Pkg xen devel - Jun 2012 - Bug#677509: xcp-xapi: migration of PV linux does not produce grace ARP

Package: xcp-xapi
Version: 1.3.2-6
Severity: important

Configuration: 

Two xcp-xapi hosts (default sid/xcp-xapi installation) in single pool. 
Network backend is bridge.

After migration of 'idle' (doning nothing) virtual machine it stops to
reply
to ping for long time.
AFAIK that caused by mac-learning table on upper level (hardware) switch, 
which route all frames to wrong port (ignoring migration).

Usually this solved by sending 'grace ARP', allowing switch to learn 
new port for same MAC address.

I'm not sure if guest kernel or virtualization toolstack is response for
this.

Tested with template 'Debian Squeeze 32', upgraded to sid.

Guest kernel: linux-image-3.2.0-2-686-pae

-- System Information:
Debian Release: wheezy/sid
  APT prefers unstable
  APT policy: (500, 'unstable')
Architecture: i386 (i686)

Kernel: Linux 3.2.0-2-686-pae (SMP w/8 CPU cores)
Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8)
Shell: /bin/sh linked to /bin/dash

OK, sorry, it was error in second host configuration. Migration works fine with
linux-3.2
