I have a three node cluster. I am struggling to understand SDN. (This is the right way to go, right?) I want to create a private network contained within my cluster. "Simple" is an isolated bridge that does not allow VMs on different nodes to talk to each other. Given my simple needs, is VLAN...

A bit of both. I'm exploring what SDN is good for. While I never said this, I am doing this in a corporate environment. I have three Proxmox 8.2 nodes. I am using two NICs. One NIC goes to our general network. The other NIC on all three nodes is plugged into a standalone switch. The latter...

You are right, I was using "simple". I deleted the entries in Proxmox associated with my simple zone. I have tried "VLAN Zones" but DHCP is no longer working. Now what?

I have a three-node Proxmox cluster, all running 8.2.7. I would like to create two Linux VMs on different nodes in the same cluster and have them be able to talk to each other. I assume using the SDN functionality is the proper way to do this. I have created a zone with an ID of sdn100 I have...

Suppose I create a VM on CEPH storage (RAW) and I snapshot the VM, where is the snapshot stored? Is it even a separate file?

Depending on the type of CPU load. Very simple tests like prime number generation show no difference.

The default setting of the host type is a matter of great discussion. See https://bugzilla.proxmox.com/show_bug.cgi?id=1564 Using the default CPU type will dumb down the emulated CPU. In Proxmox VE 8.2.4 the default is "x86-64-v2-AES". This is equivalent to Westmere or Opteron_G4 CPUs. The...

I respectfully disagree. The "default" host type removes many of the optimizations modern CPUs have. Just look at that article's results comparing Proxmox (default) vs Proxmox Opi (host). Huge increases when using the host settings.

Storage Review has updated their post, adding "Optimized Proxmox": https://www.storagereview.com/review/hypervisor-showdown-performance-of-leading-virtualization-solutions

Are there are configuration options or performance tuning available for CEPH?

Here is the solution.. Update PBS Go to Datastore -> Your PBS storage. Click on Options. Set "Notification Method" to "Notification System" Should work for you now.

BTW: I set the From address in the Notification Target. It seems like the Verify job does not use it.

PBS 3.2-2 I am trying to set up email notifications. When I go to Notification Targets, and hit Test, I get the test email with a From address like myaddress@company.com. I then go to my PBS storage and set up my verify job and run it, I receive a warning email from the mail server saying it...

PBS 3.2-2 I am trying to setup PBS to send notification emails to an SMTP server that does not need authentication to local email addresses. Here is what I set up: First thing I noticed is that even though I made a change, the OK button is greyed out. If I add a comment, the OK button is...

As we discovered with the Storage Review of Hypervisors, the default host type incurs a performance penalty. I would like to suggest a better "default" setting. With a single node, any setting other than "host" is pointless. In a cluster of multiple nodes all with the same CPU type, any...

So they compared the "default" settings which are generally geared towards max compatibility not towards what a sane SysAdmin would use. Unfortunate.

In the documentation (https://pve.proxmox.com/pve-docs/chapter-notifications.html#notification_matchers_field) for type, only vzdump is listed. Is there a list somewhere of these types? Or is that it? Thanks.

Thanks. Opened an enhancement request number 5509.

What do the first and second columns with numbers represent? Should they not be labeled? Just wondered.

Yes, you are correct. The path should have been "/mnt/datastore/datastore_name/vm" Since the content of these folders are quite small and the data is dedupped, what process cleans up blocks no longer used?
