Created attachment 1265313 [details] record Description of problem: [UI] - 'Pinned Host' not available/not visible under VMs > Host Devices > 'Add Host Devices'. I wasn't sure if it's an ui bug or virt bug so forgive me if i was wrong. 'Pinned Host' not visible in the drop down list and it's host devices. Version-Release number of selected component (if applicable): 4.2.0-0.0.master.20170321181523.gitd3665b3.el7.centos How reproducible: 100 Steps to Reproduce: 1. GO to VM > 'HOst Devices' sub tab > 'Add Device' > 'Pinned Host' Actual results: NO host in the drop down list. Host devices not available. Expected results: Pinned Host must be available and visible and all it's host devices.
It depends, we filter out all hosts which are not capable of passthrough. If you go to the host and run: ls /sys/kernel/iommu_groups ls /sys/class/iommu does this return something? If not, than it is correct it is not there.
On Previous versions all hosts were available on the list(and non of my hosts return anything). Is it a new behaviour?
yes, it is a new behavior: https://gerrit.ovirt.org/#/c/72789/ It allows you to select only hosts which are eligible for passthrough.
Ok, So why there is no tooltip or warning near the 'Pinned Host' filed letting the user/admin know that there is no available/ eligible host/s for passthorugh? Why i can press the drop down list if it's empty? It's a bit confusing.
ok, you are right. This dialog will be touched anyway soon (certainly in 4.2 timeframe) we can enhance this experience. Added a note to https://trello.com/c/ugvsP989/47-mdev-vgpu to track it.
