Many thanks for the quick reply, and for mentioning the forum... I have to
apologize for not replying sooner - a combination of the weekend and keeping
myself busy with further testing and experimentation.
While I had browsed the mailing list archives & wiki primarily, somehow I
missed the forum completely. It looks like I could have saved some debugging
however, as after the patch, the storage functionality works fine.
Long story short: all is now working. But not to spoil everything, there are
more details below, plus one question and a minor bug report at the end.

Ubuntu 8.10 comes with open-iscsi 2.0.865 (where 'iscsiadm -m session'
doesn't work, as hinted to in their release notes), while my backport of
Ubuntu Jaunty's open-iscsi package is 2.0.870 (discussion here:

It happened if I was on the data center summary, group summary, or
individual server; if I allowed the initial summary to fully display or not.
I've "abandoned" my vmconsole machine for now, and installed convirt on my
laptop (also Ubuntu 8.10), where I installed convirt from package (0.8.?)
and then upgraded to 0.9.6 (src and storage folders from tar distribution,
replaced startup script) - somewhat sloppy, but it resolved the dependencies
quickly & works (help>about confirms the correct version).
I delayed pataching paramiko innitially, connected to the servers, deployed
a virtual machine based on the linux cd install image (CD is iso on nfs; hda
is an iscsi storage target), and successfully installed ubuntu using
convirt's console function. Close & start convirt, look at overall summary,
server group summary or individual summary - no freeze, although from time
to time it hangs for a few seconds. I then patched paramiko, started convirt
and it froze shortly after. Returned the original, things worked fine for a
bit, up until vmhost2 got "sticky" and froze convirt (something was up with
/proc). I put in place the patched version, and with the one server - no

No. That was also part of my problems -- and I assume that whatever was not
configured also the cause of the live migratio. However, now that I have
the environment working, I can edit without problems and live migration
worked (testvm1 from vmhost1 to vmhost2 and back).

Stopping the VM made it disappear. However, this is no longer a problem --
so surely some problem in my setup was at fault.

Many thanks for the help and my apologies for bringing unconstructive
issues! At the moment, things are working well.
One question: the "Storage" summary displays as 0.00 / 16.00 GB, while
Storage is two 8GB iSCSI targets, one of which is assigned to the VM. The
question goes: how is the storage usage calculated?
As well, one bug (more esthetical than functional) to comment on: "Data
Center" summary view shows "VM Summary" as -1/1/0/0 for the "Servers" group,
while on the "Servers" group, and the individual server's, it is displayed
I'll have to see if I can replicate the problem after my next step (which is
cleaning up the systems and starting fresh to make sure all is stable)
Hope to bring more positive comments in the future!
