It's great to see that a lot of people are starting to consider upgrading to vSphere 5.1 and are upgrading their lab environments. vCloud Networking and Security is one of the jewels in the crown for VMware and it's expanded functionality, including high availability, means it is an even stronger candidate for enterprise firewall replacement in addition to it's use cases with vCloud Director. I had used the previous version in an enterprise firewall replacement project and discussed that in Enterprise Firewall Replacement with vShield Edge and vShield App.
There are a number of considerations when upgrading to vSphere 5.1 covered in my article vSphere 5.1 Generally Available – Important Upgrade Considerations. However a specific issue has come up with some upgrades to vShield Manager 5.1 that you need to be aware of. This article will try and help address this particular issue.
A number of people have been reporting problems with vShield Manager after the upgrade to 5.1 with symptoms of a kernel panic after modifying the guest to 2 vCPU's and 8GB RAM as recommended. The reason the kernel panic is occurring in most cases is that the vShield Manager is now 64bit and will require you to change the Guest OS type in vCenter from Other 32bit to Other 64bit. You will also have to change the vSCSI controller from BusLogic Parallel to LSI Logic Parallel. Failure to do this will render your vShield Manager VM inoperative. If you make these simple changes when you change the vCPU and RAM you should have no problems. Remember with vShield Manager 5.1 there are 3 different configuration types and it's important to match the virtual hardware configuration to the correct configuration type. I would expect a KB article to be posted by VMware very shortly on this topic and when I know what the KB number is I will link through to it.
Based on the above and another issue that is discussed in KB 2035939 re vShield Edge Disk Full Error. I would recommend that you upgrade to vShield Manager 5.1.1 as soon as practicable.
