Exactly, I mean 10Gbit fiber transceiver. If I test the same vlan, I've got 10Gbit transfer, but if I use 2 different vlans, I've got only 1Gbit.

I've set up serial port for vm and it works correctly but I can get proxmox console to view my machine (there's "unable to find a serial interface" error on start proxmox console). It's Windows 10 so I get it by remote desktop. Is it possible to using serial port passthrough and proxmox console?

I'm trying to understand how routing in Proxmox works but I can't. I set bridge vmbr1 on sfp for vm so it should communicate via sfp but it doesn't it. My default bridge (vmbr0) is on ethernet and I suppose that it routes all traces via ethernet and I've got only 1Gbit testing iperf. Should I...

Network driver is virtio, Windows 10 & 2012R2, I've tested it with iperf (simply client-server connection).

I've only changed vmbr0v10 to vbr0.10 in /etc/network/interfaces and restarted the networking service. edited: I know the reason, I've changed in /etc/network/interfaces but I didn't know that it changes linux bridge to linux vlan. I should remove bridge_stp/bridge_ports/bridge_fd settings from...

Hello, can anybody explain me (or help to fix) low performance on Windows VMs using sfp+ connection? Linux VMs have about 6Gbps/sec with iperf, but Windows VMs can get only about 2Gbps.

I think it's the point. Communication is over sfp, but that "bad" subnet is non-vlan class other than vlan on iperf server and routing goes by router which is not connected by sfp yet :) (Client is on 172.16.1.0/24 and server on 172.16.0.0/24)

I've got such scenario to analyze, I don't understand what I've done wrong, maybe it's a bug. My configuration of network in PVE: eno1 - ethernet interface (1Gbit) vmbr0 - main bridge connected to eno1 with ip address ens2f0 - sfp+ interface (10Gbit) ens2f0.10 - vlan 10 on interface ens2f0...

My PVE worked correctly only short time. Then the names of VMS/storage/etc dissapeared from GUI and I have no contact with VMs and storage. What did I wrong? How to correct it?

No, I haven't got cluster. I think that renaming node with running cluster would be stupid and unreasonable ;) By the way, I've revert any changes, restart and I've got running pve with old name. I'm so scared now to change name again.

Maybe it's too riskful to change node name if I've got a lot of vms ...

I did it step by step and something get wrong edit. Now I'm thinking that was not step by step, firstly I've renamed host and changed /etc/hosts and rebooted pve, then I've renamed /var/lib/rrdcached/db content

I've changed name for node and I'm totally stuck. Can't start any machine, can't get any storage. It look like this: proxmox is the old name, pve1 is the new name. Anybody can help me?

If I change vmbr0v10 to vmbr0.10 I got error while networking restart: mtu less than device minimum . What I should change?

I've configured with vlan, not vlan aware so I didn't mention second method (vmbr0.5) :) Thank you for explanation.

Thanx. So why you use auto vmbr0v5 iface vmbr0v5 inet static in configuration?

My /etc/network/interfaces file: iface ens1f0 inet manual iface eno1 inet manual iface eno2 inet manual iface eno3 inet manual iface eno4 inet manual iface ens1f0.10 inet manual iface ens1f1 inet manual auto vmbr0v10 iface vmbr0v10 inet static address 172.16.0.14/24...

I've set my proxmox as is written at https://pve.proxmox.com/wiki/Network_Configuration and it works correctly, host gets address from VLAN but in the GUI I see unkown type of bridge (it's named vmbr0v10) and can't edit it from GUI. Is it possible to set VLAN for host directly from GUI, not...

Sorry if my question is dumb but I'm newbie in Proxmox. I've connected proxmox host with SFP+ to LAN. My question is will I get 10Gbit transfer on VM if I'll bridge that interface for VMs or I should configure it other way?

I've clustered 2 nodes and after that I've got Result verification failed when I click on Disks/Directory on node 1. I've created there one directory for vms & isos. What should I check? I'm new in Proxmox. Any help very appreciated.
