[Users] Packet loss to guests

[Neil]

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-engine-backend-3.1.0-3.19.el6.noarch
ovirt-engine-notification-service-3.1.0-3.19.el6.noarch
ovirt-image-uploader-3.1.0-16.el6.noarch
ovirt-engine-genericapi-3.1.0-3.19.el6.noarch
ovirt-iso-uploader-3.1.0-16.el6.noarch
ovirt-engine-restapi-3.1.0-3.19.el6.noarch
ovirt-engine-tools-common-3.1.0-3.19.el6.noarch
ovirt-engine-sdk-3.2.0.8-1.el6.noarch
ovirt-engine-webadmin-portal-3.1.0-3.19.el6.noarch
ovirt-engine-cli-3.2.0.5-1.el6.noarch
ovirt-log-collector-3.1.0-16.el6.noarch
ovirt-engine-setup-3.1.0-3.19.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
       inet6 addr: fe80::21a:4aff:fea8:0/64 Scope:Link
       UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
       RX packets:5050 errors:0 dropped:0 overruns:0 frame:0
       TX packets:255 errors:0 dropped:0 overruns:0 carrier:0
       collisions:0 txqueuelen:1000
       RX bytes:490762 (479.2 KiB)  TX bytes:32516 (31.7 KiB)

Ethernet controller: Red Hat, Inc Virtio network device

Has anyone got any ideas? Have I set something up wrong?

Any help or advice is greatly appreciated.

Regards.
