Package: xen-hypervisor-4.0-amd64
Version: 4.0.1-4
Severity: normal

atalkd appears to be unable to open virtual network interfaces when
run in a Xen PV guest.
With nothing set in atalkd.conf, it reports :
eth0: disabled.
atalkd: zero interfaces, exiting.
Adding "eth0" to atalkd.conf results in :
eth0: Invalid argument
Can't configure multicast.
eth0: disabled.
atalkd: zero interfaces, exiting.
If the entire VM is moved to a physical host (ie running native with
no virtualisation), then atalkd works as expected. This physical
machine has a GeForce chipset and the forcedeth network driver. the
only changes were to use eth1 instead of eth0, and make the system
bootable with GRUB.
Suggestion from netatalk maintainer is that atalkd requires multicast
support - but this is not provided by Xen virtual NIC/driver.
