online migration with local-disks break VM hotplug nic addition

[auranext]

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?

 

[auranext]

no ACL and no specialties in VM network config
Do you now how to debug hotplug tasks ?

This depends on the Guest OS.
