Hi,
a few weeks ago we installed a new ESXi environment and everything is ready. After some adjustments on the firewall we can now migrate switched off VMs from the old construct to the new one. But if we try to migrate running VMs we get error messages. At the source vCenter the bar goes up to 45% and then breaks down. In the target vCenter, it stays at zero %. The error is:
"The destination host did not receive data from the source host on the vMotion network"
vmkping from the target host to the vMotion IP of the source host is missing, so I first suspected a firewall/network problem. But if I put a normal Windows computer into the new vMotion network (same port group etc.) it can be pinged.
The construct is as follows:
-separated storage
-dvSwitch source and target 6.0 because of compatibility
-settings on the dvSwitch are identical.
-old vCenter 6.5
-old ESXi mixed from 5.5 - 6.5 via different vCenter 6.5 Cluster
-new vCenter 6.7
-new ESXi 6.7
-new management network, old management network, new vMotion network and old vMotion network are all different VLANs.
->Both management networks can radio into both vMotion networks and among each other.
->the vMotion networks can see each other
If you need more information, I'll be happy to deliver it.
Many thanks and greetings
Aaron
