Hi all, We are working on nova live-migration using Ceph and trying to work around the problem where vm migration fails if name resolution is not enabled in a cluster. See the link, https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/... We have managed to work around this by setting the flag to include “VIR_MIGRATE_TUNNELLED”. However, it is noticebaly slower than non tunnelled. We were hoping that setting the listen_addr would get libvirt to return the listen_addr rather than the hostname but virGetHostname in libvirt/src/util/virutil.c doesn’t have access to the config structure. I was wondering if libvirt can be patched in a way to return the ip address of the destination instead of the hostname during migration? Regards, Yagmur Akbulut
