Before migration, the virtual machine network is normal and can be pinged。

Migrating virtual machines from one exsi host to another

The virtual machines network will be down for a while，About a few minutes, up to 20 minutes, and then it’s done automatically

or login by vcenter console，Ping the gateway from inside the virtual machine to the outside,or resrat network service,it will be normal.

I suspect it is the ARP problem(the function of MAC address triggers ARP update) of Huawei switch.

Have you encountered it? thanks
