    we currently use 2nodes cluster in proxmox 5.4 version with ZFS local sortage
    VMs are replicated with PVE native replication jobs.

    We have 2 migrations cases
    first one using offline migration
    VM is shutdown after a fresh replication task and started on remote node

    second one using online migration
    VM is online migrated with online sync local-disks + RAM state
    for this migration case we use this command
    /usr/sbin/qm migrate 100 CLUSTER1-NODE2 --online --with-local-disks --targetstorage zfsraid10

    the whole operation is going well.
    However after migration the hotplug network card addition is broken
    everything goes well in the WEBui but the VM does not receive the new device
    a reboot of the vm restore the hotplug functionality
    naturally this problem does not occur with the offline migration method

    someone have similar experience ?
    is there a known solution ?

    Hi,

    no there are no problems known.
    Do you have any specialties in your Network like ACL?

    This depends on the Guest OS.
