I'm having the same problem on just one VM.

I'm having the same problem on just one VM, none of the others.

That would be good, except I can't use Docker, Podman or Kubernetes for my usual work.

Don't know if people have considered the use of Proxmox VE as a development environment. Let me explain how I am using it. I am called on to develop installation scripts for Linux VMs. Most of these scripts make changes to the OS or install packages. Here is my methodology: Install the OS...

Seems like the error message could be improved on. Maybe with a suggestion of memory values to pick. The memory size input field has up and down arrows to increase or decrease the memory in 32 byte intervals. Can we make these arrows suggest working values? Is there a chart or graph show the...

I'm now on 8.3.2 and SDN still seems like a technological preview. Any news on improvements?

I am still having this problem on PVE 8.3.2. My max_mem_regions is set to 509 in vhost.conf. What should it be changed to? I need hotplug and 64 GiB of memory. Is setting max_mem_regions the answer? I know 65 GB works, but I have 250+ VMs to create, so that jump from 64 GiB to 65 GiB means an...

Given this response and the fact that SMB shares rattle the hard drives (lots of seeks), I'm going to go with NFS shares for my VMs.

I have always used NFS shares which seems to be the most common sharing protocol but today I decided to compare NFS with SMB shares. All of my use is to host VM QCOW2 files. The storage target is a UGREEN DXP4800 Plus running TrueNAS SCALE. It has a mirrored pair of spinning drives. I created a...

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.
