Hi Giuseppe, this is expected behavior, since you used VM with no operating system (OS) installed, hotplug feature need support from OS side. From design page http://www.ovirt.org/Features/Design/DetailedHotPlugNic This feature will be restricted to operating systems that support this action – Windows7, Windows7 x64, Windows2008, Windows2008 x64, Windows2008R2 x64, RHEL5, RHEL5 x64, RHEL6 and RHEL6 x64 Actually later on this restriction to certain OSes was removed, however support for hotplug from OS side is required. Hi Martin thanks for the explanation, from the error message that is not clear that is not supported. |
