USB redirect
by Juan Jose 12 Nov '14

12 Nov '14

Hello everybody, I have an oVirt 3.4 deployment and I have some Windows 7 Enterprise 32 bits guests. I can't redirect USB from a Windows 7 client. I'm using remote - viewer as console. Also I have observed something wrong in my administration portal. The oVirt documentation says that I have to select Native USB mode in console properties in VM configuration but after select this mode, it doesn't remain. If I check this value in console configuration again I can see disabled, native mode value have been changed. Is there someone have had this problem?, and how I can solve it?, is it necessary to install in Windows clients us clerk software? Many thanks in advanced. Juanjo.

The oVirt team is pleased to announce that the 3.5 and master nightly snapshot repositories[1] have been update including builds for Red Hat Enterprise Linux 7 (or similar) for testing. Please note that mirrors may need usually one day before being synchronized. If you want to be sure to use latest rpms and don't want to wait for the mirrors, you can edit /etc/yum.repos.d/ovirt-3.5-snapshot.repo or /etc/yum.repos.d/ovirt-master-snapshot.repo commenting the mirror line and removing the comment on baseurl line. Thanks to everyone who will join us testing oVirt! If you're testing oVirt 3.5 nightly snapshot, please add yourself to the test page [2] [1] http://www.ovirt.org/Install_nightly_snapshot [2] http://www.ovirt.org/Testing/oVirt_3.5.1_Testing -- Sandro Bonazzola Better technology.

Hi, Release criteria discussion started on 2014-10-22 and should end today as per current release process [1]. Current options are: 1) keeping the same release criteria we had for 3.5 [2] 2) review the proposed changes [3] and prepare new release criteria for 3.6 Release management for 3.6.0 has been created [4] The key milestones for this release must be scheduled: Key Milestones Release criteria discussion start: 2014-10-22 Release criteria ready: 2014-11-12 Feature freeze: 60 Days before release First Test Day: 45 days before release Release Candidate: 30 days before release Release: 6 months after oVirt 3.5.0 release Two different proposals have been made about above scheduling [5]: 1) extend the cycle to 10 months for allowing to include a large feature set 2) reduce the cycle to less than 6 months and split features over 3.6 and 3.7 Feature proposed for 3.6.0 must now be collected in the 3.6 google doc [9] and reviewed by maintainers. A tracker bug for 3.6.0 has been created [6] and currently shows no blockers. There are 399 bugs [7] targeted to 3.6.0. Excluding node and documentation bugs we have 379 bugs [8] targeted to 3.6.0.
