How to set up Hyper-v server replication?

Question

Hyper-V

Hello, There are several Hyper-v hypervisors, virtual machine replication was configured, after that it was necessary to change the router on the site and in the branches, as a result, after changing the router (centos) to (Kerio control), the replica stopped happening. Apparently somehow there is no communication between servers when setting up a replica. Pings from hypervisors (to each other) reach, settings are checked, everything is normal. the last remark was made just before changing routers. how to determine what cuts traffic.. I sin on the work of a proxy. Error 0x00002efe.

Answer 1

For replication, Hyper-V uses the following ports and protocols:
1 .Http+Https to authorize one host to another
2. SMB - to share delta disk system files and share RAM files during live migration if using SMB mode (not TCP)
Check operation of these protocols, ensure that the two nodes are fully connected. Check how DNS works, whether everything is resolved. Remove proxies from these nodes, traffic should go directly.
If all else fails, you need a network map to better understand your infrastructure.

Answer 2

Well, obviously, problems with network connectivity. Check the MTU settings on all hypervisors and switch ports to which they are connected. Run pings with large packet sizes and see if they are as crisp as regular pings.
