Comment 17 for bug 1716028

We had a discussion today on how to workaround if you drive qmeu via libvirt.
While discussions often and up at the correctness of such setups they exists, I think it is worth to document until libvirt supports that officially.

TL:DR:
- no native libvirt feature yet
- discussions if <shareable/> should set it
- workaround available via cmdline

Details on the workaround:
- To use the workaround you have to check your log usually in /var/log/libvirt/qemu/<guestname>.log
- Get the id of the device that matters to you
- then use [1] to tweak qemu cmdline
- example is from [2] to [3]
