[PVE-User] Debian 7 guest losing network
elacunza at binovo.es
Fri Oct 2 09:07:38 CEST 2015
I do have some tens too, without problem except this one. I have moved
the VM to another physical server in the cluster in case there's some
kind of problem with the physical server or switch port (there are
another 2 VMs in that original proxmox node, but who knows...).
Evening and night have been good; I'll keep the list up-to-date on this
