    [SOLVED] no network after power fail

    Dear people, we have a Proxmox VM server here and after the UPS got out yesterday, it crashed hard. Since then the network no longer works. Quick to setup, this is a relatively small server, which is why it only has a NIC, it is connected to a managed switch and a hybrid port. The management...

    OPNSense VM Low Inter-VLAN throughput, SR-IOV the play?

    I am running an opensense VM in proxmox and while VM-VM throughput on the same VLAN can do ~32Gbps, routing across VLANs incur a 94% penalty dropping it to 2Gbps. I understand this is a limitation of emulating a L3 switch through software in which these devices typically have tailor-made ASICs...
