Description Nisim Simsolo 2016-02-10 09:55:19 UTC

qemu-kvm-rhev-2.3.0-31.el7_2.4.ppc64le
libvirt-client-1.2.17-13.el7.ppc64le
vdsm-4.17.19-0.el7ev.noarch

How reproducible:
100%

Steps to Reproduce:
1. Add PPC host to engine environment.
2. Try to attach PCI device to VM.
3. Observe webadmin hosts tab ==> general.

Verification scenarion:
1. Attach host PCI device to VM and run VM.
2. Verify device attached and appears in webadmin --> virtual machines tab --> VM --> host devices tab.
3. Open VM console and verify PCI device is attached (using lspci command).
4. Power off VM abd Verify powering off VM does not affect host functionality.
5. Run steps 1-4 again.
