Hi all, I have some networking problem. Networking inside UML is always worked, but today it suddenly stopped to work. The command line is the same I've always used: linux ubd0=rootfs.debian.etch ubd1=swapfs.debian eth0=tuntap,,,192.168.1.100 mem=512M During the boot of the virtual machine I get these messages: Configuring network interfaces...SIOCSIFADDR: No such device eth0: ERROR while getting interface flags: No such device SIOCSIFNETMASK: No such device SIOCSIFBRDADDR: No such device eth0: ERROR while getting interface flags: No such device eth0: ERROR while getting interface flags: No such device Failed to bring up eth0. What does it happen? Thank you, Flavio |

Hi Flavio, No worries. You help me get setup, so I'm hoping to help you fix this :) What user are you running UML as? If it's not root, can you try setting it to 0777 and if that doesn't work just change the permissions back. Any errors on the UML boot command (if you can paste a full log right up until the eth0 error, even if I cannot help it might help others diagnose your problem)? Can you try dropping the eth0= at the command line then running a uml_mconsole then adding the config here and seeing if there is any error if all else fails? If everything else fails after that, perhaps you can try using tunctl (this is the method I have used for years without issues) to create a device (like tap0) then attaching it to UML plainly via eth0=tuntap,tap0 This reason I prefer the 'creating a device method' is because you can use tools like vnstat and bwm-ng to monitor live bandwidth.

Haha! Thats exactly the reason, why I subscribed to this list. Got the same error when I try to start some of my 12 UML instances, while others work perfectly. The error happens always with the same UMLs. Permissions are right on /dev/net/tun. Running Debian lenny with 2.6.18-skas3 from etch here. Guests run anything from 2.6.18 - 2.6.30 with the error reoccuring. I tried everything I could, but no way. Any suggestions welcome, but thinking about switching to OpenVZ/XEN anyway :-/ Greets, Falk On Sep 30, 2009, at 8:50 PM, Flavio wrote: > Hi all, > > I have some networking problem. > Networking inside UML is always worked, but today it suddenly > stopped to work. > > The command line is the same I've always used: > linux ubd0=rootfs.debian.etch ubd1=swapfs.debian > eth0=tuntap,,,192.168.1.100 mem=512M > > During the boot of the virtual machine I get these messages: > Configuring network interfaces...SIOCSIFADDR: No such device > eth0: ERROR while getting interface flags: No such device > SIOCSIFNETMASK: No such device > SIOCSIFBRDADDR: No such device > eth0: ERROR while getting interface flags: No such device > eth0: ERROR while getting interface flags: No such device > Failed to bring up eth0. |

It depends on the root filesystem!!!!! I tried another root filesystem and the network works like a charm. But now... what could be happened to my filesystem?? Could it be some broken package? Flavio |
