Hi all, In same previous scenario of macvtap ,Im
not able to assign dhcp address to guest interface, and if I assign static ip
of my lan to guest interface , than also it is not able to connect to the
network.. From: libvir-list-bounces@xxxxxxxxxx
[mailto:libvir-list-bounces@xxxxxxxxxx] On
Behalf Of Amit Tewari Hi, Actually udev renames the eth0 interface
in guest to eth1 because macvtap0 has different mac address then eth0 on host..
Is there some way so that we can prevent
changing this rename of eth0 to eth1 on guest. I don’t want to change
udev files. From: xhu [mailto:xhu@xxxxxxxxxx] On 12/13/2011 12:59 PM, Amit Tewari wrote: Hi all, My test environment Host os=rhel6.1 Guest os = rhel6.1 Libvirt=0.9.8 Kvm hypervisor I have made this entry in guest xml file <interface type='direct'> <source dev='eth0'

below #ip link show

ff:ff:ff:ff:ff:ff but when the guest is up and I try to perform # ifup eth0 It gives following message “Bringing up interface eth0: Device eth0
does not seem to be present, delaying initialization. [FAILED]” The interface name may
change to ethN(N may be 1 or 2 ...) due to the change of guest interface mac
address. Guest eth interface does not create. What is the
problem? When I checked dmesg
on host it gives following message—“macvatp0: ipv6 routers not
present” Please let me know how macvtap work on kvm.
