Hi all, When I see dmesg on host machine it gives
error- “macvtap0: no IPv6 routers present” Is this error causing saome problem.. Even if guest starts it gives error “Bringing
up interface eth0: Device eth0 does not seem to be present, delaying
initialization. [FAILED]” Is this dmesg = - “macvtap0: no
IPv6 routers present” the cause??? From:
libvir-list-bounces@xxxxxxxxxx [mailto:libvir-list-bounces@xxxxxxxxxx] On Behalf Of Amit Tewari Hi all, Please ignore my previous mail.. This is my test scenario My test environment Host os=rhel6.1 Guest os = rhel6.1 Libvirt=0.9.8 Kvm hypervisor I am creating a macvtap interface on host machine at eth0
interface #ip link show macvtap0 51: macvtap0@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP>
mtu 1500 qdisc mq state UNKNOWN qlen 500 link/ether 1e:aa:f7:43:7e:3d brd
ff:ff:ff:ff:ff:ff I have made this entry in guest xml file <interface type='direct'> <mac
address=1e:aa:f7:43:7e:3d’/> <source dev='eth0'
mode='bridge'/> <model type='virtio'/> <address type='pci'
domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> Now when I start the guest #virsh start guest It gives following message error: Failed to start domain guest error: Cannot set interface flags on 'macvtap1': Device or
resource busy Please let me know what else we need to do to make macvtap
work on kvm. From:
