- cpuid_7_0_ebx_features

- kvm_features
- svm_features
This will ensure the "enforce" flag works as it should: it won't allow
QEMU to be started unless every flag that was requested by the user or
defined in the CPU model is supported by the host.
This patch may cause existing configurations where "enforce" wasn't

KVM_CAP_PV_MMU capability reporting was removed from the kernel since
v2.6.33 (see commit
a68a6a7282373), and was completely removed from the
kernel since v3.3 (see commit
fb92045843). It doesn't make sense to keep
it enabled by default, as it would cause unnecessary hassle when using
the "enforce" flag.
This disables kvm_mmu on all machine-types. With this fix, the possible

------------+----------+----------------------------------------------------
src kernel | dst kern.| Result
------------+----------+----------------------------------------------------
>= 2.6.33 | any | kvm_mmu was already disabled and will stay disabled
<= 2.6.32 | >= 3.3 | correct live migration is impossible
<= 2.6.32 | <= 3.2 | kvm_mmu will be disabled on next guest reboot *
------------+----------+----------------------------------------------------
* If they are running kernel <= 2.6.32 and want kvm_mmu to be kept

A blank CD or DVD is visible as a zero-sized disks. Probing such
disks will lead to an EIO and a failure to start the VM. Treating
