Hello All,
Preparing to ovirt-engine 3.2 the entire "vdsm-bootstrap" bootstrap was
re-written from scratch into more pluggable and flexible implementation, available at git
master and nightly snapshots.
As far as packaging is concerned there are now two more dependencies to ovirt-engine:
* otopi -- oVirt Task Oriented Pluggable Installer/Implementation
* ovirt-host-deploy -- oVirt host deploy tool
These packages replace the legacy vdsm-bootstrap package that was distributed with vdsm.
Git repositories are available at at[1][2].
Documentation is available at Git repositories - README*.
Builds are available at usual place[3].
Bugzilla components will be available shortly.
Change log is attached.
There is no change in the way the engine is performing the host deployment process in term
of user experience, other than event log messages during deployment were improved.
The log of the deployment is fetched from host and stored at engine machine at
/var/log/ovirt-engine/host-deploy, on host it is at /tmp/ovirt-host-deploy*.log and
deleted when fetched to engine.
Among other features, the ovir-host-deploy package can be installed manually on host and
executed to prepare host for installation, in future we may be able to add host to engine
without performing the deployment process, for now it will be usable for integration
tests.
The internals are completely different, instead of having 3 different bootstrap
sequences:
1. host install
2. ovirt-node install
3. ovirt-node approve
We now have single sequence which is common to host and node installation or
re-installation, end result is much simpler implementation.
Please report any issues even minor issues, so we can stabilize it for 3.2 release.
Best Regards,
Alon Bar-Lev.

Change Log
* offline packager feature.
* tuned is installed with virtual-host profile.
* initial implementation based on otpoi.
* implementation is based on legacy vdsm-bootstrap pacakge functionality.
* legacy-removed: legacy VDSM (<3.0) config upgrade.
* legacy-removed: change machine width core file
# echo /var/lib/vdsm/core > /proc/sys/kernel/core_pattern
* legacy-removed: kernel version test, package dependency is sufficient.
* legacy-removed: do not add kernel parameter processor.max_cstate=1
warn if not have constant_tsc
https://bugzilla.redhat.com/show_bug.cgi?id=770153
* legacy-change: io elevator scheduler set in kernel command-line
use either udev rule in vdsm package or tuned.
* legacy-change: vdsm libvirt reconfigure
vdsm is reconfigured with file based trigger instead unsupported systemd
init.d parameter.
* legacy-change: distribution checks are simpler based on Python platform,
minimum:
- rhel-6.2
- fedora-17
* legacy-change: minimum vdsm version is taken from engine not hard coded.
* legacy-change: pki is now using m2crypto to generate certificate request
and parse certificates.
* legacy-change: use iproute2 instead of python ethtool to avoid another
dependency for host name validation.
* legacy-change: use iproute2 instead of reading /proc/net/route for route
information and interface information.
* legacy-change: do not use vdsm.netinfo for vlan and bonding as it requires
/usr/share/vdsm modules, and it is trivial anyway.
* legacy-change: use vdsm-store-net-config script to commit network config
instead of internal duplicate implementation.
* legacy-change: /etc/vdsm/vdsm.conf is overridden unless VDSM/configOverride
environment is set to True
* legacy-change: /etc/vdsm/vdsm.conf is not read of fake_qemu.
set VDSM/checkVirtHardware environment to False to avoid hardware detection.
* legacy-change: following gluster packages not installed:
- glusterfs-rdma
- glusterfs-geo-replication
