Subject: RE: [ovirt-users] virt-in-virt problem: DHCP failing for a container in a oVirt
VM
OK, I did, and... 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???)
(notice no entry for MAC 32:33:32:64:30:65 from the container on the VM)

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.

On all the hosted-engine hosts

Good question
