Hello, I am using VDE networking for my kvm-VMs. The kvm versions from the Ubuntu repositories still don't support VDE nativly. So i am forced to use the vdeq/vdekvm wrapper to start my VMs. Since I now upgraded my Ubuntu system from Jaunty to Karmic I have a weird problem. When launching a VM, two vdekvm processes get started. One with the vde configuration and one with a 'dummy' tap interface, that i don't want. I have no clue why this second process gets started. Have a look at the bash output: ------------------------------------------------------------------------- markus@kvm-host:/kvm/images$ vdekvm -hda win7.img -net nic,macaddr=00:31:5e:ef:e8:be,model=virtio -net vde,sock=/home/markus/vde_network/switches/sw-data.ctl -snapshot & [1] 3662 markus@kvm-host:/kvm/images$ arg ,sock=/home/markus/vde_network/switches/sw-data.ctl TUNGETIFF ioctl() failed: Invalid argument TUNSETOFFLOAD ioctl() failed: Bad address markus@kvm-host:/kvm/images$ ps aux | grep vdekvm markus 3662 0.0 0.0 19052 836 pts/1 S 02:09 0:00 vdekvm -hda win7.img -net nic,macaddr=00:31:5e:ef:e8:be,model=virtio -net vde,sock=/home/markus/vde_network/switches/sw-data.ctl -snapshot markus 3668 71.3 1.6 304260 137592 pts/1 Sl 02:09 0:07 vdekvm -hda win7.img -net nic,macaddr=00:31:5e:ef:e8:be,model=virtio -net tap,vlan=0,fd=3 -snapshot markus 3680 0.0 0.0 7336 892 pts/1 S+ 02:10 0:00 grep vdekvm markus@kvm-host:/kvm/images$ ------------------------------------------------------------------------- I am used to the TUNGETIFF error. This should be a bug in vdeq - the vde-network is working properly. I am more concerned about that second process with the default tap device. I am considering to update kvm manually to the newest version (0.12.3 if i am right). I hope both the TUNGETIFF as the error with the second process may disappear. Do you think i should try that / what might be the problem? May someone help me briefly on how to update kvm to the newest version with native vde support under Ubuntu, to get rid of the wrapper scripts? Any help appreciated!
