I am comparing three sources of information about MAC addresses assigned to dataplane interfaces on experimental nodes:

• The output of /sbin/ifconfig on the node itself (which should be authoritative)
• The output of sliverstatus run by the experimenter on the slice to which the node belongs
• The experiment details page as viewed by an admin, e.g. ​https://boss.utah.geniracks.net/showexp.php3?experiment=363#details

These three data sources agree given a physical node. However, given an OpenVZ container, the second data source is incorrect, and the third is missing.

I've only tried to verify this once, using the sliver pgeni-gpolab-bbn-com/ecgtest, which contains the mapping:

Physical Node Mapping:
ID              Type         OS              Physical
--------------- ------------ --------------- ------------
phys1           dl360        FEDORA15-STD    pc3
virt1           pcvm         OPENVZ-STD      pcvm5-1 (pc5)

For this experiment, i see:

• For the physical node interface, everything is correct:

  MAC addrs reported for phys1:0 == 10.10.1.1
    E8:39:35:B1:4E:8A: from /sbin/ifconfig eth1 run on phys1 (authoritative)
    e83935b14e8a:      from sliverstatus as experimenter (correct)
    e8:39:35:b1:4e:8a: from: https://boss.utah.geniracks.net/showexp.php3?experiment=363#details (correct)
  

• For the virtual node interface, sliverstatus reports an incorrect MAC, and showexp.php3 reports no MAC at all:

  MAC addrs reported for virt1:0 == 10.10.1.2
    82:01:0A:0A:01:02: from /sbin/ifconfig mv1.1 run on virt1 (authoritative)
    00000a0a0102:      from sliverstatus as experimenter (incorrect: first four digits are wrong)
    -                : from https://boss.utah.geniracks.net/showexp.php3?experiment=363#details (not reported)
  

I created an OpenVZ container on pc5.utah.geniracks.net. I notice that /var/log within the container appears to be empty. I would expect logs from the container's userspace to be stored in /var/log within the container for the experimenter to access.

Output of /var/log, being empty:

Uname, fyi:

[chaos@virt1 ~]$ uname -a

Nodes which are successfully booted from the images FEDORA15-STD and FEDORA15-OPENVZ-STD in utah.geniracks.net, appear not to work with the iLO remote console. The java console app reports "No Video".

I've corroborated this just now, on:

• 155.98.34.104, iLO for pc3, which is running FEDORA15-OPENVZ-STD for the experiment emulab-ops/shared-nodes
• 155.98.34.105, iLO for pc4, which is running FEDORA15-STD for the experiment pgeni-gpolab-bbn-com/ecgtest

During testing of IG-ADM-1, i successfully used the remote consoles for pc3 and pc4 at other times. So i believe this is not working right now because of the fedora images, rather than because of a connectivity problem with those particular hosts.
