Description Wayne Berthiaume 2009-07-27 13:14:26 UTC 
Description of problem:
kvm, kmod-kvm, and ksm modules will install and load eventhough the server does not contain the supporting hardware to use them. 
Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Install the modules
2. Try to create a VM
3. virt-install -n RHEL_Guest --os-type=linux

  
Actual results:
ERROR    Host does not support any virtualization options


Expected results:
Begin installation process

Process needs vmx feature flag in order to support VT.
Comment 1 Andrius Benokraitis 2009-07-27 13:49:01 UTC 
Wayne, I'm assuming this is a testcase in order to dummy-proof the install?
Comment 2 Wayne Berthiaume 2009-07-27 14:52:02 UTC 
Yeah... I was the dummy. =%^) For now a relase note should be fine and we can hit the dummy proofing on the next pass.
Comment 4 Dor Laor 2009-08-03 08:56:15 UTC 
The kvm package is 100% userspace and can work without VT (-no-kvm flag), so it should be able to be installed.

What's left is to add kvm pre install check for the cpu flags.
KSM is dependent on kvm.
Comment 5 Dor Laor 2009-10-29 22:09:18 UTC 
We can always run kvm with -no-kvm so there is no need for VT.
So we do want to allow these packages to be installed.
