Hi all,
I'm using qga to send `route -n` and `ping` command to guest. But I found
SOMETIMES, the second `ping` command's result is the same as `route -n`
command.
So I guess is there some cache mechanism of qga command result? So when I
send the second command, and receive from qga socket, I receive the result
of first command.
Or is this bug happened because of I use async mechanism of python code to
operate qga socket?
This is the python code I use to operate on this qga socket:
try:
> sock=socket(AF_UNIX, SOCK_STREAM)
> sock.settimeout(20)
> sock.connect(vm_qga_sockpath)
> sock.send(cmd)
> while True:
> res = sock.recv(1024)
> if len(res):
> break
> except Exception as e:
> res = -1
> finally:
> sock.settimeout(None)
> sock.close()
