The culprit was rx-gro-hw ... generic-receive-offload on BROADCOM NICs (latest Firmware 22.92.07.50) with Kernel 6.8 Here is what I guess happend: I did not realize the bad RX Performance after Upgrading to PVE 8, because the problems shows only in specific conditions. 1. Docker inside VM ->...

OK, thanks and sorry for being judgemental. This is exactly what im doing. But they need a route to the outside world again. Thats where my gateway comes in. I dont think the SDN approach will solve this. I currently suspect something wonky in our backbone-network or the ISPs network. I will...

Hey Juliosene, the motivation is to use a lower amount of public IPv4 addresses. I have got a /25 net with public addresses and it is getting full. 1. Yes 2. No 3. VLAN 100 Private (192.168.1.0/24) and VLAN 999 is public from my /25 net. 1. There is no dual WAN, nor is it needed! 2. I dont...

Thanks for your input anyway! :)

Bond mode is LACP with layer 2+3 Unfortunately there is no such thing state in the log. Neither "duplicated" nor anything mentioning "mac" or mac adresses. :-(

Hey Proxmoxers, im facing a weird problem. Proxmox Version 8.2.4. I have a bond0, which is split into vlans. I have vmbr0 which is VLAN aware. Lets say i have a private network 192.168.1.0/24 and some VMs there with a virtio NIC with vlan tag 100. Now I am adding another VM, that has two...

it was an ip address conflict... It was a IP on the switch itself for debugging purposes in that network, that hasnt been removed by the network-admin after the debugging....

i cant really narrow down to what it is. We've redone the switch config and the local network configs. Sometimes ssh just works and other times it doesnt. When it works, its says debug2: peer server KEXINIT proposal debug2: KEX algorithms...

Thanks for your input! Yes, this is what I initially thought too. But no, unfortunately not. At this point I'm glancing towards broken tranceivers/nics/switchports... I've had this problem before with the same node. I did a fresh reinstall and the same problem is coming up again. I am going...

that is odd, they are allowed and its only one out of 8 identical installations, that shows this behavior. And also, it is not permanently, sometimes it works, sometimes it doesn't.

Hey all, one of my nodes is causing my cluster to break sync every now and then. When that is happening, it usually does not want me to access it via SSH and gives this error: Unable to negotiate with 10.168.61.21 port 22: no matching key exchange method found. Their offer...

on the network device you mean? How should that affect the underlying NFS? Client -> SSH -> Container -> fio-command -> IOs towards NFS. If you are talking about the network device, then it would only affect the "client -> ssh" part.

i can reliably crash my system if i put IO load inside a container that has its image as raw on the nfs share...

Dear Proxmoxers, i have two boxes, one is running truenas with ZFS RaidZ1 and exporting via NFS. The other one is running Proxmox 7.2. (pve-host) If I am running i.e. fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --bs=4k --iodepth=64 --readwrite=randrw...

Hi, I accidentally found a workaround. Usually there is a regular disk created with the VM. The default size for a Win10 VM is 32GB. Delete/Detach this disk. Boot the machine, go into the EFI settings, change the boot order again and voilá, it works. Best regards inDane

Hi fellas, im using OVMF (UEFI) and id like to boot directly from a NVMe drive, which is passed-though. it basicly works, but not automatically. I don't know where to change it. If i change anything in the boot menu of EFI, it will "forget" it at next boot of the VM. I can manually boot it via...

oh my god, i've spent so much time. Thanks, this is the solution! WRONG RIGHT video=vesafb:off video=efifb:off

I've had no success. Thank you very much for your input. To not extend this any further, i just grabbed an RX 480 from another computer and installed it with that one.

nomodeset ... doesnt show these artifacts on the screen, but it wont continue either. It shows that it got an IP via DHCP and now it just sits there.

Maincomponents are: - Ryzen 3950X - ASUS X570 ROG x570-F - Nvidia RTX 2060 Super (Gigabyte) you mean, with "e" going to the edit the boot menu and add vga=791 to the line, starting with /boot/linux26, right? That didn't help unfortunately. Do you have more ideas I could try? Best
