Regarding devices which devices qemu-kvm supports, just take a look at |
| 2 |
following commands: |
| 3 |
Available net devices: |
| 4 |
qemu-system-x86_64 -net nic,model=? |
| 5 |
Available cpu's: |
| 6 |
qemu-system-x86_64 -cpu ? |
| 7 |
Available machines (if needed) |
| 8 |
qemu-system-x86_64 -machine ? |
| 9 |
General list of available devices: |
| 10 |
qemu-system-x86_64 -device ? |
| 11 |
|
| 12 |
Depending on your arch it might differ.. |

Regarding virito devices: |
| 15 |
I highly recommend using those drivers. For my gentoo guests i always use |
| 16 |
virtio drivers for network devices (with vhost=on) and harddisks. (on |
| 17 |
windows guests only virito-net drivers) The performance gain is incredible. |
| 18 |
However, especially for the virtio harddisk driver, make sure you change |
| 19 |
fstab entries, because harddisk names change from sda to vda (or just |
| 20 |
use them from the beginning. |
| 21 |
|
| 22 |
If you going to try out desktop vm's too i also recommend qxl with spice. |
| 23 |
It's really fast and it also supports copy/paste (however you need an |
| 24 |
service for copy/paste on linux "app-emulation/spice-vdagent") and window |
| 25 |
resizing. Those features also work on windows. |
| 26 |
|
| 27 |
Regarding libvirt my experience is actually very low since i setup my vms |
| 28 |
with an custom init script. You can take a look on it here: |
| 29 |

| 30 |
|
| 31 |
I can also provide a basic kernel .config for the latest stable kernel on x64 |
| 32 |
and x86 if you are interrested. |
