[ATN] [ovirt-engine] engine master logging
by Alon Bar-Lev 23 Oct '14

23 Oct '14

Hello All, Thanks to Martin Perina efforts[1] the ovirt-engine logging was cleaned up significantly throughout the engine. 1. Logging Facade is slf4j. 2. Logging backend is jboss logging at jboss and java.util.logging at standalone. 3. No more commons-logging, log4j, combinations nor proprietary loggers. The org.ovirt.engine.core.utils.log.LogFactory and org.ovirt.engine.core.utils.log.Log are depreciated now, the correlation id is managed using logging MDC, so no need to use wrapper, and correlation has much wider effect, as also 3rd parties log records are attached with correlation id. We will start to push changes to remove the usage of these classes in favor of plain slf4j loggers. Quick lineup... 1. Usage: import org.slf4j.Logger; import org.slf4j.LoggerFactory; class x { private static final Logger log = LoggerFactory.getLogger(x.class); } 2. slf4j logger javadoc is here[2]. 3. Crash course: // simple string log.info("string"); // string with exception and stack trace log.info("string", exception); // string with vars, logger will call argN.toString() for each {}. log.info("string {} {} {}", arg1, arg2, arg3); 4. *NOTICE* Major difference than what we had: Exception arguments are not "magically" detected. // previous (utils Log): "exception" magically detected. log.infoFormat("string {0}", arg1, exception); // new (slf4j): log.info("string {}", arg1); log.info("Exception", exception); // better new (slf4j): log.info("string {}", arg1); log.debug("Exception", exception); Please do not hesitate to raise any related issue you may find. Regards, Alon Bar-Lev. [1] https://bugzilla.redhat.com/show_bug.cgi?id=1109871 [2] http://www.slf4j.org/api/org/slf4j/Logger.html

logging.captureWarnings only in Python 2.7, EL6 broken
by Ondřej Svoboda 21 Oct '14

21 Oct '14

Hi all, Sandro pointed out that tests are failing on File "../tests/testrunner.py", line 33, in <module> logging.captureWarnings(True) AttributeError: 'module' object has no attribute 'captureWarnings' The code, conditionally using the function also in our daemon, has been introduced on http://gerrit.ovirt.org/#/c/34034, adding support for 'warnings' module. I have dug in Python changelogs and found that captureWarnings has, sadly, never been backported to Python 2.6. I have seen another project [1] employ the function only optionally. But for us, this probably makes the support for 'warnings' module in logging also optional in effect. Saggi, I wanted to notice you about this. Do you think 'warnings' could be made to work in a different way, or are they only possible on platforms having Python 2.7+?

[ANN] oVirt 3.5 GA Releases
by Sandro Bonazzola 20 Oct '14

20 Oct '14

The oVirt Project is pleased to announce the general availability of its sixth formal release, oVirt 3.5, as of October 17, 2014. oVirt is an open source alternative to VMware vSphere, and provides an excellent KVM management interface for multi-node virtualization. oVirt is available now for Fedora 19, Fedora 20, Red Hat Enterprise Linux 6.5, and CentOS 6.5 (or similar) and allow you to use Red Hat Enterprise Linux 7 and CentOS 7 too as node and for running Hosted Engine. New features include: Live Merge ---------- If an image has one or more snapshots, oVirt 3.5's merge command will combine the data of one volume into another. Live merges can be performed with data is pulled from one snapshot into another snapshot. The engine can merge multiple disks at the same time and each merge can independently fail or succeed in each operation. Import Storage Domain This latest release expands oVirt's feature of importing ISOs and exporting storage domains to expand support for importing an existing data storage domain. Based on information stored in the storage domain, oVirt can revive entities such as disks, virtual machines, and templates in the setup of any data center to which the storage domain is attached. Advanced Foreman Integration ---------------------------- oVirt 3.5 adds the capability to provision and add hypervisors to oVirt from bare metal. Foreman is a complete lifecycle management tool for physical and virtual servers. Through deep integration with configuration management, DHCP, DNS, TFTP, and PXE-based unattended installations, Foreman manages every stage of the lifecycle of your physical or virtual servers. Integrating Foreman with oVirt helps add hypervisor hosts managed by Foreman to the oVirt engine. Enhanced Authentication, Authorization and Accounting Support ------------------------------------------------------------- A new architecture has been built for oVirt 3.5's authentication, authorization and accounting (AAA) system. The enhancements will provide a clear separation of authentication from authorization and provide a developer API to develop custom extensions for authentication and authorization. New PatternFly Interface ------------------------ oVirt 3.5 will have a new look and feel, using PatternFly, the open interface project. The new look and feel aims to maintain the colors and spirit associated with oVirt, while updating it with a new, modern, sleek, and minimal look. The minimal design allows complex screens to look cleaner and airier, and lets the user focus on the data and the tasks by removing all extraneous visual elements. Advanced Scheduling with Optaplanner ------------------------------------ The Optaplanner is a new service that takes a snapshot of a cluster (a list of hosts and VMs) and computes an optimized VM-to-Host assignment solution. Optimization will is done on per Cluster basis. The administrator can use this information as a hint to tweak the cluster to better utilize resources. This release of oVirt also includes numerous bug fixes. See the release notes [1] for a complete list of the new features and bugs fixed. A new repository has been created and will be automatically enabled by installing / upgrading ovirt-release35 package. See release notes page for further instructions about install / upgrade. A new oVirt Live iso is also available [2] and a new oVirt Node iso will be available soon.
