Hi, Just as FYI, we recently upgrade from 6.5 to xs 7.1, so far everthing is good. Then we add some hosts to Pool or reinstall some XenServer to have proper new filesystem on dom0 which have more disk space for /var/log! then we ran into the situation where CloudStack fail to create Virtual Router in a XenServer cluster. Turns out that for some unknown reason, adding a fresh installed xenserver to a cluster can create new SR and VDI for xs-tools iso, this break cloudstack VR creation for some reason. So the easy fix is to forget non-shared SR containing xs-tools VDI.
Basically, if "xe vdi-list is-tools-iso=true" return more than one iso, CloudStack should fail to create Virtual-Router.
