Description Douglas Schilling Landgraf 2016-09-22 04:49:29 UTC 
Description of problem:

RHEV-H 7.3 boot is failing to start these services affecting the hypervisor TUI and virtual machine start.

Version-Release number of selected component (if applicable):

systemd-python-219-30.el7.x86_64
systemd-sysv-219-30.el7.x86_64
systemd-libs-219-30.el7.x86_64
systemd-219-30.el7.x86_64

dbus-glib-0.100-7.el7.x86_64
dbus-1.6.12-17.el7.x86_64
dbus-libs-1.6.12-17.el7.x86_64
dbus-python-1.1.1-9.el7.x86_64

kernel-3.10.0-506.el7.x86_64

How reproducible:
- Install rhev-hypervisor7-7.3-20160921.1
- After auto-registration, storage added into RHEV-M the virtual machine fails to start.(systemd-machined)
or
- In the TUI Menu it will generate an exception when trying to configure keyboard (systemd-localed.service)

Comment 1 Lukáš Nykrýn 2016-09-22 07:39:00 UTC 
This looks like a some problem with the mount namespace. Could you try to remove the Private* and Protect* stanzas from unit-files in those services? And if that helps could you try to find out which of those is causing the issue.

Also do you know what was the last version where this was working? We did not change anything in that area recently.
Comment 2 Douglas Schilling Landgraf 2016-09-23 04:07:06 UTC 
Hi Lukáš, 

(In reply to Lukáš Nykrýn from comment #1)

If I comment PrivateDevices=yes in the services: systemd-localed and systemd-machined everything work again (TUI and start virtual machines). I have tried several combinations and only PrivateDevices affect us.

One thing that called my attention, from: https://www.freedesktop.org/software/systemd/man/systemd.exec.html

<snip>
PrivateDevices=

    Takes a boolean argument. If true, sets up a new /dev namespace for the executed processes and only adds API pseudo devices such as /dev/null, /dev/zero or /dev/random (as well as the pseudo TTY subsystem) to it, but no physical devices such as /dev/sda. This is useful to securely turn off physical device access by the executed process. ***** Defaults to false. *****
Enabling this option will also remove CAP_MKNOD from the capability bounding set for the unit (see above), and set DevicePolicy=closed (see systemd.resource-control(5) for details).Note that using this setting will disconnect propagation of mounts from the service to the host (propagation in the opposite direction continues to work). This means that this setting may not be used for services which shall be able to install mount points in the main mount namespace. The /dev namespace will be mounted read-only and 'noexec'. The latter may break old programs which try to set up executable memory by using mmap(2) of /dev/zero instead of using MAP_ANON.
</snip>

If I understood correctly, the default suppose to be false but currently systemd is shipping it as default true. Is that correct? 

> Also do you know what was the last version where this was working? We did

That's the weird part, the diff shows:

<snip>
    -systemd-219-27.el7.src.rpm
    +systemd-219-30.el7.src.rpm
</snip>

Based on that I have rebuild the RHEV-H with systemd-219-27 and now I see this behaviour that in the past didn't show up.

Anyway, here the full diff between the RHEV-H iso that works against the iso from today with the same systemd but still failing:

Comment 3 Fabian Deutsch 2016-09-23 14:48:05 UTC 
Considering comment 22 I wonder if this is a Node only bug.

If it's easy to reproduce on RHEL, then we need a systemd fix. But if we can't then we should use the workaround of comment 2. We should recognize that we had to add tehse kind of "fixes" for 7.0 and 7.1.
