[libvirt] Python listDefinedDomains broken?
Hi everyone,
please, don't roast me if I'm asking stupid things or fail to provide
info, since I'm a freshman, using libvirt.
I have two servers, both running the following versions:
Compiled against library: libvirt 1.3.1
Using library: libvirt 1.3.1
Using API: QEMU 1.3.1
Running hypervisor: QEMU 0.14.0
I'm trying to create a Python program, which gets a list of all defined
domains for each host and give a list for domains only defined on one of
these hosts. This Python script is running on a third host (my
workstation), using these versions:
Python: 3.5.1
libvirt-python: 1.3.1
When I'm running virsh on my workstation (version 1.3.1), like this:
virsh -c
"qemu+ssh://root@host1/system?keyfile=/home/user/.ssh/id_rsa_libvirt"
--readonly list --all
Then a domain named "winxp_ausgeschaltet" is within that list:
Id Name State
----------------------------------------------------
...
- winxp_ausgeschaltet shut off
When I do the same for the second host, it is also in that list:
Id Name State
----------------------------------------------------
...
7 winxp_ausgeschaltet running
When I do the following in Python, this domain is listed for the first
host (where it's state is "shut off"), but not for the second one:
import libvirt
import sys
class kvmhost:
def __init__(self, host, keyfile):
self.conn = self.connect_kvm(host, keyfile)
self.doms = sorted(self.get_doms())
def connect_kvm(self, host, keyfile):
try:
conn = libvirt.openReadOnly('qemu+ssh://root@' + host +
'/system?keyfile=' + keyfile)
except libvirt.libvirtError as lve:
print('Error: ' + str(lve))
sys.exit(1)
return conn
def get_doms(self):
try:
alldoms = self.conn.listDefinedDomains()
except libvirt.libvirtError as lve:
print('Error: ' + str(lve))
self.conn.close()
sys.exit(1)
return alldoms
host1 = kvmhost('host1', '/path/to/ssh_keyfile')
host2 = kvmhost('host2', '/path/to/ssh_keyfile')
print(host1.doms)
print(host2.doms)
What am I doing wrong here or: is there a missbehavior in libvirt or the
python module?
Using listAllDomains instead of listDefinedDomains gives:
libvirt: Remote Driver error : unknown procedure: 273
What is the difference between listAllDomains and listDefinedDomains at all?
Thanks for your help.
