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

No go for me, maybe I'm running the wrong version of virsh?

What am I doing wrong?

You need libvirt version 0.5.0 or later.

Ok, Thanks.
I'm using Ubuntu so I guess I will have to compile it myself.
Thanks again,
