From which version do you upgrade. 4.2.4 works fine for me.

In the past i had a similar issue while upgrade from x.x.x to 4.2.3 with double network and disks.

I run RUN->ONCE OK (Error message ignore) OK, then run normal with RUN that fixes the issue.

I updated the engine, and one of my nodes to 4.2.5.  I'm attempting to re-start the VMs that were pinned to it, and migrate another VM to it so that I can update my other node. 

When I try to start the VMs that were pinned to the host, I get:

VM Tuning3 is down with error. Exit message: XML error: Multiple 'scsi' controllers with index '0'. 

To fix this I tried to detach the disk and re-attach it, no luck. 

 When I try to migrate a running VM to this host, I get:

Host Letty has network interface which exceeded the defined threshold [95%] (bond0: transmit rate[0%], receive rate [97%])

The host I'm migrating FROM gets a similar error, and the VM does not migrate. I tried the different migration policies without any luck.  

I did successfully migrate the Hosted Engine to the new host, no errors. 

Thanks for any advice!
