migration

Hi all, is it correct that by default Proxmox 9 in a 3 node cluster configuration with CEPH for VM migration use VMBR0 network? Current node network config does use a separate network for CEPH Cluster (10.10.10.x/24), CEPH Public (10.10.20.x/24), COROSYNC (172.16.1.x/24) and VMBR0...

My organisation is about to migrate circa 100 VMs, from a bunch of libvirt machines to a brand new PVE cluster. We found a few pointers about the migration process, but it requires a lot of manual intervention. Is there a way of automatize the process as much as possible ?

I am trying to migrate a physical windows test server to Proxmox. These are the steps so far: 1. used Disk2vhd and created a vhd file on a USB Drive. 2. Connected the USB to a Ubuntu machine and ran qemu-img convert -p -f vpc -O qcow2 WIN-4GSGQMJ1U8A.VHD WIN-4GSGQMJ1U8A.qcow2 So, I now...

Hi all, I am on Proxmox 9.0.10, with 2 servers in my cluster. I have a relatively large VM disk, which fails on live migration every time. The initiating HV is LVM and the destination is ZFS. I have attached the full migration log, but the error is mainly channel 4: open failed: connect...

[GUIDE] High-Speed, Low-Downtime ESXi to Proxmox Migration via NFS Hello everyone, I wanted to share a migration method I've been using to move VMs from ESXi to Proxmox. This process avoids the common performance bottlenecks of the built-in importer and the storage/downtime requirements of...

Hi. I've recently added an LVM thick storage to my PVE cluster which is a LUN shared between 4 of 5 nodes and everything works just fine except VM migration. I migrated VM from the 5th node which only has local storage to different node and shared LVM storage. Now I can't migrate it back. When...

Hi ! I have a 3 node cluster on Proxmox and one of the Hosts has some issues I couldn't identify till now. To have my VM save I wanted to put it onto a dedicated (external) NFS where the VM is hosted so that I can easily move the VM between by cluster. If I do the migration between the 2 "good"...

Is it possible to define a migration type per VM so that it's always applied to that VM? I have some VM's that I always need to be offline migrated for a few reasons (one is for example a connected PCI device, which is available on all nodes). For this VM's I would like to specify that, if they...

Hello all! This is the first time I've used the migrate feature. I have two nodes in a cluster, and I was looking to move all containers from Node 1 to Node 2. I used the bulk migration option, and it migrated more than half of the containers that I have. However, for some reason, there are a...

Hello, I am having an issue with the live migration option in Proxmox. I am getting ready to migrate off of ESXi 8 and move over to Proxmox. We are currently in the testing phase and have a few test VMs in the ESXi environment and a lab PVE cluster setup to emulate what we want our production...

Hi everyone, we’re currently facing an issue after migrating a legacy SCO OpenServer 6 virtual machine from VMware to Proxmox. Here's what we’ve done so far: Successfully converted the original .vmdk file to .qcow2 using qemu-img. Created a new VM in Proxmox and attached the converted .qcow2...

We are in the process of migrating from VMware to ProxMox. We have a Primary site and a Secondary site in case the 1st one fail. To ensure proper design, we are questioning how we should setup the storage of the SANs (iSCSI) for proper failover redundancy. We did a lot of reading, but no...

Hi Forum, I am new to HA and have a running setup for two months now. From the experiences that I have gathered it looks like live-migration using a HA group fails on almost all VMs and CTs with a database (sadly almost everything I have). These were the result of changing the HA group...

Hi, I have a ProxMox node running 7.4-20 on bare metal which has a container whose Root Disk image is on a local Directory type volume. I recently bought a new server and installed ProxMox 8.4.1 on that (also on bare metal) and would like to migrate my container to that including putting the...

Good Morning/Evening, I didn't think I'd ever have to but I have several VMs running on one physical disk that I want to move to another datastore on another disk. I can move the storage one at a time through the web ui but I was wondering if anyone knows of a faster method? This will be...

Hi, I’m experiencing very slow disk migration in my Proxmox cluster when moving a VM disk from FlashME5 (iSCSI multipath + LVM) to CephStorage (RBD). Migration from Ceph → FlashME5 is fast (~500–700 MB/s), but in reverse (FlashME5 → Ceph) I only get ~200 MB/s or less. Environment: Proxmox 8.x...

Hello, I am currently having a problem with mail notifications, I have 3 servers: pve-server-01, pve-server-02 and pve-server-03(This last one is only used as a quorum device). A few months ago I configured the notifications using an SMTP server(Gmail) in Datacenter->Notifications and until...

Hello I've been using Hyper-V for years, but since Microsoft no longer offers free Hyper-V since Windows Server 2022 and I couldn't figure out how to configure VLANs on the single active host NIC, AND Windows Server 2019 didn't have drivers for the second NIC, I finally decided to migrate to...
