabuvmware]

It can be due to locked file in ESX as well.

Can you try and vmotion the virtual machine manually? this should give you some feedback as to what the problem is.

Hi,

1. This issue is due to VM is not responding or the VMware tools with in the guest OS are not responding.

I have noticed such issues with VMware ESX 3.5 version,

2. May be the VM is kept in the non shared LUN

3. May be FT is enabled to the VM

Regards,

VNB

Interviewer looking for the obvious one which is, mounted cdrom.

p/s: and that's why I purposely deleted virtual cdrom during my vcap-dca labs
