Package: xen-utils-common
Version: 4.0.0-1
Severity: important
Tags: patch
--- Please enter the report below this line. ---
when you use "hardware" virtual machine (with qemu) with xen
configured for bridging
the network script treates a tap interface and then
/etc/xen/scripts/qemu-ifup adds it to the bridge.
That would be ok but tap interfaces have a random mac address and the
bridge always gets tha lowest mac address.
considered dom0 uses this bridge, this can lead to a loss of network
connection.
The probability of getting this problem changes with the real mac
address of the main interface.
(No chance mine starts with "BC" )
A nice solution is to change the mac address of the tap interface to
some very high and unlikely value before it is added to the bridge.
Here is my version of /etc/xen/scripts/qemu-ifup
It has some logs inside that can be removed but I feel it useful for
checking.
#!/bin/sh
echo -c 'config qemu network with xen bridge for '
echo $*
