Then you should definitely submit a bug with redhat about this, seems like a serious one.<br>

<br>
As I can see - <a href="http://bugzilla.redhat.com" rel="noreferrer" target="_blank">bugzilla.redhat.com</a> for oVirt Product<br>
does not contain qemu-kvm-ev Component at all - looks<br>

But I can't find how to report this bugzilla misconfiguration,<br>

qemu-kvm-rhev from Red Hat Enterprise Virtualization Manager Product.<br>

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

Is it possible to use binary packages build from<br>

Is it have reasons, if I not use live migrations and qcow2 snapshots?<br>
