Greetings,
I'm executing an external script when the qemu hook is called with start or release, the script is rather simple, upon start it iterates over the output of lsusb -t and for each device, it looks if it should be added to the vm we started, if so, it attaches it to the vm as follows:
virsh --connect qemu:///system "${cmd}" "${domain}" /dev/stdin << END
<hostdev mode='subsystem' type='usb'>
<source>
<address bus='${busnum}' device='${devnum}' />
</source>
</hostdev>
END
where cmd is attach-device, domain is the vm's name, busnum and devnum come from the output of the lsusb -t.
my issue is that upon the first attach attempt, the cmd hangs, I need to kill it and after than I cannot preform any virsh cmd, I must restart the host.
if I try to execute the same cmd after the vm is up, it works great.
why the attach process gets stuck? do I need to execute it under different stage?
thanks,
Dagg.
