I have read that many had issues with proxmox 6/7 and OVS was unstable, is it possible to use OVS with proxmox 8.0 without any issues?

Hi, I have read your documentation and it says it's possible to run multiple clusters in the same datacenter: Multiple Clusters in the Same Network It is possible to create multiple clusters in the same physical or logical network. In this case, each cluster must have a unique name to avoid...

What ever you do don't upgrade to the latest version of proxmox ve 7.2.11 because it has iops issues.

Hi, I have some strange problem with my proxmox v5 cluster after i added a new machine for about 3 weeks ago. After a week the server have start giving ms spikes up to 1000 ms, and this is only happen when i see that the pvestatd is giving about 100% cpu in top of the server. This server is...

@mira any other suggestion ?

Please set this as resolved :-)

One question, have you added the Cloud-init drive mapped to your virtual machine ? Also check if you are running virtio driver for network.

I did try that, but nothing :/ it still don't doing anything when it boots up. I tried to run cloud-init clean and also remove the cloud-init and reinstalled it once again without any success.

Hi, I have a significant problem regarding ubuntu. All other template i have created are working just fine but this one doesnt. It feels like the mount of cloud-init drive doing nothing at the boot up of the vm. This is my cloud-init config and for me it looks fine: cat /etc/cloud/cloud.cfg...

Hi Alwin, It took about 20 minutes until iptables release the state, so i think i can live with that. Thank you so much.

Yup i have added it to /etc/modules cat /etc/modules # /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line. Lines beginning with "#" are ignored. nf_conntrack

Alwin, I have setup the value in the sysctl.conf and rebooted the host, but the standard value exists, is it not possible to override the setting? Proxmox does not have a setting that prevent the change? See here: first i run systemct -p net.netfilter.nf_conntrack_tcp_timeout_established =...

Well it's not working so it must be another setting in sysctl.conf that need to be adjusted. maybe this one net.netfilter.nf_conntrack_tcp_timeout_established = nf_conntrack_tcp_timeout_established This node only keeps track of the...

Ok thank you, I guess this is the one you are talking about ? net.netfilter.nf_conntrack_generic_timeout = 600

I found a way to do it, and that is to restart pve-firewall to get it to take action, is there a API command for this available ?

Let me clarify, i know this is iptables rules added to the hosts, and that not have nothing to do with the actual firewall on the virtual machine itself. Somehow i get it working now, but you need to restart the virtual machine each time you remove a IP to the ipset list. (and i tried to remove...

IPset is enable and firewall is activated on the virtual machine. See attached files: root@pve1:~# pve-firewall status Status: enabled/running And i can ensure the firewall is working, when i set input to DROP it totally block all incoming traffic. So there must be something more with...

Hi Alwin, Thank you for your quick reply. I mean both for mac spoofing and IP spoofing. Ok so you have to edit the file /etc/pve/firewall/<VMID>.fw for each of the virtual machine. Is this also included KVM/LXC? When i try to add it like this: [IPSET ipfilter-net0] # only allow specified...
