Non-xen machines are reported as being xen VMs

[Björn Tillenius]

Both my oneiric and precise machines are being reported as being xen VMs. Looking closer at the detection code, it checks for the presence of /sys/bus/xen, which does indeed exist. It seems like we have to look at what's inside that directory. On my real machines, /sys/bus/xen/drivers/ and /sys/bus/xen/devices/ exist, but are empty. On my linode xen vm, the drivers/ and devices/ directories do contain some files.

Canonistack instances also seem to be wrongly reported as xen vms, when they should be kvm ones.

Lucid doesn't seem to be affected. I haven't check what happens for natty.

My bare metal client is also recognized as "xen", and does not seem to send hardware information to Landscape server.

Status changed to 'Confirmed' because the bug affects multiple users.

[Andreas Hasenack (ahasenack)]

It should be fixed in the 12.04.2-0ubuntu1 package that is in precise. Can you try?

[Nobuto Murata (nobuto)]

@Andreas

Sorry for late testing.
Though my bare metal machine is not reported as xen, hardware information is not still shown on Landscape Web UI.

My environment:
 * current up-to-date Precise
 * landscape-{client,common} 12.04.3-0ubuntu1
 * time elapsed since resistered with Landscape - 48+ hours
 * /etc/landscape/client.conf

Hardware information requires a new client which is currently undergoing SRU, see bug #978884. This bug will also be marked "fix released" once that SRU is out, since it fixes it for lucid, natty and oneiric.

[Nobuto Murata (nobuto)]

@Andreas
I don't think my issue is related to Bug #978884.
#978884 handles SRU for oneiric or older, but I have used the newest package 12.04.3-0ubuntu1 on *Precise*.

BTW, though hardware information is not shown, indeed it's reported as a non-xen (bare metal) machine.
So I will mark this bug for Precise task as Fix Released.

Is "hardware information not shown" issue tracked somewhere?

The hardware information plugin runs once a day, have you given it enough time? Is the client communicating properly with the server, i.e., do activities complete, is monitoring data up-to-date, etc?

[Andreas Hasenack (ahasenack)]

Oh, I'm sorry, the new hardware page isn't in landscape production yet. We expect it to be deployed next week, it's currently undergoing testing among a host of other changes.
