hotplug

I have two Windows Server 2016 virtual machines running on Proxmox 8.2.7, one of which has a USB disk drive attached to it to make quick file backups. I swap the drive every few weeks and has been without issues. However, on the last swap, I had an issue that caused both VMs to suddenly have IO...

I'm new to Proxmox VE after migrating from VMware ESXi, I'm running PVE 8.2.7. TL;DR: How does Proxmox and the virtual machine behave if I unplug a USB disk drive without unmounting properly on Windows Server despite being set with Quick removal policy? What are the chances of the VM or node...

Hi Everyone, I'd like to first state I have reviewed this Link. I have tried to install these 2 modules below: # modprobe acpiphp # modprobe pci_hotplug I receive a fatal error when I try to install the modules. I believe these are now built into the latest Proxmox kernel. Here are the...

Hi Devs, Using memory hotplug according to the proxmox wiki I succesfully increased and decreased the memory size of a Debian/Ubuntu guest. However when booting a virtual machine with memory hot-plug enabled and more than 21GB memory the guest OS can kernel panic with the following error...

Hey everyone, I'm having an issue with hotplugging CPUs in Proxmox. Here's what's happening: Set a limit of 6 vCPUs. Launched a Windows VM with 2 vCPUs. Enabled NUMA and hotplug options in the VM settings. When I try to increase the number of vCPUs using the edit option in the hardware...

I've read the NUMA wiki here: https://pve.proxmox.com/wiki/NUMA and the admin guide regarding NUMA here: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#qm_virtual_machines_settings however I still have some questions. * Is NUMA only useful if your PVE *host* has more than 1 physical...

Hello Proxmox Community, I'm using Proxmox on my home server. I have several USB Devices (DVB-S Receiver, 3D Printer + Webcam) that I want to connect to my Server and use from Docker Containers (Running minisatip or octoprint). The USB Devices are turned off most of the time and are only turned...

Just upgraded my testlab to latest pve no-sub. I did not install updates for 3-6 months, so no idea which one broke it. VM boots and crashes with kernel trace, as soon as I disable memory hotplug it boots just fine. Using debian cloud generic image. [ 4.912084] Hardware name: QEMU Standard...

Hi When I want to hotplug vCPU and increase it, I will get below error : Parameter verification failed. (400) vcpus: hotplug problem - you can't add more vcpus than maxcpus while the "CPU limit" is unlimited . I'm using proxmox VE 7.2

Hello, This had been asked several times however after extensive search there is still no real answer that would make sense or a formula that I was able to follow to assign memory - sometime it work and sometimes doesn't (guessing!) up to 48GB works fine after adding this workaround "options...

Hi, After a full week of test I publish the script I made to convert my local proxmox PC to a real PC. I can plug an USB flash drive to the proxmox host and the key popup on my current KVM windows/Linux/MacOs. https://www.npmjs.com/package/proxmox-usb-hotplug See the "use as a service" for a...

initially my experience with Proxmox 6 was rather disturbing, eventually i resolved what caused these issues and proxmox works well for me now. Recently (yeah) though i took on myself to install FreeNAS and OPNSense which are FreeBSD based and both behave "weird". The vm config i use can be...

I just configured hotplug for CPUs and RAM on one of my VMs and have been testing it. Hotplug for the CPU and RAM work but unplug fails every time with the error: Parameter verification failed. (400) vcpus: hotplug problem - 400 Parameter verification failed. vcpus: error unplugging cpu4...

Hi, We have two PVE 6.0-x clusters with 3 nodes each. The nodes are Dell R640 servers. Both clusters are fairly new and we are in the process of installing out first VM's. The VM's are running SLES 15 SP1. As we would like to have the option of adding vCPU/RAM, we activated hotplugging on the...

Hi there, we're using Proxmox VE since some years right now. Lately we need to disable hotplug network card functionality from Windows Guests VM because users, sometimes click in the wrong place and they do "safely remove hardware for network card"!!!! We're using the latest virtio-win driver...

Hi, I have a personal Proxmox environment I use for testing, for it I use the community repo which is running the latest version of proxmox VE (5.2-2). Full package version list: proxmox-ve: 5.2-2 (running kernel: 4.15.17-1-pve) pve-manager: 5.2-1 (running version: 5.2-1/0fcd7879)...

Hi all, I'm using PVE 5.1-36 and i get some issues with usb hotpluging. Is there a way to hotplug an USB key to a VM without shutdown/reboot? I know that i had to add some config files on the node to enable hotplug RAM and hotplug CPU. Is this the same for usb hotplug? I tried different ways...

We're having problems with all newer pve-qemu-kvm versions, every version newer than 2.5.19 is causing a unpredictable crash of our VM's. I've setup some tests and reproduce details, can you please check your configuration, with this test you can crash your VM in a few minutes. My test VM...

Hello, I'm experimenting CPU and RAM hot plugging with KVM. I can add or remove RAM from a running VM. It works great! I have read that reducing RAM is not supposed to work, but all worked at the first try. Maybe I read outdated articles? (tested with proxmox 4.3, ubuntu 16.04 guest) I can...
