Still not getting DHCP IP's assigned on the containers running in the VM... Again, I see the DHCP packets coming in on the 'vnet0' int on the oVirt hypervisor hosts having the VM which has the containers: [root@ovirt-node-03 ~]# tcpdump -i vnet0 -vvv -s 1500 '(port 67 or port 68)' 11:13:38.689970 IP (tos 0x10, ttl 128, id 0, offset 0, flags [none], proto UDP (17), length 328) 0.0.0.0.bootpc > 255.255.255.255.bootps: [udp sum ok] BOOTP/DHCP, Request from 32:33:32:64:30:65 (oui Unknown), length 300, xid 0xd0f70f67, secs 247, Flags [none] (0x0000) Client-Ethernet-Address 32:33:32:64:30:65 (oui Unknown) Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: Discover Hostname Option 12, length 9: "blitsnorp" Parameter-Request Option 55, length 13: Subnet-Mask, BR, Time-Zone, Default-Gateway Domain-Name, Domain-Name-Server, Option 119, Hostname Netbios-Name-Server, Netbios-Scope, MTU, Classless-Static-Route NTP END Option 255, length 0 PAD Option 0, length 0, occurs 30 But I do not see the MAC from the container in the relevant oVirt bridge that the VM is connected to (in this case, port 3 on the bridge): [root@ovirt-node-03 ~]# brctl showmacs 207-net | grep "^ 3" 3 00:1a:4a:16:01:57 no 0.13 (VM eth0 MAC) 3 fe:1a:4a:16:01:57 yes 0.00 (veth connection from VM) 3 fe:1a:4a:16:01:57 yes 0.00 (why are two showing???)

OK, installed on all hypervisor hosts (and the engine host as well) - do I need to bounce the VMs having containers now, or not?

Yes, of course: you have to reboot all the involved VMs.

OK. This goes on just the engine host, or on the hypervisor hosts? (or both?)

On all the hosted-engine hosts

...

Also (and not trying to be insulting here), is this documented anywhere? I didn't run across this dependency in anything I read...

Good question

...

No, I didn't see (notice) that step / instructions anywhere... How to do that?

Did you also correctly installed vdsm-hook-macspoof on all of your hosted-engine hosts?

yum install vdsm-hook-macspoof
