libvirt users - Aug 2015 - When adding a channel device, we need a shutdown

Hi,

It looks like , when adding a channel device, that   the Guest must be powered
off / on to be able to detect
the new device . ( simple reboot isn't not enough)

Is there any way to avoid this power_cycle  ?

Thx.

Yes, you can hotplug the device: virsh attach-device --live ...
It's supposed to be implemented since the 1.1.1 release.

Hi,

"Yes, you can hotplug the device: virsh attach-device --live ...

Does it mean that a virsh attach-device --config    (AFAIK ,  taken in account
at next guest reboot) should work
by using release to 1.1.1 ?

Thx.
