I'm working with the Libvirt Python bindings and have discovered the
following:
If I run virConnect.listDomainsID() locally I get a list of valid IDs.
For example:
>>> import libvirt
>>> conn = libvirt.open('xen://')
>>> conn.listDomainsID()
[0, 35, 36, 37, 38, 39, 40, 61]
If I run the exact same thing remotely I get a list including numerous
invalid IDs. This example shows the same host as shown above, about 20
seconds earlier (everything essentially identical):
>>> import libvirt
>>> conn = libvirt.open('xen+tls://xxxx.xxxxx')
>>> conn.listDomainsID()
[0, 35, 36, 37, 38, 39, 40, 51, 52, 53, 54, 60, 61]
IDs 51, 52, 53, 54 and 60 are invalid.
I first noticed this problem working with libvirt 0.6.0 on the client
and 0.6.2 on the server, and noticed that with those versions the
problem also occurred with virsh.
Locally(0.6.0):
local ~ # virsh list
Id Name State
----------------------------------
0 Domain-0 running
35 xxxxxxx idle
36 xxxxx idle
37 xxxxxx idle
38 xxxxxxxxx idle
39 xxxxxx idle
40 xxxxx idle
61 xxxxxxxxxx idle
Whereas remotely(0.6.0):
remote # virsh -c xen+tls://xxxxx.xxxxx list
Id Name State
----------------------------------
0 Domain-0 running
35 xxxxxxx idle
36 xxxxx idle
37 xxxxxx idle
38 xxxxxxxxx idle
39 xxxxxx idle
40 xxxxx idle

However with virsh 0.6.2 on the client this appears to be fixed.
