I get:

It compiles fine without '--virtio' appeneded, but in order to run this Hardened Gentoo VM with spice, I need to configure it with virtio parameters, so this is a VM image we are talking about, and the compiling is being done in the VM and not on my baremetal system. My Fedora VM image works fine with spice, as it already has virtio support prebuilt into the kernel. The Gentoo VM works fine when not run in spice, and I am obviously able to run it and compile the kernel to execute these commands.
Here is what I am compiling with:
| Code: | │ │ <M> PCI driver for virtio devices │ │
│ │ [*] Support for legacy virtio draft 0.9.X and older devices │ │
│ │ <M> Virtio balloon driver │ │
│ │ < > Virtio input driver │ │
│ │ < > Platform bus driver for memory mapped virtio devices |
| Code: | │ │ <M> Virtio block driver │ │
|
| Code: | | │ │ <M> virtio-scsi support │ │ |
If you need any other info, please ask! Also, I can run this VM in snapshot or persistent mode, so if it messes up, I can easily revert, so don't be shy! 
*** SOLVED ***
The trick was that I didn't need to use the '--virtio' parameter, but I needed to turn off 'automatic setup' for Grsecurity in the kernel so that I could enable paravirtualisation and some other features and turn the aforementioned modules into built-ins.
All fixed and running now. Thanks guys, couldn't have done it without you!  ...  |
