Here are the in my opinion most interesting SharePoint 2007 resources in May 2009.

With every link comes a short description of the content available.

This month is about SharePoint 2007 in general and WCMS as well as virtualization.

SharePoint 2007 WCMS

• SharePoint Master Page Content Place Holders
  The UK SharePoint Team has released a table which “provides a list of the ContentPlaceHolder Ids and corresponding UI element for the default.master Master Page”.

• The April cumulative update for WSS V3 and MOSS 2007 has been released yesterday
• Red is Green, Up is Down and the Unsupported suddenly becomes Supported!
• MOSS 2007 Blob caching and it's limitations
• MOSS 2007 SP2 - a must have for everyone who uses Variations on his site
• Technet article on how to troubleshoot Content Deployment has been released
  Stefan Gossner has written some interesting and important articles in May 2009. You should definitely check them out! :)

Virtualization (Hyper-V)

• New in Hyper-V Windows Server 2008 R2 Part 1 – Dedicated Networks
  John Howard always describes important things like networking with Hyper-V with a lot of pictures.
  
  
• Hyper-V and in-place upgrade to Windows Server 2008 R2 Release Candidate
  Don’t disable the Hyper-V role even if you read a notice while upgrading Windows Server 2008.
  
  
• Hyper-V R2 Import/Export – Part 1 – The Case for New Import/Export Functionality
• Hyper-V R2 Import/Export – Part 2 - The New Import/Export APIs
• Hyper-V R2 Import/Export – Part 3 – The UI
• Hyper-V R2 Import/Export – Part 4 – Export code sample
• Hyper-V R2 Import/Export – Part 5 – Import code sample
  Not satisfied with import and export in Hyper-V v1? Here are the new features like “Copy on Import” (missed that one a lot in v1).

Hope you like them.
