For video, I tend to use Cirrus. (I'll get the serial console stuff |
| 18 |
figured out eventually; I know how that works in the guest, but haven't |
| 19 |
prodded it in the host.) I didn't see a guest-side driver for vmvga, and |
| 20 |
I have no idea what qxl is. (I didn't hit search engines for it, I was |
| 21 |
merely searching around via menuconfig's / search.) |

Virtio drivers are awesome, of course. |

What I'm really looking for, though, is a list of all the devices the |
| 26 |
qemu/kvm host can emulate, and the most-specific guest driver. I.e. If I |
| 27 |
wanted to make a generic kernel configuration that contained the optimum |
| 28 |
drivers for all possible qemu/kvm configurations, what would be the |
| 29 |
minimum feature set? |
| 30 |
|
| 31 |
While I'm on the subject...menuconfig's search functionality indicated |
| 32 |
there was a vmguest-targeted CPU accounting in the kernel, but I |
| 33 |
couldn't get the HAVE_VIRTUAL_CPU_ACCOUNTING dependency flag set, and |
| 34 |
couldn't figure out what set it. Any ideas there? |
