    PVE nested in HyperV, PVE gets network access but PVE vm's do not (destination host unreachable). Looking for guidance to set promiscuous mode in HV.

    It looks like the topic of port monitoring is a bit above my current level of understanding and I haven't been able to find a concrete guide to help set this up. I have Hyper-V enabled on my Windows host and Proxmox is installed as a VM in Hyper-V. Proxmox was able to get a DHCP assigned IP...

Ideally I would not...

    Is it safe to disable vmbr0?

    We run a proxmox installation and our networking setup is VMs go over NAT on vmbr1. We want to disable vmbr0 due to VMs accidentally being created on vmbr0, and us getting MAC spoofing abuse reports from our server hosting provider. There seems to be no traffic over vmbr0. root@pve:~ # cat...
