Privacy Extension not working in VM
Hello @ all
With the rebuilding of my Server from Debian 9 to Debian 10, I also
switch from Virtual Box to Libvirt/KVM. Due to new requirements for the
VMs, now I have an actual problem, which unfortunately I can not solve.
The problem has already been discussed in the German Debian-Forum ...
unfortunately also without success.
The facts:
- ISP = Dual Stack with daily separation

newbee questions
...g with wifi NIC's on
the web made me, perhaps incorrectly here, assume that a wifi nic
might be an issue, so thats where the idea to use macvtap came from.
Manual setup of macvtap seems to work, as i can do this without issues
on a root prompt on the same machine:
ip link add link wlp2s0 name macvtap0 type macvtap
ip link set macvtap0 address 1a:46:0b:ca:bc:7b up
ip link show macvtap0
But the wifi interface 'wlp2s0' does not seem to show up in the ovirt
web gui interface.
Im sorry if I sound confusing here, but that may be just because im
really still confused about ovirt.
;)

Guests can't connect to each other
Hi,
I'm using libvirt and qemu on Debian Wheezy. I'm having a strange
behavior. Guests can't connect to each other when they're on the same
host.
On the host I'm using bonding (in active / backup mode) and vlan. It
looks like this :
eth0 \ / macvtap0
bond0 --- vlan222
eth1 / \ macvtap1
So I've got two guests, let's say A and B. When I try to ping B from A,
it works :
# ping -s 3000 -c 5 78.109.95.11
PING 78.109.95.11 (78.109.95.11) 3000(3028) bytes of data.

Problems with incoming multicasts
...My Setup is:
1 Host with 1 VM. On the external Network (Host: eth0), there ist a
Multicast Stream. The packages are visible at the hosts eth0. The Guest is
connected via macvtap to the eth0 from the Host.
Host and Guest ist CentOS 7.6 in Future it should be RedHat 7.6.
The guest is connected via macvtap0 to eth0.
If i performe tcpdump on eth0 of the host, i can see teh packages.
If i performe tcpdump on macvtap0 on the host, i can see the packages
anyway.
If i performe tcpdump on the guests eth0, i can't see the multicast
packages.
Normal unicast communications to the external systems are stil...

F20 Virt-Manager with MacVTap not working
Hello,
I've setup a VM with default networking (NAT) and this works fine but hosts
on my LAN can't get to the VM since it uses NAT.
When I try to set network to use MacVTap with either default or bridged I
get no networking for the VM.
Any hints around this? I would like to have the VM's on the same LAN as my
host and other machines. I don't care if the VM host can't reach the
