Nope, we're using CentOS 7 with python 2.7.
And the script itself seems to work, it just gets stuck when trying to
connect to the socket ( s.connect(..) )

If you're using CentOS6 based KVM hosts, can you make sure you've
argparse installed? The patchviasocket script was changed from perl
based implementation to a Python based installation that uses a
library that is not available with Python 2.6.
Try this on kvm host(s):
sudo pip install --upgrade argparse
See, if this fixes the issue.

Hi.
We have made an upgrade to 4.9.
Custom build packages with our own patches, which in my mind (i'm the
only one patching those) should not affect the issue i'll describe.
I'm not sure whether we didn't notice it before, or it's actually
related to something in 4.9
Basically our system vm's were unable to be patched via the qemu
socket. The script simply error'ed out with a timeout while trying to
push the data to the socket.
Executing it manually (with cmd line from the logs) resulted the same.
I even tried the old perl variant, which also had same result.
So finally we found out that this issue happens only on our HVs which
run qemu 2.3.0, from the centos 7 special interest virtualization
repo. Other ones that run qemu 1.5, from official repos, can patch the
system vms fine.
So i'm wondering if anyone tested 4.9 with kvm with qemu >= 2.x? Maybe
it something else special in our setup. e.g. we're running the HVs
from a preconfigured netboot image (pxe), but all of them, including
those with qemu 1.5, so i have no idea.
