I have an environment for testing with two Windows server 2012 servers in a cluster. I am running all network traffic through a virtual switch connected to a NIC team with two 10GbE adapters. I have the following virtual network adapters presented to the hosts and connected to the virtual switch:
*Host management
*Cluster traffic
*Live migration
*iSCSI1
*iSCSI2
If I from Virtual Machine Manager 2012 SP1 right-click on one of the hosts and selects "Properties" and directly after that press "OK" to Close the Properties-window, the network settings on the virtual network adapters on that host are removed (ip address, subnet mask and default gateway are deleted).
If I then look at running jobs i VMM I can see a job named "Change properties of virtual machine host". This job has five "sub-jobs" (each for every virtual network adapter) named "Update host virtual network adapter".
So it appears that if I open the Properties window on a host in VMM and press OK to Close the window, VMM changes the virtual network adapter settings. the same thing happens if I change some other settings before I Close the window.
Has someone else seen this behaviour before?
