qemu update 1.5.3 -> newer?
Hi
Our cloudstack 4.11.1 installation works with qemu-kvm 1.5.3, which is
shipped with standard Centos7.
Anyone has a guide about safe way to upgrade to a newer version of qemu?
Best regards,
Jevgeni

Yes.
Followed Simon's suggestion. Worked flawlessly.
Thanks Simon!

Hello,
Simon explained it better than me. We are running qemu-kvm-ev with
4.9.x cloudstack for about a year and had no issue with. We moved to
it due to better ceph performance and lower latencies. Before moving
all your servers test them for performance an stability. On Wed, Sep

So a couple of things to note here.
RHEL (and hence Centos) backport a lot of features, so 1.5.x is later than it might seem on paper. Take a look at the changelog on the RPM for details.
The EV version of qemu is derived from the RHEL packing for ovirt and other RHEL virtualization products, but it's not part of the distro itself. However, it is designed to be an in-place upgrade for the 1.5.x release included in the distro.
The current rpm release is 2.10 and it can be installed on centos via the following commands:
yum install centos-release-qemu-ev
yum install qemu-kvm-ev
We've been testing it our QA environment on Centos 7, as it's required for some new IOPS bursting features we're working on for KVM right now. Thus far it seems to function exactly as expected with CloudStack and you can even live migrate between hosts running 1.5.x and 2.10.

Doesn't look to be active. The page has zero information about my questions
and is not maintained either.
Other hints?

There is a SIG for centos that is running newer versions of
qemu/libvirt. You can find more info about it here
