Thanks for the pointer Fabian. This is exactly it.

there was a change in how Qemu sets up PCI slots. we record the version with
which the VM was first created exactly to avoid this change during the lifetime
of the VM:

Hi,
I'm experiencing a rather strange behavior with VM creation on a 7.7
proxmox cluster.
I do have quite old (migrated from older proxmox versions) VMs as well
as new VMs (created after the 7.2 version).
Config file:
$ cat /etc/pve/qemu-server/889.conf
boot: order=virtio0;ide2;net0
cores: 1
cpu: host
ide2: none,media=cdrom
machine: q35
memory: 2048
meta: creation-qemu=7.0.0,ctime=1687340877
name: vs-lcaron-testalacon
net0: virtio=C2:B9:B3:FE:6C:B0,bridge=vmbr2000
numa: 1
ostype: l26
scsihw: virtio-scsi-pci
smbios1: uuid=ef269cd3-e7a6-442e-87ad-30b68741003b
sockets: 1
virtio0: VMs_NFS:889/vm-889-disk-0.qcow2,discard=on,size=64G
vmgenid: ac09af11-7012-41eb-99e3-ca1162afc2bd
Using this config, VM installs fine.
Interface name is enp6s18
If I do remove the line 'meta: ...' from the config file, and restart
the VM's interface is now ens18.
Please note, when using 'meta: ...' lspci | grrp Ethernet is:
06:12.0 Ethernet controller: Red Hat, Inc. Virtio network device
When not using 'meta: ...' lspci is exactly the same.
What is changing behind the scenes when using 'meta: ' in the config file ?
I'm trying to have a consistent naming across VMs, wether the VMs were
instanciated on an old or a new proxmox version.
Thanks
