Hi Peter,

First, thank you very much for writing lkvm, it's awesome, and very
easy to set up.

If sending an e-mail to you is not the right way to report lkvm
issues, please tell me how I should do it.

Sure, you can report problems to me and I'll do my best to
try to get them sorted out.

I'm using afdf92030c7c43b0f9b32b7edbe07ac3b13780f1 from
git://github.com/penberg/linux-kvm.git and Linux kernel 3.2.51:

config-3.2.51 (42 KB)
https://mega.co.nz/#!hgxB1TDJ!SdbX-jp_yr8E6EUJl7t7Tzrh1p4qKxkTHieoss8yu_Y
bzImage-3.2.51 (2.0 MB)
https://mega.co.nz/#!5lBVmDZL!WpPRWA7ZflevBIPPNGNM_FkkY-ErBNQMoEbw0XePi5I

Config:

$ grep -E 'VIRTIO|MMIO' .config
CONFIG_NET_9P_VIRTIO=y
CONFIG_VIRTIO_BLK=y
CONFIG_VIRTIO_NET=y
CONFIG_VIRTIO_CONSOLE=y
CONFIG_HW_RANDOM_VIRTIO=y
CONFIG_VIRTIO=y
CONFIG_VIRTIO_RING=y
CONFIG_VIRTIO_PCI=y
CONFIG_VIRTIO_BALLOON=y
CONFIG_VIRTIO_MMIO=y
CONFIG_HAVE_MMIOTRACE_SUPPORT=y

I'm running `lkvm run --network mode=user,trans=mmio', and it fails to
create the eth0 device (`cat /proc/net/dev' doesn't show the device).
With `lkvm run --network mode=user' everything just works.

I have also tried kernels 3.0.99, 3.4.65 an 3.10.15, but they seem to
fail the same way.

Am I using it correctly?

Asias, Sasha, is mmio transport supported by virtio networking?
