Live migration on VMware rarely fails with such a smal= l VM like the VR is, with low RAM and no I/O. The current implementation do= es a router restart in every case just to make "sure" config is there. This= causes downtime up to 30 minutes in production environments. > Therefore I suggest to revert the changes in 4.5.2 and 4.6. > Also see ML thread in dev http://mail-archives.apache.org/mod_mbox/clouds= tack-dev/201506.mbox/%3C2D22E663-AFC2-4292-B16A-F6C2FCA0C217%40shapeblue.co= m%3E -- This message was sent by Atlassian JIRA (v6.3.4#6332)
