Re: [Qemu-discuss] Why I got "timeout" while using qga socket to connect VM?

[Sam]

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~

whole command is :

/usr/local/kvm/bin/qemu-system-x86_64 -smp 4 -m 4096 -enable-kvm
> /home/gangyewei-3/kvm/centos6.6_2.img -cdrom 
> /home/gangyewei-3/kvm/CentOS-7-x86_64-DVD-1503-01.iso
