    qm remote-migration - 400 Parameter verification failed

    Wierd, wonder why there's the "--online" options then. But that worked for that one, but the next one I attempted with the VM running gives the same error as the previous with the VM stopped. Edit: Never mind, that VM had an unused disk associated with it which caused the error. This stuff...

    qm remote-migration - 400 Parameter verification failed

    I'm trying to migrate some VM's from an old server to a new one and I'm getting the following error and dispite searching, I've no idea what's going wrong. ERROR: migration_snapshot: type check ('boolean') failed - got '' My migrate command looks like this some values <redacted>: qm...

    Proxmox generate 2 mac address visibile on the switch not allowed by the data center

    So what's the problem with having a firewall rule that drops everything not addresses to one of your IP addresses? And yeah, the whole my MAC other persons IP is something weird Hetzner does, but they aren't going to fix it, so we have to work around it.

    Proxmox generate 2 mac address visibile on the switch not allowed by the data center

    Define an IPSet and add each of your IP addresses making sure the "nomatch" check box is ticked for each item. Then you just add your DROP rule with destination set to your IPSet.

    Network trouble with Hetzner subnet

    I don't know if this helps, but I have a rule at the datacenter, host and each VM/CT that drops incoming traffic addresses to ip addresses that are not one of the ones assigned to me. (Define and ipset of your assigned addresses then drop anything not addressed to something in that ipset). I...

    [SOLVED] Failed to reach Proxmox on VLAN

    The post-up occurs after link is established on vmbr0 (via enp2s0). In this case it's re-enabling wake-on-lan on the hardware port (which for some reason gets disabled on my hardware after you use WOL to wake the server. (the local power sub-station has a bad habit of blowing a fuse so the...

    Network trouble with Hetzner subnet

    Are you running PVE 7? There was an issue with 6 and earlier with PVE reflecting messages sent to it with another machines MAC address (IIRC, it's been a while) which causes Hetzner to send abuse messages, but that should have been fixed in 7 (and I haven't seen it since then).

    [SOLVED] Networking Troubleshooting help

    This looks ok so far (except I'd give your pfsense WAN a static IP address). If you can go from pfsense to devices on the 192.168.2.0/24 but not from the network to pfsense, it's probably a firewall rule issue. Check both the firewall for the VM on proxmox and the rules within pfsense itself...

    [SOLVED] Failed to reach Proxmox on VLAN

    Here's how I've set up VLAN's on my servers, and I use Ubiquiti switches too, so this works with them. This gives you VLAN's 10 and 666 ( a VLAN for naughty devices that misbehave). Just change the numbers after the "vmbr." to change the VLAN number. iface enp2s0 inet manual auto vmbr0 iface...

    Network setup for Hetzner

    Have you enabled IP forwarding? See "Enable IP Forwarding on the Host" in this documentation Also, remember that the VM should have the IP address of the proxmox interface as the gateway. Alternatively, use bridged networking, it's easier to set up.

    Network trouble with Hetzner subnet

    With regard to the MAC issue... For individual IP addresses, Hetzner requires you to use specific MAC addresses specified in the "IPs" section of the server information on the Hetzner Robot website. They may have extended this policy for routed subnets (they didn't the last time I had a routed...

    Rate limit a VLAN / Linux Bridge

    Is there any simple way to rate limit a VLAN and Linux Bridge under proxmox? For example, say I have a bridge vmbr0 and a vlan vmbr0.2 on a 2.5Gbe port and I want to limit the vlan so it never uses more than 1Gb/s on the port in either direction. I'm using Proxmox VE 8.2.2 but I'm not using...

    Metric Server data documentation

    After a whole bunch of testing, I'm pretty sure that the receive and trasmit values in the nics measurement set are recorded in bits/s, otherwise I'm able to do 10Gb/s speed over a 1Gb/s network interface. The diskread and diskwrite I'm not so sure of. Even in bits/s it seems to be over...

    Prune Simulator Question

    I've been using the prune simulator to figure out a decent backup schedule and I've come across something I don't understand. The image below shows a daily backup with the following: keep_daily 7, Keep_weekly 4, keep_monthly 4, keep yearly 2. The monthly backup appears to be kept for the last...

    Proxmox generate 2 mac address visibile on the switch not allowed by the data center

    If you aren't already on proxmox 7, upgrade. That fixed this issue for me at Hetzner. Edit: Be careful and read the notes before upgrading! You have to set your MAC address in the IPv4 network config (you probably want Solution B) otherwise you'll end up locked out (unless you've also...

    What are fwbrXYZi0 and fwlnXYZi0 and why are their MAC addresses being seen by Hetzner?

    Hi Spirit, Thanks for the response. I think the easiest thing will be to upgrade to proxmox 7 if that solves the problem. Thanks.

    What are fwbrXYZi0 and fwlnXYZi0 and why are their MAC addresses being seen by Hetzner?

    i All, I have a proxmox 6.4-13 server running in a Hetzner datacenter with Bridged networking (redacted config below). I currently have 5 VM's running and each VM has a MAC address (in the running OS) starting with 00:50:56. When I do an ifconfig on the host machine, each VM has an...

    My Proxmox cannot PING anything

    I'm a little confused by this since you don't mention "the box" or the 192.168.1.100 address anywhere else. Are you virtualizing Proxmox inside another hypervisor? Assuming 192.168.1.1 is your router and that other machines on your network have full internet access, is it possible you've...

    Proxmox generate 2 mac address visibile on the switch not allowed by the data center

    If I was bridging enp2s0 (or in my case enp0s31f6) with vmbr0, would the post-up rule need be done on the interface, bridge or for the host and each VM? And would just ommiting the "-p IPv4" make this work for dual IPv4/IPv6 network stacks too? For reference, my network config is: auto lo...
