Sounds like your ISP is filtering outgoing communication on port 25. Many ISPs nowdays do that. This is to prevent compromised computer systems from becoming spam bots. Check your ISP's FAQ page or tech support docs. You are suppose to use 587 now... but even then best of good luck to ya...

There is a wiki page with setting up networking in Proxmox: https://pve.proxmox.com/wiki/Network_Model Configuring networking in Proxmox is done the same way as with most Linux distros. You can make changes to /etc/network/interfaces as needed. Similarly, once you have console access to...

Re: pve-firewall prevents VM starts from web interface (also noVNC hangs) So this is getting just weird. A VM on node's local storage can be started just fine with or without pve-firewall being enabled. A VM on replicated storage (glusterfs) and pve-firewall disabled: I can start VM from web...

Re: pve-firewall prevents VM starts from web interface (also noVNC hangs) Did some more investigating. cluster.fw is now just this: [OPTIONS] enable: 1 Web GUI is being accessed from laptop connected directly to the same switch that nodes are on. Laptop has static IP of 10.10.10.8. Same...

Re: pve-firewall prevents VM starts from web interface (also noVNC hangs) I thought I'd bump the post as I've updated wording. By mistake said "node" when I meant VM in a few spots. Also created a ticket: https://bugzilla.proxmox.com/show_bug.cgi?id=620 Any ideas?

You are welcome. Glad we could sort this out :)

At least in my test environment (PVE v3.3) I can't create a permission with an empty path. So if you didn't create a permission that granted access, how did you expect anything to work? :)

You stated you had no clue what to put into PATH field. What did you put in there to begin with? You can't create a Permission without filling something into the "path" field. What do your Permissions look like now?

I have highlighted the relevant part above. Did you now update the path field of your Permission(s) that grant PVEAdmin role to your chosen users? By that I mean you have to Remove and then Add again the permission with correct path. Just as an example (on Proxmox 3.3 box) via web interface...

If you read that wiki page more closely, you will find the following section: If I remember correctly a path of "/" (without quotes) refers to everything.

Which Role did you give to that user? What is the path for the Permission you've created? Edit: Perhaps PVEVMAdmin or Administrator might be the role(s) you are after. From above wiki page: Administrator: has all privileges PVEAdmin: can do most things, but miss rights to modify system...

Proxmox v3.4 nodes in a cluster. I'm attempting to use pve-firewall to secure access to the nodes. Nodes are on 10.10.10.1 and 10.10.10.2. I'm attempting to manage cluster from another machine on 10.10.2.1. I've enabled the firewall as per https://pve.proxmox.com/wiki/Proxmox_VE_Firewall and...

Do you have the pve-firewall enabled by any chance?

I think you will have to create a KVM VM in Proxmox first matching the original VM specs. Set storage to be ZFS pool01. See where Proxmox will create the new disk image (something like zfs://pool1/path/to/disk/images/<VMID>/). Overwrite this new VM's qcow2 disk image with your ubuntu image.

Is your RAID disk configured and done initializing? Get into BIOS and into device configuration (where you can configure network interfaces and raid controller). Check and ensure that your RAID disk devices are created/configured and marked as "ready" (or "online" can't remember).

While in Datacenter, take a look at Roles tab. There is a list of roles that can be assigned to users (or groups of users). Depending on what you want your users to do, go to Permissions tab and create a user/group permission and grant them a particular Role. Description of Roles...

Just wanted to update this. Maybe it will come in handy for someone else who stumbled into the same problem. After some time debugging and testing I know what happened. I now got the local storage setup and working as I wanted. The way I was going about it is setting up the nodes individually...

I'm not a Proxmox developer but I see no reason why this wouldn't work. Proxmox and glusterfs are two different things. Glusterfs provides an underlying filesystem (which can be replicated, spread over multiple storage partitions, etc) and Proxmox merely makes use of it for storing stuff...

Yes, I would also like to see a way to specify migration (or maintenance) network. This would offload main interface(s) from "maintenance" traffic.

Is the kvm process still running after you get this error? ps -ef | grep kvm Is it possible you may have hit process limits? ulimit -a Just out of curiosity: what kind of hardware and total RAM do you have? Why does your VM need 128GB+ of RAM?
