I upgraded XenServer to a 6.2 pool.  I have one server joining the pool that has X5650 processors and the rest of the pool is on X5550.  What is the mask that I should apply to the server?  The server joined the pool on upgrade but will not allow VM's migrated out of it because the host doesn't have the same CPU features.

You should set the masking before joining the pool. So first thing is remove it from the pool.

Next if you want a successful masking then you need to ensure the following conditions are met:

1. The CPU on the server you want to join the pool should be from the same vendor as the CPU on the server in the pool. So if the CPU is Intel then you should have it Intel. It doesn't have to be from the same model or family.

2. If the CPU is Intel then it must support Intel FlexMigration. If it is AMD then it must support AMD Enhanced Migration.

3. The features of the CPU of the server in the existing pool must be a sub-set of the features of the CPU of the server you want to join to the pool.

4.  The server you want to join the pool should be of the same XenServer version and at the same level of hotfixes as the servers already existing in the pool.

5. This only works with XenServer Advanced edition or higher.

If all the conditions above are met then next do the following for masking:
1. On the Pool Master run the following CLI command
xe host-get-cpu-features

Open in new window

.

2. Copy the features you get.

3. On the new server, run the following CLI command pasting the pool master features in the features parameter
xe host-set-cpu-features features=<pool_master's_cpu_ features>

Open in new window

4. Restart the new server.
5. Join the new server to the pool.
