[Xen-users] No Network info for hardware VMs using XM Top

Using Xen 3.30 on what should be nearly identical Xen servers, each of
the servers shows no packets at all under network in xm top unless the
VM is using the Windows para drivers, all the interfaces for each vm
appear but no packets are shown. Does anyone know how I can get standard
HVM NIC bridge interfaces to register traffic in XM top?

Thanks,

Rob

have you assigned names (like vivwin1, vifhost1, etc) to each
interface in the config files? I read somewhere that this is a
problem.

What happens if you do a "ifconfig vifhost1" - if "vifhost1"
is the
interface of one of the domU''s?

RE: [Xen-users] No Network info for hardware VMs using XM Top

Rudi is correct about the vifname parameter.  However, that is for
PV usage, and don''t know if ii is a Xen problem or a distro problem.
Regardless, with HVM, it doesn''t affect you.  I''m pretty sure
what you want
can''t be done, presumably because of how the TAP interfaces are set up.
That said, you would have to install something on the HVM machines if you
want to monitor their HVM traffic usage.  This might have changed, but it
seems unlikely.  Of course, I would love to be corrected by someone with
more up-to-date Xen knowledge.

RE: [Xen-users] No Network info for hardware VMs using XM Top

Hi Rudi,

I have not assigned names to the virtual interfaces. They appear in
ipconfig with autogenerated names (eg.vif59.1 for the second NIC on the
VM with an ID of 59).

Here is the result of "ifconfig vif59.1":
[root@mrhappy ~]# ifconfig vif59.1
vif59.1   Link encap:Ethernet  HWaddr FE:FF:FF:FF:FF:FF
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:32
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

Do I need to assign the Vifs a name?


Thanks again,


Rob Dunkley
