[libvirt] FW: macvtap not working on rhel 6.1 x86 machine
Hi all, My test environment Host os=rhel6.1 x86 machine Guest os = rhel6.1 Libvirt=0.8.7 Kvm hypervisor I am creating macvtap interface on host machine ip link add link eth1 name macvtap0 type macvtap ip link set macvtap0 up ip link show macvtap0 25: macvtap0@eth1: BROADCAST,MULTICAST,UP,LOWER_UP mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 500 link/ether a2:70:4e:05:4a:4e brd ff:ff:ff:ff:ff:ff Now when use arp -a to check macvtap0 hardware address entry it shows ? (10.0.7.1) at incomplete on macvtap0 If I assign ip address to macvtap and then ping on network , it says destination not reachable ping 10.0.7.1 -I macvtap0 PING 10.0.7.1 (10.0.7.1) from 10.0.1.61 macvtap0: 56(84) bytes of data.

Here (http://libvirt.org/formatdomain.html) you will find the following xml sample, which works: ... devices interface type='direct' source dev='eth0' mode='vepa'/ /interface /devices ... This will connect your VM directly to the same network as eth0. Please be aware that, depending on your switch configuration (supports hair pin mode or not), your host might not be able to talk to your VM and vice versa. -- Best regards, Gerhard Stenzel, --- IBM Deutschland Research Development GmbH Vorsitzender des Aufsichtsrats: Martin Jetter Geschäftsführung: Dirk Wittkopp Sitz der Gesellschaft: Böblingen Registergericht: Amtsgericht Stuttgart, HRB 243294 DISCLAIMER: --- The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.

Re: [libvirt] macvtap nt working on kvm
Hi, Actually macvatap doesn't work with bridge. So once the physical device is attached to a bridge, a macvtap attached to that device no longer works. In my case there is no bridge on the interface. but still guest os is not able to get ip address.

[libvirt] New feature for libvirt network filter
Hi, I wanted to suggest a new feature in libvirt network filter. Currently libvirt allow only one ip address to be provided in the guest configuration xml file. We should allow multiple ip addresses to be provided statically in the guest xml for an interface, so that packets matching either of these multiple ip addresses should be allowed to be routed out from the guest machine.

[libvirt] New feature for libvirt
Hi, I wanted to suggest a new feature development in libvirt network filter. Currently in libvirt network filter there is no support for ip aliasing, but we want to add this feature so that libvirt learns multiple ip address for a virtual machine. With this feature we will be able to get no-ip-spoofing filter works on machine with ip aliasing. Currently if we apply no-ip-spoofing filter on a virtual machine with ip aliasing then only one ip address is earned by libvirt ,due to this other aliased ip address packets are not allowed to route out of the machine.
