Description Milan Zamazal 2018-09-14 18:59:17 UTC

Vdsm should enable dynamic_ownership libvirt option and pass ownership and permission management of host devices to libvirt. That not only avoids the need to handle ownership and permissions of host devices in Vdsm, but it's also necessary for features such as Q35 support or secure boot support.

Comment 1 Milan Zamazal 2018-09-27 14:51:09 UTC

Regarding verification, it's important to test that:

- snapshots with memory work with all the supported storage kinds (NFS, iSCSI, GlusterFS, ...);
- CD-ROM works, both empty and with a media attached;
- disk hot plugs work, including block storage;
- passthrough host devices can be successfully attached to a VM: SCSI, USB, PCI (IOMMU);
- mediated devices can be attached;
- /dev/hwrng can be attached.

Comment 2 Nisim Simsolo 2018-11-08 12:39:57 UTC

Verified upstream: 
ovirt-engine-4.3.0-0.0.master.20181101091940.git61310aa.el7
vdsm-4.30.1-34.gitad59c72.el7.x86_64

qemu-kvm-common-ev-2.10.0-21.el7_5.7.1.x86_64
sanlock-3.6.0-1.el7.x86_64

Verification scenario:
Manual tests:
1. USB passthrough
2. CDROM attached to VM with and without media
3. Disk hotplug (NFS and iSCSI)
4. VFIO
5. mdev, also with multiple devices on the same VM
6. Intel GVTg
7. add/remove NFS storage also NFSv4.2 - V
8. add/remove iSCSI storage - V
9. HWRNG
10. v2v from Xen and VMware
11. Import from KVM
12. VM sanity (snapshots, templates, clone etc.)

Automation tests:
No related issues observed in automation results analysis.
