I launch a VM which use vhost-user netdevice as follows.When detach the netdevice in qemu monitor, the chardevice which used by the netdevice also should be deatched.The netdevice can be detached sucessfully.But the chardevice failed when it was being detaching.
Full command line :
qemu-system-x86_64 \
-cpu host -boot c -hda /home/lining/ubuntu_12_04.img -snapshot -m 2048 -smp 2 \

The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience.
