After the last update of today in Centos 7.5, the virtual machines hosted in Proxmox 3.4 have lost the network and only lift 3 processes, so they remain 100% inaccessible. In addition to Proxmox 3.4 I have virtualizations with Proxmox 5 (I do not know if this version happens) and OpenVZ7, which has also happened but there is already a solution. In the OpenVZ7 forum the solution is posted by me. (I can not put the link for being a new user.) Is any solution known in Proxmox 3.4 for this problem? Indicate that recovering a backup of the directories / etc / and / usr / the problem is solved but it is not detected which package is the one that fixes the problem. Thank you!
