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=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. Neil Wilson.
