Needing a moment of headspace I decided to spin up the latest Windows 8 Release Candidate on my KVM platform at home…
I pulled the image from: http://windows.microsoft.com/en-US/windows-8/release-preview
Lets kick off the install:
I selected Windows 7 as Windows 8 is not yet an option.
I selected kvm and an x64 platform (the RC is a 32-bit) but it shouldn’t matter.
The first attempt failed rather miserably with a typical Microsoft style error of ‘limited’ usefulness:
Not exactly useful – but the error is actually trying to tell me I am using an unsupported CPU. Ok, so lets take a quick look at how the CPU is configured on KVM by default:
Notice how every single CPU feature is turned off by default …. Well, Windows 8 supposedly needs at least the following:
So, quick fix – either set these manually or “Copy from Host”:
This applies the required bits.
Shut down the KVM and start it again:
So, short and sweet — setting CPU defaults on a KVM is a bloody useful thing to do!
