Yes, you can.
In fact you can use the binaries from the ovirt repo itself, no need to rebuild.
Thank you!
In fact - I can't use raw binaries from the ovirt repo itself,
because these qemu-kvm binaries contains one bug,
which is already fixed in Debian:
If you want to migrate Windows from hardware node
to VM using CentOS 7.1 on hardware node and libvirt xml config:
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
.....
<qemu:commandline>
<qemu:arg value='-acpitable'/>
<qemu:arg value='file=/sys/firmware/acpi/tables/SLIC'/>
</qemu:commandline>
</domain>
Winodws not working correctly in this case, because Windows requires,
what oem_id and oem_table_id from SLIC must be also placed
into oem_id and oem_table_id of RSDT.
Debian version of qemu-kvm contains workaround for this windows bug,
and using Debian - Windows VM will works fine. But CentOS packages
does not contain such workaround, so qemu-kvm-ev now must be patched
manually with each new release.
Patch already was created by Michael Tokarev in 2014:
this is file mjt-set-oem-in-rsdt-like-slic.diff
from https://packages.debian.org/jessie/qemu-kvm
This patch cleanly applies also to qemu-kvm-ev-2.1.2-23.el7_1.3.1
See mjt-set-oem-in-rsdt-like-slic.diff
and qemu-kvm.spec.patch in attach for details.
After executing rpmbuild -ba qemu-kvm.spec
you can place new qemu-kvm binaries into
/srv/download/centos/7/privat/x86_64/Packages
create local repo and use it for upgrading rpm packages,
for example, see privat.repo and privat-createrepo-7-x86_64
in attach.
==============================================================
Better if this workaround of Windows bug will be included
into RHEL/CentOS ovirt repo binaries, and this will allow
to anybody easy migrate Windows from hardware nodes
to VMs and easy run CentOS/RHEL at hardware nodes.
P.S.
After patching qemu-kvm - option
acpitable works without any bugs:
# man qemu-kvm
-acpitable [sig=str][...]
If a SLIC table is supplied to qemu,
then the oem_id from the SLIC table
will be copied into the RSDT table
(this is a Debian addition).
----- Original Message -----
Is it possible to use binary packages build from
http://resources.ovirt.org/pub/ovirt-3.5/rpm/el7/SRPMS/qemu-kvm-ev-2.1.2-23.el7_1.3.1.src.rpm
with plain CentOS 7.1 and use all other packages from CentOS
(libvirt, virt-manager, etc)
Is it have reasons, if I not use live migrations and qcow2 snapshots?
(instead use zfs, zvols and zfs snapshots for VM disks online backups)
Is using qemu-kvm-ev with CentOS 7.1 have any disadvantages?

commit 4933716beef26b353a1c374d6d8e6dd2e09333af
Author: Michael Tokarev <mjt@xxxxxxxxxx>

Subject: copy OEM ACPI parameters from SLIC table to RSDT
When building RSDT table, pick OEM ID fields from uer-supplied SLIC
table instead of using hard-coded QEMU defaults. This way, say,
OEM version of Windows7 can be run inside qemu using the same OEM
activation as on bare metal, by pointing at system firmware:
-acpitable file=/sys/firmware/acpi/tables/SLIC
Windows7 requires that OEM ID in RSDT matches those in SLIC to
consider SLIC to be valid.
This is somewhat hackish approach, but it works fairy well in
practice.
