Bug 1430273

Description of problem:
When installing VM using virt-install, installation fails with the following error:
ERROR    internal error: unable to execute QEMU command 'query-iothreads': The command query-iothreads has not been found


Version-Release number of selected component (if applicable):
virt-install-1.4.0-2.el7.noarch
virt-manager-1.4.0-2.el7
qemu-kvm-1.5.3-132.el7.x86_64
qemu-img-1.5.3-132.el7.x86_64
libvirt-3.1.0-1.el7.x86_64
libvirt-client-3.1.0-1.el7.x86_64


How reproducible:
Reproduced with kickstart installation and also when importing an empty qcow2 image.


Steps to Reproduce:
1. Create an empty image:
# export IMAGE=/var/lib/libvirt/images/test.qcow2
# qemu-img create -f qcow2 $IMAGE 5M

2. Run virt-install:
# virt-install --hvm --connect qemu:///system --name=test --os-type linux --os-variant=rhel7 --disk path=$IMAGE,device=disk,format=qcow2 --graphics none --ram 128 --vcpus=1 --network network=default --import

Starting install...

Domain installation does not appear to have been successful.
If it was, you can restart your domain by running:
  virsh --connect qemu:///system start test
otherwise, please restart your installation.
