vSMP Fundamentals
Daemon Behr has written a nice and succinct article on when and how to use more than one virtual CPU in a Virtual Machine.
A few of the highlights:
- Be very selective with vSMP only use it when applications can take advantage
- Don’t assign a VM the same amount of vCPUs as you have pCPUs
- Remember to change HALs for migrated physical machines if necessary
I know most of this is taught during the training courses, but you’d be surprised how many installs I have been to that have ignored them.
Always useful to keep in mind.
