Hi Rohit, forgot to answer you on the cloud.vlan table.
That particular vm has a network with vlan id 1151 as shown when i look at the network details in the acs gui. However, this vlan is not shown in the cloud.vlan table. From what I can see the cloud.vlan table shows only the public and management network vlan interfaces and does not show the guest network vlans. In terms of the public network vlan which is used for routing traffic to the internet from this particular vm, it is: mysql> select * from vlan where id=12; +----+--------------------------------------+-------------+---------------+-----------------+-------------------------------+----------------+----------------+------------+---------------------+-------------+----------+-----------+---------+---------+ | id | uuid | vlan_id | vlan_gateway | vlan_netmask | description | vlan_type | data_center_id | network_id | physical_network_id | ip6_gateway | ip6_cidr | ip6_range | removed | created | +----+--------------------------------------+-------------+---------------+-----------------+-------------------------------+----------------+----------------+------------+---------------------+-------------+----------+-----------+---------+---------+ | 12 | d13ea4b3-2087-4376-9d0a-f54efe2a55af | vlan://2030 | 178.XXX.XXX.1 | 255.255.255.128 | 178.XXX.XXX.2-178.XXX.XXX.119 | VirtualNetwork | 1 | 200 | 200 | NULL | NULL | NULL | NULL | NULL | +----+--------------------------------------+-------------+---------------+-----------------+-------------------------------+----------------+----------------+------------+---------------------+-------------+----------+-----------+---------+---------+ 1 row in set (0.00 sec) Hope that helps Andrei ----- Original Message ----- From: "Rohit Yadav" <rohit.ya...@shapeblue.com> To: users@cloudstack.apache.org Sent: Wednesday, 13 May, 2015 8:55:55 AM Subject: Re: ACS 4.5.1 KVM live migration problem Hi Andrei, This looks like an issue similar to https://issues.apache.org/jira/browse/CLOUDSTACK-6893 Can share the row from your cloud.vlan table and value of “select cache_mode from volume_view where vm_id=<put the vm id here>\G;" for the VM causing the NPE? > On 12-May-2015, at 10:51 pm, Andrei Mikhailovsky <and...@arhont.com> wrote: > > > > It seems that the problem is worse than i've initially thought.
