Hi. On my Proxmox 5.1 system I sometimes find some KVM virtual machines hanged. Last week this happened on two different machines: one Windows 2016 and one FreeBSD 10.3 (pfSense 2.3.4-p1): the Windows 2016 virtual machine was hanged with the CTRL+ALT+CANC screen on the console completely...

I've noticed that ARM based server processors with vast number of cores are starting to appear on the market. (Imagine motherboardboard having four Qualcomm Centriq 2400 CPUs with 48 cores each :) While they might be bit inferior in single thread performance, they might be very well suited for...

Hello everyone, I know that there are a lot of threads covering this topic but I could not find any that solve my issues. I would like to run Proxmox headless and passthrough the iGPU (and the capability of displaying the output on a monitor) to one VM. I also tried to use Intel igvt-g but...

Hello I have been trying to get GPU passthrough working on my GTX 760, and I'm having issues with PVE system crashes. I have followed the steps outlined in the ProxMox Wiki, and sshaikh's Tutorial thread. Everything seems to be performing as expected, but as soon as the VM loads in a GPU driver...

As I create new VM for web site I'm in doubt if I should use kvm64 vs host type of CPU for VM. Choose host should looks like can give me more real cpu power (but I limited by real physical cores number), while kvm64 can be set to as high as 128, and (as I can imagine) will share the same...

Can someone point me to the pros/cons of the various KVM display drivers? I'm finding it hard to find reliable info on this topic. My use case is several Linux guests running X, accessible with RDP. Does the configured display driver even matter for this? Note that I am not trying to...

I'm running PVE 5.0-30 with two KVM machines with Windows 2016 Servers installed. I did everything like computerized William explained in this video https://www.proxmox.com/de/training/video-tutorials/item/install-windows-2016-server-on-proxmox-ve. So I use ZFS and VirtIO for storage (SCSI) and...

Hi, I have to migrate many differents Virtual Machines from ESXi 4.1 and ESXi5.1 to Proxmox PVE 5. I read the wiki's articles for many Windows guests, but now I have a problem with a Centos 7 VM. In this case we got the guest booting right setting the disk as SCSI and the controller as LSI...

Hallo alle zusammen, ich setze auf dem Host Proxmox 5 VE ein. Auf den VMs benutze ich Debian 9 Stretch. Problem: Virtuelle Maschine (VM), die im Subnetz 2a01:4f8:c0:17c2::/64 (ipv6) bzw. 88.198.197.24/29 (ipv4) läuft, klappt das Anpingen und die Namensauflösung mit ipv6-Servern nicht. Das...

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...

Greetings everyone. I'd like to thank the developers of this great server virtualization management solution, really love it. Maybe somebody can help me with my questions. My version of proxmox: 5 beta 1 Virtual machine: Windows 10 x64 My gpu: gtx1060 (passed to vm) Config: cpu: host...

Hi! I have Proxmox VE 3.4-3 with kernel 2.6.32-37-pve. My server runs several OpenVZ containers together with KVM virtual machines. At the moment cat /sys/kernel/mm/ksm/pages_sharing returns 0 and that's fine because my RAM usage is under 80% and KSM_THRES_COEF=20 in /etc/ksmtuned.conf. My...

Hello, i'm working on a P2V of a Cpanel server (centos 7). What is the best FS / Partitioning ? I'm reading that using LVM i can do a Hot Resize but i lose performance ... I think i will need to resize mi virtual hd in the future .. Is it ok ext4 ? Thanks !

This issue has been with us since we upgraded our cluster to Proxmox 4.x, and converted our guests from OpenVZ to KVM. We have single and dual socket Westmere, Sandy Bridge and Ivy Bridge nodes, using ZFS RAID10 HDD or ZFS RAIDZ SSD arrays, and every one of them is affected. Description When...
