Hi,
Quick question, since I can't get to the qemu monitor anymore, how do I hot add a usb device (smartphone)?
Is it possible to do through virsh?
Sure:
- Use 'lsusb' to determine the bus and device. Example listing looks like:
Bus 001 Device 006: ID 0781:5151 SanDisk Corp. Cruzer Micro 256/512MB Flash Drive
- Put hostdev xml in a file:
cat << __EOF__ > usb.xml <hostdev mode='subsystem' type='usb'> <source> <address bus='1' device='6'/> </source> </hostdev> __EOF__
- Run 'virsh attach-device {VMNAME} usb.xml' on a running VM.
Hope that helps, Cole
