migration

I have a Proxmox with LVM thin (datathinpool), I want to migrate all the container to a new server using ZFS (vmdata) But when I try to do it I got: # pct migrate 120 lokol --restart --target-storage vmdata 2025-01-16 13:53:22 shutdown CT 120 2025-01-16 13:53:26 use dedicated network address...

Is it safe to migrate a Windows server VM from one cluster to another? I am not sure if any licensing problems can occur.

Hi, Today we tried rebooting our nodes one per one. We used the ha-manager crm-command node-maintenance enable like we did several times before. However, this time it seemed to migrate too many vms to the same node which caused this node to crash due to it's memory usage. I just read some...

I've been giving "remote migration" a try for the first time today, moving machines live from a single host running ZFS to a new cluster running CePH. It worked tremendously well—without issues and on the first try—for all VM's but one, which always fails with the following errors. I tried...

Hello, i am planning to move my one node Proxmox server with VMs to a new 3 node Cluster with Ceph Pool. Now are my questions: 1. Whats the best way to move the VMs to the according Ceph Pools on the Cluster, with minimal downtime. 2. Is there a way for testing to just copy a VM from the...

Specs: I have 2x SFP+ ports and 2x 2.5Gb on my Proxmox servers. What is the best practices to use it? Situation now: I now have the 2x SFP+ aggregated and several VLAN's connect via this to the network and I have 1x 2.5Gb management port with a dedicated ip address. The other 2.5Gb port is not...

Hello, I have a very strange problem. I have two PVE 8.3.0 nodes with AMD Ryzen CPU's, 64 GB RAM, 1 TB NVMe with ZFS and 2x 2,5 GBit NIC's on each node. All VM's replicate from node1 to node2 every 15 minutes. Node1 is the primary node, node2 was just added. When I try to live migrate a VM...

Hi there friends! I'm attempting to move off ESXi on a server (surprise, surprise), and one of my VMs is being particularly petulant. It's a Debian 12 VM, running a pretty standard LAMP stack, set up to boot with UEFI. I tried moving it with the ESXi Import function, and when I did, it sends...

We are testing the live migration on 8.3.0 between both clusters and we're running into one issue we can't seem to find a good resolution to. Whenever we migrate a machine it can't pull networking because for some reason the arp table on the source is still holding on to the mac address. We've...

Hi all, I recently stumbled when trying to migrate a VM from a node with an encrypted ZFS dataset to a node without encryption: ``` cannot send nvmepool/vm-310-disk-0@__migration__: encrypted dataset nvmepool/vm-310-disk-0 may not be sent with properties without the raw flag ``` It's not a...

I tested several ways to import a Windows Server 2019 VM from ESXi (version 7), here are the configs I was able to test: - processor: host / Disk : prepared for VirtIO / BIOS : SeaBIOS (my machine has no UEFI on Vmware )/ Machine : by default(i440fx) / SCSI controller : VirtIO =...

Hi, I have a grip of ovf exports from a couple ESXi servers I need to import into Proxmox, and I was wondering if people have recommendations for flags to use during the import process I added devices manually on the first VM, which will be a pain if I have to do the next 10-12 of them that...

Hi all, I'm experiencing an issue where something keeps modifying my /etc/pve/datacenter.cfg file, specifically deleting the migration: entry I add. I add this line: migration: type=insecure,network=127.67.0.0/27 The configuration works for a while, but after some time, the entry disappears (no...

I'm devops intern at startup company, I'm new to proxmox things they hosted their production application in proxmox (spring boot and mysql) both run in different vm my task is to migrate that application to aws what are steps to do this migration?

Hello, I have a few Windows 10 machines with retail Licenses keys running on a Hyper-V Server. Consulting several migration guides, it appears that only the vhdx file is converted and transferred, which (I believe) means the hardware ID of the hyper-V vm is left behind - meaning the windows...

Liebe Community, ich habe generell eine Frage zum Migrationsprozess auf Proxmox. Was genau passiert technisch gesehen bei Proxmox, wenn eine VM von einem Knoten auf den anderen migriert wird? Was schleift er dann generell an Daten auf den anderen Knoten mit rüber? Ich habe dazu recherchiert...

If you encounter the below error while trying to migrate a VM from with CLI or with GUI. Do check if you have an unreferenced USB device added to the VM. This is something I encountered and solved while fiddling around. So letting you all know. BR, MB

Hi Everyone, I have learned to migrate just fine within clusters and moving VM's via HA but this question is in regards to migration to other Proxmox hosts without a cluster. A straight P2P method. I suggested using the backup option to a Proxmox Backup server then restoring it but that just...

Hallo Zusammen, Im Proxmox Cluster ist eingestellt dass VMs über HA migrieren sollen, wenn ein Knoten down ist. Dies hat allerdings bei einer Node mit vielen VMs zu einem unerwarteten Verhalten geführt. Die Migration ging sehr lange, und bei ca. 50-75% migrierten VMs ist der Knoten einfach...
