I tested the following: - Install cloudbase-init beta in a Windows 2022 Server VM - Shutdown VM - Attach cloudinit drive, set network config - Start VM - After some time, Windows renames itself to the VM name and reboots - Network config gets applied after some time (see below) One thing I noticed: Without modifying the the standard in-guest cloudbase-init configuration, it takes ~2min until cloudbase-init does anything (in particular apply the network config). Apparently cloudbase-init tries to find an HTTP server with the cloudinit data first, and only looks into the configdrive after a timeout. To avoid that, Mira suggested to change `metadata_services` [1] in the cloudbase-init config to `cloudbaseinit.metadata.services.configdrive.ConfigDriveService`. Indeed, with this setting the network config gets applied immediately on boot. It may be nice to add this to the documentation. I'm not sure if the default behavior of changing the hostname to match the VM name is something that Windows admins expect? Should the docs mention more prominently how to disable this? > There seems to be an issue with the network adapter. Whenever the guest > is shutdown and started again it finds a new network adapter.

I couldn't reproduce this issue so far (using a virtio NIC). _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
