Hi all, I just installed Xen 3.0.1 on RHEL 4.1. Bringing up dom0 and a domU worked fine. But when I want to restore a previously saved domU, it doesn't come up any more. Reading the logfiles, it seems that xen had problems initializing the domU's virtual nic. Does anyone have a clue what could be the reason for this?
