Re: [Xen-users] problem after migration

[Paras pradhan <pradhanparas@xxxxxxxxx>]

well arp not might be the case in here.

The problem is  similar to what has already been filed at bugzilla

https://bugzilla.redhat.com/show_bug.cgi?id=613513

I am still looking for the temporary solution if its the bug while
waiting for its solution.


Thanks
Paras.
