[Bug 551549] [NEW] KVM vde2 support not working

[Christian Roessner]

Public bug reported:

Binary package hint: qemu-kvm

Starting a kvm guest with:

cat karmic 
vdekvm \
  -m 256M \
  -cpu host \
  -smp 1 \
  -name karmic \
  -boot order=nc \
  -drive file=/dev/vg01/test,if=virtio,boot=on,cache=none \
  -net nic,vlan=0,macaddr=00:2f:8d:b6:cf:d0,model=virtio \
  -net vde,vlan=0,sock=/var/run/vde2/vde0.ctl \
  -watchdog i6300esb \
  -vnc :0 \
  -serial telnet:localhost:23,server,nowait \
  -monitor tcp:127.0.0.1:12000,server,nowait \
  -runas kvmguest

shows:

NOTE: vdekvm is now DEPRECATED -- both QEMU and KVM have native support for
      VDE. This binary will be removed soon from the distribution, consider
      stopping using it.

arg ,vlan=0,sock=/var/run/vde2/vde0.ctl
TUNGETIFF ioctl() failed: Invalid argument
TUNSETOFFLOAD ioctl() failed: Bad address

Changing vdekvm to kvm:

sh karmic-guest-script 
Invalid -net type 'vde'

The manpage already shows option vde, while the kvm-binary does not:

kvm --help
...
Network options:
-net nic[,vlan=n][,macaddr=mac][,model=type][,name=str][,addr=str][,vectors=v]
                create a new Network Interface Card and connect it to VLAN 'n'
-net user[,vlan=n][,name=str][,net=addr[/mask]][,host=addr][,restrict=y|n]
         [,hostname=host][,dhcpstart=addr][,dns=addr][,tftp=dir][,bootfile=f]
         [,hostfwd=rule][,guestfwd=rule][,smb=dir[,smbserver=addr]]
                connect the user mode network stack to VLAN 'n', configure its
                DHCP server and enabled optional services
-net tap[,vlan=n][,name=str][,fd=h][,ifname=name][,script=file][,downscript=dfile][,sndbuf=nbytes][,vnet_hdr=on|off]
                connect the host TAP network interface to VLAN 'n' and use the
                network scripts 'file' (default=/etc/qemu-ifup)
                and 'dfile' (default=/etc/qemu-ifdown);
                use '[down]script=no' to disable script execution;
                use 'fd=h' to connect to an already opened TAP interface
                use 'sndbuf=nbytes' to limit the size of the send buffer; the
                default of 'sndbuf=1048576' can be disabled using 'sndbuf=0'
                use vnet_hdr=off to avoid enabling the IFF_VNET_HDR tap flag; use
                vnet_hdr=on to make the lack of IFF_VNET_HDR support an error condition
-net socket[,vlan=n][,name=str][,fd=h][,listen=[host]:port][,connect=host:port]
                connect the vlan 'n' to another VLAN using a socket connection
-net socket[,vlan=n][,name=str][,fd=h][,mcast=maddr:port]
                connect the vlan 'n' to multicast maddr and port
-net dump[,vlan=n][,file=f][,len=n]
                dump traffic on vlan 'n' to file 'f' (max n bytes per packet)
-net none       use it alone to have zero network devices; if no -net option
                is provided, the default is '-net nic -net user'
-netdev [user|tap|socket],id=str[,option][,option][,...]
...

So the package seems only to be built partially against vde?
