Open Stack

Couple of questions,


-          Do you have n-cpu running in every node? (controller and both computes)

-          Which services do you have enabled in both compute nodes?

-          To which node corresponds the screen log provided?

-          What is the output of nova-manage service list?

Facundo.

First, please don't use all caps in your subject.  Second, please do use tags to indicate which projects your message relates to.  In this case, that appears to be nova.

As far as the error, it looks like you may have some out of date code.  The line referenced in the backtrace is now line 1049 in api.py, not 953.  That suggests to me that there have been some pretty significant changes since whatever git revision you're currently using.

Hi all
I have installed openstack using devstack and nearly all the functionality is working fine.
However I'm getting an issue during live migration .
I'm creating a stack of one controller node and two compute nodes i.e Compute node 1 and compute node 2 .I'm booting one VM at compute node 1 and need to migrate it over compute node 2.
For this I'm using NFS which is working fine.

Also I have enabled live_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_LIVE in /etc/nova.conf over both the compute nodes and over controller node.

However when I apply nova live-migration command after restarting the nova-compute service using screen session the VM is not able to migrate.
Below are the logs after restarting nova-compute service ..

Also find the attached screanshot describing the complete error.
Please help regarding this.
