Hello SmartOS users, We’ve encountered a problem, where NICs inside a guest KVM OS got renamed after a system update.
We are using RHEL/CentOS VMs and also provide some CentOS images. The recent 7.4 (1708) release of RHEL/CentOS includes an updated version of the cloud-init package, which renames NICs according to the nics.*.interface property, which is all right. However, the previous version of RHEL/CentOS included cloud-init 0.7.5 (officially released 2014-04-01), which ignored the nics.*.interface property and NICs were named eth<id>. The latest version of RHEL/CentOS has cloud-init 0.7.9 (released 2016-12-23). The SmartOS-related change happened in version 0.7.7 (released 2016-08-10). For all Danube Cloud users - the problem and fix is described here: https://github.com/erigones/esdc-ce/wiki/Known-Issues#network-down-in-vms-after-update-of-cloud-init-or-centos <https://github.com/erigones/esdc-ce/wiki/Known-Issues#network-down-in-vms-after-update-of-cloud-init-or-centos> We are sorry for any troubles caused by this issue.
