Fixed In Version: openstack-nova-15.0.7-1.el7ost
Doc Type: Bug Fix
Doc Text:
This update fixes a bug that prevented the 'cache' mode of volumes from being set correctly during live migration. Previously, the cache mode of a volume could get changed to 'cache=none' during live migration, resulting in high I/O latency; to work around this, users had to reboot the instance.
