If I set the MTU to 1500 on the network interface over vmbr2, the migration still fails, and the logs show that it attempts to set the MTU to 9000 The bug report you're referencing is from 2017 and has also been closed. Are you going to investigate anything else, or is the solution...

I've found the following: A machine with its network on vmbr2 fails to migrate, but if I use a bridge created with SDN (without touching the MTU), the migration from Proxmox 8 to Proxmox 9 completes without issues. A machine with its network on vmbr2 migrates correctly between nodes with...

Hello, I'll explain my situation a bit better: We have a 9-node cluster, and until yesterday, VM migrations were working normally. I updated one node to Proxmox 9, and any VM I try to migrate to it fails with an error. Yesterday, I tried changing the machine type to q35, and it worked, but...

Hi, i have the same error Migration of a VM with Q35 works fine, but a VM with Default (i440fx) ends with errors. () 2025-09-01 15:25:31 starting migration of VM 146245 to node 'xxxx' (xxxx) 2025-09-01 15:25:31 starting VM 146245 on remote node 'xxxxx' 2025-09-01 15:25:33 start remote tunnel...

Hi, Finally, it only happened with two nodes in the cluster, any machine that was migrated froze, so we made the decision to turn off, move, and turn on. Now with the entire cluster in version 8 there is no problem. BR

Hello, we have a cluster with several servers running version 7.4, and we have already updated a couple of them to version 8. When we move machines from a server with version 7.4 to one with version 8.0, the machines experience kernel panic. This happens with different operating systems and...

Hi, Try with qemu-system-x86_64 -enable-kvm -smp 4 -m 4096 -bios /usr/share/ovmf/OVMF.fd -boot d -cdrom ./proxmox-ve_7.1-2.iso -drive file=/dev/sda,format=raw,media=disk -drive file=/dev/sdb,format=raw,media=disk -vnc 127.0.0.1:1 BR

I think that all problems are caused by qemu agent, for example: INFO: Starting Backup of VM 801036 (qemu) INFO: Backup started at 2020-10-15 08:32:55 INFO: status = running INFO: VM Name: xxxxx INFO: include disk 'virtio0' 'zfs_ssd:vm-801036-disk-0' 50380M INFO: backup mode: snapshot INFO...

Hi, cmdline of my vm is: BOOT_IMAGE=/boot/vmlinuz-5.4.0-1024-kvm root=PARTUUID=948a082e-cfd1-43af-bc7b-3e0b9b20370e ro memhp_default_state=online console=tty1 console=ttyS0 panic=-1 But not works

I'm trying to assign 4GB of ram to a virtual machine, but after I enabled hotplug for memory and cpu, the ram that the vm sees is not 991 (actually 1GB). Before enabling the hotplug, it worked as as expected. The problem only appears with ubuntu 20.04 and the cmline is: ~$ cat /proc/cmdline...
