I recently upgrade from vCenter 5.0 to 5.0 U1, and ran into this issue.
I saw the following problems.
I see upgrade vCenter Agents on cluster hosts in recent tasks.
And after a services restart, It would disconnect all VMware Hosts.
The following KB Addresses this.

I thought it would be a good read for those of you that haven’t pulled the trigger for a U1 update yet.

Symptoms
After upgrading to vCenter Server 5.0 Update 1, you experience these symptoms:
* vCenter Server tries to upgrade the vpxa agent and all hosts are marked as disconnected
* In vCenter Server, you see the Upgrade vCenter Agents on cluster hosts task in progress, but the task never completes
* This issue may occur if the upgrade of vpxa agents was set to manual in a previous upgrade of vCenter Server
* In the vpxd.log file, you see entries similar to:vpxd-14370.log:2012-03-21T08:43:19.447Z [fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”][03512 info ‘Default’ opID=SWI-b1839753] [VpxdHostUpgrader] Preinstalled bundle found: not installing

Cause
This issue occurs if the autoUpgradeAgents option in vCenter Server advanced settings is set to false and vCenter Server incorrectly tries to upgrade the vpxa agent a second time on the ESX/ESXi hosts
Resolution
To workaround this issue, change the autoUpgradeAgents option to true.
To change the autoUpgradeAgents option to true:1. Click Administration > vCenter Server Setting > Advanced Settings.
2. Look for the AgentUpgrade.autoUpgradeAgents option and change this setting from false to true.
3. Restart the VMware VirtualCenter Server service.
4. Manually reconnect all ESX hosts.The Upgrade vCenter Agents on cluster hosts task should now complete.

I thought it was a good to know KB.
