    vmbrX einer laufenden VM tauschen - Ideen?

    Wie würdet Ihr es angehen?: Ein laufende(!) VM hat eine Netzwerkkarte (net2), die an eine Brücke "gebunden" ist (z. B. vmbr2). Jetzt hat diese Brücke ein Verbindungsproblem, z. B. geht ping 1.1.1.1 an ihr nicht mehr. Dann soll in der laufenden VM net2 nicht mehr an vmbr2, sondern an vmbr1...

    Bond 2 10GbE for 20GbE Windows Server?

    Hey all, Is it possible to bond 2 10GbE ports in Proxmox using LACP and use that bond in a vmbr to add to my Windows Server VM? When I try this the adapter in Windows still says 10GbE instead of 20GbE. I know I need to also aggregate the ports on my switch and have done so. Thanks.
