[Bug 1352732] [NEW] live migration fails:CPU feature `erms' specified more than once

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

When I live migrate VMs from one node to another(both are the same
species),  nova service at the destination node throws exception below,
my physical compute nodes are both ubuntu 14.04lts and openstack git
stable/icehouse

(I notice there are similar bug reports like
https://bugs.launchpad.net/nova/+bug/1303536, but the codes throwing
exception seem not the same )

/usr/local/lib/python2.7/dist-packages/nova/virt/libvirt/driver.py

4230         source_cpu_info = src_compute_info['cpu_info']
4231         self._compare_cpu(source_cpu_info)

Title:
  live migration fails:CPU feature `erms' specified more than once

Status in OpenStack Compute (Nova):
  New

Bug description:
  When I live migrate VMs from one node to another(both are the same
  species),  nova service at the destination node throws exception
  below, my physical compute nodes are both ubuntu 14.04lts and
  openstack git stable/icehouse

  (I notice there are similar bug reports like
  https://bugs.launchpad.net/nova/+bug/1303536, but the codes throwing
  exception seem not the same )
