Hi all,
I start VM using command like this:
-chardev socket,path=/home/gangyewei-3/kvm/qga.sock,server,nowait,id=qga0
> -device virtio-serial -device
> virtserialport,chardev=qga0,name=org.qemu.guest_agent.0
But When I use socat to send command (
https://wiki.qemu.org/Features/GuestAgent), it blocked. Why and how to fix
this? Thank you~

Hi Sam,
>From the command line I assume that you are running CentOS-7-x86_64, did
you install the guest agent on the VM? Can you see that it is running?
What do you mean by blocked?
