Once a VM starts, its OS automatically checks whether the driver version is consistent with that offered by Space Console. If the VM's driver version is lower than that offered by Space Console, you can upgrade the driver by performing one of the following tasks:
Auto driver upgrade—Enable automatic driver upgrade for the VM. For more information about this feature, see "Edit a VM. "
Manual upgrade—If you do not enable automatic driver upgrade for the VM, do the following to manually upgrade the driver:
From the left navigation pane, select Data Center >Virtualization > Cluster name > Host name > VM name.
Click More, and click Upgrade Driver.
