Description:

qemu based VM's (Win10, Centos7) hang up when shut down the vm.
this only happens when macvtab in bridge mode (other modes not testet) is selected and only if i use virtio driver.
e1000 and rtl8139 works whithout this problem.

I used the setup: macvtab in bridge mode with virtio, round about 2 weeks in past it starts to brick when vm is shutdown. (freezing process)
And only when shutdown - then the system has a hanging vm, i was unable to kill this process even a kill -9 dont work.
this result in problem while systemd try to shutdown the vm when i shutdown my laptop, end up with pressing the power button until power off...

I used virt-manager for manage my vm's
