[Ci-users] Problems in cloud-sig jobs after enabling 7.1611

Hi,

After getting new 7.3 packages in the jobs running in cloud-sig we
have started getting error "qemu-kvm: CPU feature arat not found"
while launching VMs in intel hardware.

According to information found in
https://bugzilla.redhat.com/show_bug.cgi?id=1371617, the root cause
for this is using libvirt from 7.3 with
qemu-kvm-ev-2.3.0 from virt-sig.

As there is not qemu-kvm-ev-2.6.0 available yet, this is making our
jobs to fail whenever they run in any intel server and the known
workaround is not so easy to implement.

Is there anyway we could disable cr repo at kickstart time for
specific jobs?, i think it's risky to enable in every job when there
are dependencies with packages from SIGs which are not included in cr
repo.

Best regards,

Alfredo
