hi, while testing CR repo one of oVirt users found an issue:

During the "Waiting for the host to become operational in the engine" stage, the hosted-engine-setup fails because of the following VDSM requirement:

"VIR_MIGRATE_AUTO_CONVERGE not found in libvirt, support for clusterLevel >= 3.6 is disabled. For Fedora 20 users, please consider upgrading libvirt from the virt-preview repository"

According to [1], libvirt version >= 1.2.3 is required.

Any suggestion where to get this packages + dependencies for CentOS 7?

[...]

OTOH, I wrote the above only because Centos 7.1 is not yet released, so one must use the RC (Release Candidate) Centos repos, and because I can't recommend any extra repo.

For the records,

I installed libvirt 1.2.8 from CR repo: yum --enablerepo=cr install libvirt-daemon

This broke vdsm because of a "no connection driver available for qemu:///system" error.

The problem was that libvirt 1.2.8 "failed to load module /usr/lib64/libvirt/connection-driver/libvirt_driver_qemu.so" and "/usr/lib64/libvirt/connection-driver/libvirt_driver_qemu.so: undefined symbol: virStorageFileCreate".

The solution is to upgrade device-mapper-libs: yum --enablerepo=cr upgrade device-mapper-libs

Conclusion: A device-mapper dependency should be added to libvirt

This are my installed packages:

device-mapper-1.02.93-3.el7.x86_64 device-mapper-event-1.02.93-3.el7.x86_64 device-mapper-event-libs-1.02.93-3.el7.x86_64 device-mapper-libs-1.02.93-3.el7.x86_64 device-mapper-multipath-0.4.9-66.el7.x86_64 device-mapper-multipath-libs-0.4.9-66.el7.x86_64 device-mapper-persistent-data-0.3.2-1.el7.x86_64 libvirt-client-1.2.8-16.el7_1.1.x86_64 libvirt-daemon-1.2.8-16.el7_1.1.x86_64 libvirt-daemon-config-nwfilter-1.2.8-16.el7_1.1.x86_64 libvirt-daemon-driver-interface-1.2.8-16.el7_1.1.x86_64 libvirt-daemon-driver-network-1.2.8-16.el7_1.1.x86_64 libvirt-daemon-driver-nodedev-1.2.8-16.el7_1.1.x86_64 libvirt-daemon-driver-nwfilter-1.2.8-16.el7_1.1.x86_64 libvirt-daemon-driver-qemu-1.2.8-16.el7_1.1.x86_64 libvirt-daemon-driver-secret-1.2.8-16.el7_1.1.x86_64 libvirt-daemon-driver-storage-1.2.8-16.el7_1.1.x86_64 libvirt-daemon-kvm-1.2.8-16.el7_1.1.x86_64 libvirt-lock-sanlock-1.2.8-16.el7_1.1.x86_64 libvirt-python-1.2.8-7.el7_1.1.x86_64
