Hi All,

I am using openstack Mitaka release(One node setup,created on ~14.04.1-Ubuntu ). Currently i am facing issue while instantiating a VM using QCOW2 image (Ubuntu14.04+sw package), wherein i am getting below error while accessing VM console:

error:couldn't find suitable memory target unaligned pointer 0xff85c389

We tried tweaking some parameter related to libvirt/KVM in nova.conf as suggested in below mentioned url :

https://wiki.openstack.org/wiki/LibvirtXMLCPUModel (https://wiki.openstack.org/wiki/Libvi...)

[libvirt] libvirt_cpu_mode = custom libvirt_cpu_model = SandyBridge

No significant Error in nova logs:

We faced similar issue in one of our setup and found that the flavor which we were using had only 8MB of RAM allocated to it, which was a typo while creating the flavor.

Post increasing the memory size we were able to launch the VM
