Hi everybody,
I have a problem with KVM installed on Fedora 17. Yesterday I installed it and it worked perfectly (I used KVM GUI, made two new VMs, installed F17 and F18 on them and it worked). Today, I turned on my PC and launched KVM GUI but I can't start my VMS, even I can't create a new one.

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/", line 96, in cb_wrapper
   callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/", line 117, in tmpcb
   callback(*args, **kwargs)
  File "/usr/share/virt-manager/virtManager/", line 1090, in startup
  File "/usr/lib64/python2.7/site-packages/", line 554, in create
   if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: unsupported configuration: Domain requires KVM, but it is not available. Check that virtualization is enabled in the host BIOS, and host configuration is setup to load the kvm modules.

Could you help me what's now wrong?

Have you checked that virtualization is enabled in the host BIOS?

The problem was that virtualization was disabled in my bios. It's quite strange because KVM worked after installation.
