CentOS 7 KVM and QEMU 2.+

Post #1 of 6 (6540 views)

Hello guys,

I'm struggling at finding a qemu(-kvm) version up-to-date for CentOS 7 with official repositories
and additional EPEL.

Currently the only package named qemu-kvm in these repositories is *qemu-kvm-1.5.3-86.el7_1.8.x86_64*, which is a bit outdated.

As what I understand QEMU merged the forked qemu-kvm into the base code since 1.3 and the Kernel is shipped with KVM module. Theoretically we can just install qemu 2.+ and load KVM in order to use nova-compute with KVM acceleration, right ?

The problem is that the packages openstack-nova{-compute} have a dependencies with qemu-kvm. For example Fedora ships qemu-kvm as a subpackage of qemu and it appears to be the same in fact, not the forked project [1].

In a word, guys how do you manage to have a QEMU v2.+ with latest libvirt on your CentOS computes nodes ?
Is somebody using the qemu packages from oVirt ? [2]

Thanks,
See you

Both the RHEV and RHEL Openstack distributions are using the qemu 2.x
packages. These are based on packages from the oVirt project.

The RDO rpms work fine with the oVirt qemu packages. This is what we are
using.

You can find more information about which RedHat distro spins get which
version of qemu here:

Hi,

What about the CentOS Virt SIGâ€™s repo at

http://mirror.centos.org/centos-7/7/virt/x86_64/kvm-common/

(and the testing repos at:
http://buildlogs.centos.org/centos/7/virt/x86_64/kvm-common/ )?

These contain newer versions of the qemu-* packages.

Cheers,
Arne

I've been building these and running them on CentOS for a while,
mainly to get RBD support. They work fine.

Thanks everybody for your great inputs, I'll consider the 3 options for
our platform.

Thanks,
See you

I agree with Erik! Source RPM packages from RH are a good option.

Best,
