Hello All,
I work for a educational institution, and we currently use oVirt in our
datacenter. We are on the latest stable build of oVirt 3.4.4. Most of our
hypervisors run CentOS 6.5; however, we have recently been asked if we
could assign virtual hypervisors (Server 2012 R2) to some of our classes
for learning purposes. I have been doing some research and found that I
needed atleast kernel 3.10; therefore, I took one hypervisors and converted
it to CentOS 7 fully patched. I also installed the nestedvt hook as
described here
<
http://community.redhat.com/blog/2013/08/testing-ovirt-3-3-with-nested-kv...;.
I am all researched/googled out, and I am having no luck. After I do a
typical install of Server 2012 R2 it will not let me install the Hyper-V
role. I quote "Hyper-V cannot be installed: A hypervisor is already
running".
When I run the command cat /sys/module/kvm_intel/parameters/nested it comes
back with a "Y". If I look in the host hooks it shows the nestedvt and
macspoof. The VM has a custom property of macspoof = true.
Did I miss something? Is this possible? Has anyone done this before?
I guess you need the cpu param
"hv_relaxed" there is a BZ open on it, see
this blog for all cpu flags:
http://blog.wikichoon.com/2014/07/enabling-hyper-v-enlightenments-with-kv...
-cpu ...,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time
there are plenty of bugs / improvements open, here is the list:
https://bugzilla.redhat.com/buglist.cgi?quicksearch=hv_relaxed&list_i...
I don't know if this really works yet, the performance might be very
poor, even under older vmware stuff it's poor, according to vmware:

Thank you in advance for all you do. Your work on this project has
helped
our community college greatly and our student even more. Because of this
project we have be able to give students virtual resources to complete
their labs from anywhere at anytime.
