DHCP Client in Guest VM does not work on ovirtmgmt

Hello, Is there any special config to usage dhcp client on Guest VM using ovirtmgmt/ovirtmgmt vnic profile ? Currently I have a VM using the ovirtmgmt/ovirtmgmt NIC profile and this interface is configured as DHCP client, and this does not work when using ovirtmgmt/ovirtmgmt as NIC profile. But if I assign manual IP address from the same range of DHCP server the comunication it works. And If usage other NIC profile in other VLAN with other DHCP server it works. It seems ovirtmgmt/ovirtmgmt profile filter the DHCP protocol. Could someone has idea to allow DHCP protocol works on ovirtmgmt/ovirtmgmt NIC profile? Best regards Carlos

Only to increase the details? With tcpdump on ovirt node it seems that DHCP is pass by interfaces [root@srv-virt8 ~]# tcpdump -i any -pvn port 67 and port 68 tcpdump: listening on any, link-type LINUX_SLL (Linux cooked), capture size 262144 bytes 16:16:52.605855 ethertype IPv4, IP (tos 0x10, ttl 128, id 0, offset 0, flags [none], proto UDP (17), length 328) 172.20.0.254.bootps > 172.20.0.228.bootpc: BOOTP/DHCP, Reply, length 300, xid 0x2f8f346e, Flags [none] Your-IP 172.20.0.228 Client-Ethernet-Address 56:6f:a5:6a:00:06 Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: Offer Server-ID Option 54, length 4: 172.20.0.254 Lease-Time Option 51, length 4: 7200 Subnet-Mask Option 1, length 4: 255.255.255.0 Default-Gateway Option 3, length 4: 172.20.0.254 Domain-Name Option 15, length 19: "mydomain.com" Domain-Name-Server Option 6, length 4: 172.20.0.254 16:16:52.605855 ethertype IPv4, IP (tos 0x10, ttl 128, id 0, offset 0, flags [none], proto UDP (17), length 328) 172.20.0.254.bootps > 172.20.0.228.bootpc: BOOTP/DHCP, Reply, length 300, xid 0x2f8f346e, Flags [none] Your-IP 172.20.0.228 Client-Ethernet-Address 56:6f:a5:6a:00:06 Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: Offer Server-ID Option 54, length 4: 172.20.0.254 Lease-Time Option 51, length 4: 7200 Subnet-Mask Option 1, length 4: 255.255.255.0 Default-Gateway Option 3, length 4: 172.20.0.254 Domain-Name Option 15, length 19: "mydomain.com" Domain-Name-Server Option 6, length 4: 172.20.0.254 16:16:52.605855 IP (tos 0x10, ttl 128, id 0, offset 0, flags [none], proto UDP (17), length 328) 172.20.0.254.bootps > 172.20.0.228.bootpc: BOOTP/DHCP, Reply, length 300, xid 0x2f8f346e, Flags [none] Your-IP 172.20.0.228 Client-Ethernet-Address 56:6f:a5:6a:00:06 Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: Offer Server-ID Option 54, length 4: 172.20.0.254 Lease-Time Option 51, length 4: 7200 Subnet-Mask Option 1, length 4: 255.255.255.0 Default-Gateway Option 3, length 4: 172.20.0.254 Domain-Name Option 15, length 19: "mydomain.com" Domain-Name-Server Option 6, length 4: 172.20.0.254

I'm having the same problem :( My guest vms with nick profile on ovirtmgm does not get address by dhcp client. How can I fix it? cheers im

FYI my tcpdump show the same result as you posted. But the guest vm no receive the address. Any idea:?

Hi Dominik, Im my case, I dont have filter definied on ovirtmgmt vNIC profile, but with or without filter (even VM is stoped) the DHCP does not work. it follow the tcpdump from VM

Hi, any suggestion about it?

Please share the versions used on the host and guest. Have you upgraded or change something? (by versions, I mean OS, oVirt and anything you think is related) A fast and dirty check will be to examine if this is caused with firewalld on the host or guest. Please try to disable it and make sure no iptables settings appear.

Hey Carlos, Im still having the same problem here. My bond interface is configured as mode=2 same you. I tested in other server Bond Interface with mode 2 vlan and bridge interface using this bond as DHCP client and it works. But using ovirt no sucess. Did you discovery anything? regards

Hi @hotomoc, Nothing, it seems there are some filter or like this. Maybe some expert could help us. regards Carlos

Hi Edward, Yes, it is disabled . As screenshot. https://pasteboard.co/IEZS49Z.png And I already tested some filter as clean-traffic-gateway, but no success. Any other idea? Regards Carlos

I thought that was it. I remembered some experience I had with a test install that recommended turning the network filter off. You probably already did this, but when you turn off filtering or make other changes to the logical network like MTU size you must completely shutdown the attached VMs and restart them from oVIrt engine to pickup the change for their network interface. Restarting networking in a VM from within its OS won't pick up the logical network change at the necessary KVM/qemu/libvirt levels. There should a way to verify the various virtual interfaces don't have any filtering configured or enabled, On Sun, Nov 3, 2019 at 11:16 AM <ccesario@blueit.com.br> wrote:

Hello, can you see the traffic on the tap e.g. vnet0 device that is attached to the VM? Traffic filtering from libvirt is stored in ebtables. Can you take a look into them and see if there is any suspicious rule? (ebtables -L) Maybe track the packet drop here if your VM is sending DHCP requests. If everything there seems alright. I would suggest going through the chain and check the bridge interface if the DHCP packets are going through it. Hopefully this helps. Regards, Ales

Ah my bad it is ebtables -t nat -L.
Can you share how your network topology of the host?

Hi Ales,

Hi Ales, have you any new tip about this? regards, Carlos

The output of "tcpdump -i ovirtmgmt -pvn port 67 and port 68" in https://pastebin.com/a2DEyL0e looks like the DHCP reply does not reach the ovirtmgmt bridge. Is the ovirtmgmt bridge / network attachment on the host able to receive configuration by DHCP? On Wed, Nov 6, 2019 at 7:08 PM <ccesario@blueit.com.br> wrote:

Yes, it is able, it is on the same VLAN. If I configure the ovirtmgmt interface as DHCP, it works. The DHCP delivery IP to ovirtmgmt interface. The problem it seems with VMS using this network.

Hi folks, After several tests and a bit talk with Dominik via IRC, the problem it was found. To sum up, the problem it was in my side, once Im using bonding mode 2 (I read in some local that no needed switch config), but Dominik correct me that it is needed a config in switch side. After it the DHCP client it worked as expected. IMHO would be nice, Ovirt support bond0 or nic teaming, like VMware, where in some cases there is no needed special config on network/switch side and we still have some redundancy and availability. Thank you all by help. Regards Carlos
