[Users] Packet loss to guests
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

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