To start, we have recently migrated two older physical servers from Ubuntu 12.04LTS to CentOS as follows:
HP Proliant DL360 GEN5 | Running: CentOS 6.9 (CentOS 7 did not support the RAID controller)
HP Proliant DL360 GEN6 | Running: CentOS 7.3 1611
Both servers are configured as KVM hosts within Cloudmin.
While testing these two newly migrated servers, we created a CentOS7 Minimal KVM system from the following ISO:
Once setup, we configured it to have a status of "Webmin". We then shut the KVM system down, with a plan to clone it. When trying to clone it however, it will not clone to any of the hosts in our KVM hosts infrastructure, it just sends back the following error:
".. failed : Host system hostname.domain does not have any automatic IPv6 allocation ranges defined, but no v6 addresses were supplied for the clone"
I'm not sure what to troubleshoot here. We have other KVM VMs shutdown setup as "templates", and they seem to clone between hosts without issues. Any support/feedback on why this may be happening would be appreciated. Please just let me know what other information would be pertinent to resolving this.
