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?
It should be. The ARM folks use it all the time (I suppose).
Did you properly define the network device within the guest? MMIO doesn't have automatic detection
like PCI does.
Thanks,
Sasha
