Dotaz: Jak pridat wifi sitovou kartu do virt. stroje v KVM

[polo23]

Ahoj,

chtel jsem se zeptat zda se nekomu z vas podarilo uspesne pridat wifi sitovou kartu do virtualniho stroje v KVM. Mne se to nedari a reseni jsem taky nevygooglil.

Mam Os Debian Squeeze, wifi Intel PRO/Wireless 5100 AGN, virt stroj je taky Squeeze.

Instaloval jsem ho tak ze br0 bylo eth0, ale po prepsani /etc/network/interfaces do nasl. podoby
/etc/network/interfaces

auto br0
iface br0 inet dhcp
        bridge_ports wlan0
        bridge_fd 0
        bridge_hello 2
        bridge_maxage 12
        bridge_stp off
        bridge_maxwait 0

skoncilo spousteni stroje s nasl. chybou.

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 808, in run_domain
    vm.startup()
  File "/usr/share/virt-manager/virtManager/domain.py", line 1296, in startup
    self._backend.create()
  File "/usr/lib/python2.6/dist-packages/libvirt.py", line 333, in create
    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: internal error Process exited while reading console log output: char device redirected to /dev/pts/2

prikladam jeste vypis ip

2: eth0: BROADCAST,MULTICAST,UP,LOWER_UP mtu 1500 qdisc mq state UP qlen 1000
    link/ether 00:1c:25:95:20:bd brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.254/24 brd 192.168.1.255 scope global eth0
    inet6 fe80::21c:25ff:fe95:20bd/64 scope link 
       valid_lft forever preferred_lft forever
3: wlan0: BROADCAST,MULTICAST mtu 1500 qdisc mq state DOWN qlen 1000
    link/ether 00:16:ea:bb:bd:54 brd ff:ff:ff:ff:ff:ff
15: br0: BROADCAST,MULTICAST,UP,LOWER_UP mtu 1500 qdisc noqueue state UNKNOWN 
    link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::3496:a6ff:fea8:eae0/64 scope link 
       valid_lft forever preferred_lft forever

Budu vdecny za kazde nasmerovani. To o co mi jde je spustit virt. stroj a mit v nem dostupnou wifi sit. kartu.

Ahoj, vypadá to, že přidat wifinu do bridge je krajně problematické, viz http://www.linuxfoundation.org/collaborate/workgroups/networking/bridge#It_doesn.27t_work_with_my_Wireless_card.21. Sám jsem na tento problém narazil na laptopu taky, obešel jsem to přes virtuální síť (ve virt-manageru lze naklikat).
