Can't talk between virtual servers on br1

Submitted by sfatula on Mon, 08/21/2017 - 16:03

I have a cloudmin server with 5 virtual hosts, 1 windows, 1 centos 6, 3 centos 7. br0 is the wan interface, br1 is the lan interface (local only). Between any of these hosts, I can ping the LAN address of any of the others (192.168.2.x) via br1. Except, for 2 machines, one of those is centos 6, one is centos 7. Remember, they can ping any other virtual machines though and vice versa. So, between those 2, centos 6 can ping centos 7, but not vice versa. Not sure how to debug this, not familiar with virtualization as far as commands, etc. So, all machines can ping the one machine centos 6 machine cannot ping just fine, even the cloudmin host can. Yes, they have different ips.

I found the problem. I cloned a virtual machine via backup and restore onto the same cloudmin server. Well, it kept the same mac address for eth1. Not sure why or where that is stored, so, just made one up for the machine and it works now. Curious as to where "assign automatically" get's its mac address from for eth1? Couldn't find it.

Ok, I see how this MAC clash could happen - it will be prevented in the next Cloudmin release.
