Hi Michal,

Well I have created my little python/libivrt app to manage my virtual
machines. I am using python socket to check libivrt port availability, and
the error End of file while reading data: Input/output error* only happens
whenever that python socket script is trigger.
Here is the script of python socket
import libvirt, socket, sys
hostname='kvm09'
port = 16509
try:
socket_host = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socket_host.settimeout(1)
socket_host.connect((hostname, port))
socket_host.close()
print 'true'
except Exception as err:
print err
Ah, I haven't expected this. Of course your are seeing the error
message. Libvirt has its own protocol on the top of TCP and since you
are connecting and dying immediately - without sending any valid libvirt
packet, the daemon logs an error. This is perfectly expected.
Also, this is *not* how you connect to libvirt. You want to open a
libvirt connection:
conn = libvirt.open(uri)
dom = conn.lookupByName(name)
...

Michal,
my expectation is that virsh is using a libvirt connection.
Anyway I am getting the error whenever I use virsh start, virsh destroy
or virsh shutdown on a domain, e.g.

Would that also be covered under "This is perfectly expected."?
