Problem network card

[joce]

Hello,

proxmox: 7.2.11
vm:windows11
2 network cards: 1 for wan, 1 for lan

everything worked perfectly until the update of windows 11 in version 22h2. (on 22h1 = ok)

the wan network card works perfectly (physical hardware realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controlle)

the lan network card is visible on windows but does not ping anything (physical hardware: Intel Corporation 82574L Gigabit Network Connection)

my problem therefore concerns this card (lan)

in shell proxmox, the pings pass perfectly, in the vm windows nothing.
I blame the fact that windows was installed on an i440fx hardware profile and not q35. the equipment was purchased new two years ago so recent.

as soon as I change the hardware profile to q35 impossible to start the vm (windows blue screen cannot start):

()
trying to acquire lock...
TASK ERROR: can't lock file '/var/lock/qemu-server/lock-100.conf' - got timeout

Do any of you have an idea please?

As far as I know, Windows cannot handle the switch from machine type i440fx to machine type q35: it won't start and become unresponsive. I have little experience with Windows but I think you need to reinstall Windows when switching machine type. I have no idea why the Windows 11 updates breaks your network.

merci @leesteken je comprends pourquoi je ne peux pas le faire
je vais retélécharger windows
si en attendant que l'un d'entre vous ait une idée concernant ma carte réseau, je suis intéressé, cela m'évitera d'avoir à tout refaire.
