Hi guys,
I've got a bit of a strange one, I'm setting up an internal ovirt
system Centos 6.3 64bit dreyou repo...
and I'm getting lots of packet loss on the guest I've installed, the
packet loss doesn't happen on the physical hosts, only the VM gets it,
when communicating from and to it.
1 node(Centos 6.3 64bit)
vdsm-4.10.0-0.46.15.el6.x86_64
vdsm-cli-4.10.0-0.46.15.el6.noarch
vdsm-xmlrpc-4.10.0-0.46.15.el6.noarch
vdsm-python-4.10.0-0.46.15.el6.x86_64
The engine(also Centos 6.3 64bit(engine has local NFS storage which
the node connects to)
ovirt-engine-userportal-3.1.0-3.19.el6.noarch
ovirt-engine-dbscripts-3.1.0-3.19.el6.noarch
ovirt-engine-3.1.0-3.19.el6.noarch

ovirt-iso-uploader-3.1.0-16.el6.noarch

ovirt-engine-jbossas711-1-0.x86_64
ovirt-engine-config-3.1.0-3.19.el6.noarch
Both the node and engine have bonded interfaces all NICS are intel
82574L gigabit and the managed switch reflects gigabit on each of the
ports.
The ifcfg-bond0 is below...
DEVICE=bond0
IPADDR=192.168.0.9
NETWORK=192.168.0.0
NETMASK=255.255.255.0
USERCTL=no
BONDING_OPTS=mode=2
BOOTPROTO=none
MTU=1500
ONBOOT=yes
Then the ifcfg-eth0 and eth1 are almost identical...
DEVICE=eth2
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
MTU=1500
BOOTPROTO=none
These are the network details on the guest, as you can see, there are
no network errors showing on the guest at all, which is strange....
eth0 Link encap:Ethernet HWaddr 00:1A:4A:A8:00:00
inet addr:192.168.0.12 Bcast:192.168.0.255 Mask:255.255.255.0

Has anyone got any ideas? Have I set something up wrong?
Any help or advice is greatly appreciated.

Hi Neil,
I had a similar issue with my oVirt environment with some vms.
The issue on my side was oVirt and RHEV environment in the same subnet
and conflicting MAC addresses on some vms (as both use the same MAC
range and I didn't change this with engine-config).
So can you check if this MAC our your vm is in use by an other host/vm
(maybe from a KVM installation)?

Thanks Rene, I'll look into your suggestions.
I don't think it's a conflicting MAC as there is only 1 guest, but
will check it out.
Would you advise running the engine and nodes on a separate network
range to my existing network rather?
Thanks.
Regards.
Neil Wilson.

Hi,
If you don't have another oVirt / RHEL KVM host in the same network than
MACs want be an issue. So it's totally save to have oVirt in the same
network as all other systems.
I see in your email that you use bonding mode 2. This shouldn't cause
issues with switches, but I think I had an issue with RHEV (bond 2) and
a Cisco switch once on customer side - please don't ask me for details
on what their network admins changed to make this setup work.
Can you try bonding mode 0 (active-backup) and check if you still have
packet loss?
