Hello. Out of curiosity. When we do a backup of our VMs with Proxmox Backup Server, we use the snapshot method. It works perfectly. But when we create a snapshot over the web interface for a certain VM, the VM get's stuck for about 20 minutes and the snapshot creation fails with an timeout. And...

Hello, do not know if the answer to my question is obvious..... If I make on our 4 hosts cluster a backup job of all VMs, are the VMs backed up sequentially? Or for example is a backup started on every host, so there wil be 4 backups running in parallel? Latter would not be a good thing in our...

Hello, I have a doubt. Do I need to reboot the PVE hosts on every update, or only when there is a new kernel? For example now I have the following Updates waiting: libproxmox-backup-qemu0/stable 1.0.3-1 amd64 [upgradable from: 1.0.2-1] libpve-storage-perl/stable 6.3-8 all [upgradable from...

Hello, we are evaluating to install a Proxmox Server and while reading the documentation, some question have arisen: 1. is the datastore encrypted or do I have to use client-side encryption? We do not need client-side-encryption, but would be nice if the datastore itself is encrypted...

Hi, we have added a new server to our cluster. When we try to migrate a VM from the old (Intel Xeon 5120) to the new server (Xeon 6240) we get the following error: 020-11-16 10:08:32 starting migration of VM 175 to node 'pve8' (10.10.2.94) 2020-11-16 10:08:33 starting VM 175 on remote node...

Hello, what is the maximum size of a single QCow2 Image for a KVM VM? Have a client who wants a VM with 10 TB diskspace. Can/should I assign a single QCow2 file with 10 TB or assemble with LVM p.e. 5 x 2 TB Images? Thanks and greetings, Thomas

Hello, installing Proxmox on SATA-DOMs is a valid option? I saw older threads where it was not recommended. I thought to use two SATA-DOMs in mirrored configuration, which are 64 GB in size and rated at 1 DWPD, shouldn't they be reliable enough only for the OS? Regards, Thomas

Hello, Friday evening one of four hosts in our PVE cluster got out of memory. It killed the qemu process of one of our VMs, fortunately no apparent damage, restared without problem (apart the obligatory disk check). The killed VM is a CentOS 6 fully patched, 64bit. At the moment the host is...

Hello, we'd like to add two servers to our existing Promox 6.0 Cluster. Can we use the 6.1 iso's or better first install 6.0 to join the cluster and upgrade afterwards to 6.1? Thanks, Thomas

Hello all, I had a very strange and scary problem with one of our VMs when resizing a disk. The discs of the VM where imported through 'qm importdisk....' from an XenServer xva file. I cloned the VM to do a test and tried to resize on the clone. VM had 3 disks (scsi0 -> 2), where I tried to...

Hello, I have this message from kernel when I mount manually a NFS share: [158568.381905] FS-Cache: Duplicate cookie detected [158568.381943] FS-Cache: O-cookie c=00000000d6bc3b33 [p=000000007206c149 fl=222 nc=0 na=1] [158568.383018] FS-Cache: O-cookie d=000000004b7a1f04 n=0000000027a0466e...

Hello all, we have a big problem importing Windows 2016/2019 VMs from XenServer. We get the bluescreen with the error above, Safe Mode gives the same error. At the moment using Proxmox with the non-enterprise repository, fully updated. Tested on running a Xeon Gold 5120 and an old Operton...

Hello, we have installed a Open-E cluster and originally intended to share the disks via iSCSI. But LVM on top of iSCSI does not support snapshots, which is very bad for us. Looking at https://pve.proxmox.com/wiki/Storage would have prevented the surprise, I know. :-) lvm-thin does not work...

Hello all, we will buy new hardware for our migration from XenServer to Proxmox and need some advice/recommendation. First are AMD Epyc CPUs an alternative to Intel for Proxmox? Are there compatibility issues? Will be an two AMD Epyc 7351, 2.40 Ghz 16 Core or two Intel Gold 2,20 Ghz 14 Core...

Hello all, I'm testing a Proxmox installation with local and iSCSI Storage. I wanted to test how a disk move behaves when the VM is busy working on the disks. So I launched a fio in the VM, with a sequential write profile. And while this was running I tried to move the disk from local ZFS to...

Hello all, I created a new user with access rights 'Administrator'. But he can not display the '>_ Shell' screen of the Proxmox host. It gives the error in the attached screenshot. Is there a way to resolve this? Thanks, Thomas

Hallo all, we bought today a licence key for our Proxmox VE 5.1 Server. I added the key in the subscription menu, removed the 'No-Subscribtion-Repo' from the /etc/apt/sources.list and reactivated the enterprise repo which I had previously commented out...
