Hi, I was just wondering if there are any particular issues or configuration settings I should be aware of when running my cluster oh VMs rather than bare metal. Currently running ES 6.4 in ESXi 6.5. A few people have suggested to me that I should disable VMotion and consider pinning instances to certain CPU cores. Is this correct or a load of rubbish?

I'd be interested to hear people's thoughts and experiences.

Thanks  
Jim
