Hello everyone. I have the following problem. The network part in the cluster works on Linux Bridge using VLAN. The problem is that one virtual machine receives traffic that is not intended for it. It feels like the Bridge works like a regular network hub, not a network switch, and sends all...

Hi all. I have the following question. There are 2 PBS One with a large amount of storage where backups are made from different Proxmox VE nodes, and the second with a small amount of storage. Is it possible to pick up certain virtual machine backups in the amount of 3 from PBS with large...

I would like to try using ssd as rbd persistent cache CEPH device. But it didn't work for me because I can't specify the DAX mount option. Is this functionality missing in PVE or am I doing something wrong?

Greetings. Can I completely disable SDN in a Proxmox VE 8 cluster. I don't plan to use it. If there is no way to remove it, how can I hide the SDN settings from the interface?

I have been configuring and testing ceph. When OSDs were first added, the performance values of the added osds were automatically added to the configuration database. However, at some point it stopped working. Should it work? Maybe some update came that turned off this functionality? Running...

A situation has arisen. Set to MTU 9000 via the web interface. Used by OVS. After restarting the server, the MTU on some interfaces drops to 1500 - bond and ovs-system. How can I fix this? proxmox-ve: 7.4-1 (running kernel: 5.15.107-2-pve) pve-manager: 7.4-3 (running version: 7.4-3/9002ab8a)...

For several weeks now, I've been struggling to improve the performance of ceph on 3 nodes. Each node has 4 disks of 6 TB. + one NVME 1 TB where Rocksdb / Wal are taken out. I can't seem to get ceph to run fast enough. Below are my config files and test results: pveversion -v proxmox-ve: 7.4-1...

Hi all. I have the following configuration. 3 nodes. Each node has 4 6TB disks and 1 1TB nvme disk. A total of 5 OSDs per node. I decided to launch the ceph caching functionality by following these steps: Will this have any effect? Or are all these steps useless? Possibly a misconfiguration?

Colleagues, I had a problem with migrating a virtual machine from one cluster node to another when using lvmthin. The essence of the problem lies in the fact that the process seems to be going on, but the result is 0% () 2023-05-16 22:12:49 starting migration of VM 137 to node 'node02'...

I'm currently using a OviOS Linux as my main NFS storage and PBS as virtual machine. I'd like to continue to use network storage as my backup target. How would add my NFS share to the Proxmox Backup Server as storage?

Hello everyone. How hide the cluster nodes for the user if virtual machines are not running on them. They are simply displayed if the user is logged in.

Hello everyone, I'm trying to use ovios linux for my tests as a network storage. There was a connection problem. Generated a key and sent it to san. I am trying to add a disk to the virtual machine and I get the error: No configuration found. Install iet on 192.168.1.169 at...

I ask for help in understanding how to correctly create and use the API Token. I first create a user and then create a token for that user. A token ID and secret is generated for me. I'm interested in what UUID is in USER @ REALM format! TOKENID = UUID

Hello everyone. Faced the following problem. Configured NAT and DHCP for virtual machines on Proxmox. After each reboot, when receiving an IP address via DHCP, the virtual machine with Windows constantly finds a new network. Although the network parameters are correct. What could be the reason...

Hello. I configured Nginx according to this instruction. Everything works great. It has become much more convenient. But the following question arose: ngnix is blocking ports 80 and 443 to obtain letsencrypt certificates. In order to regenerate the certificates, I had to manually stop nginx, get...

As far as I understand, when using multiprocessor boards based on Proxmox, you need to use NUMA in virtual machines. Are there any recommendations for enabling NUMA in virtual machines? Perhaps depending on a certain amount of RAM and the number of cores? In what types of machines is it better...

Hello. tell me, can I somehow deploy a new virtual machine from the created snapshot? Is there any way to do this? For example, a user deleted a file inside a virtual machine. It is expensive to deploy backup and sometimes it is outdated. But there is a daily snapshot created by cron. In order...

Can you please tell me how much the bandwidth drops when switching from the classic network design in Proxmox to openvswitch?

I made a backup of the virtual machine before replacing the hard drives. Copied it to USB. There were no problems. The size of the copied file was the same as the size of the created one. The virtual machine was turned off at the time of backup. When trying to restore a machine from a backup, I...

Hello. The following question arose. For example, I have a snapshot of the system every day at 21.00 from Monday to Friday. On Saturday at 00.30, backup starts by creating a snapshot. What exactly will be included in the backup file? The state of the VM before the last snapshot was taken, namely...
