when i followed the url: 
http://www.wongkey.com/archives/ubuntu-11-10-install-xen
i got the same problem. but in /etc/xen/xend-config.sxp file, change this line
# (xen-unix-server no) 
into
(xen-unix-server yes) 
and it works. pay attention to '#' and the word 'yes'.

 virt-manager has the username root as username hardcoded in.
Although you can specify a different user name, it will not work.

Using u...@host works on virt-manager for karmic and lucid. Tested
today.

[Bug 198957] Re: virt-manager needs libvirt-bin, but is not marked as required

2009-01-14 Thread Daniel Kulesz
Actually there are two problems I see there:

(1) You are trying to connect to the Host with xen+ssh. This will not
work on Ubuntu until you set the root password (which is ugly of
course), since virt-manager has the username root as username
hardcoded in. Although you can specify a different user name, it will
not work. The manual also outlines this briefly:

http://virt-manager.et.redhat.com/page/RemoteSSH

And there is also a bug report available on this issue:

https://bugzilla.redhat.com/show_bug.cgi?id=470416

To verify it's not a virt-manager problem, I would suggest to try
connecting with virsh first. (i.e. virsh -c xen+ssh://hostname/system)

(2) I am getting the following error as well, when trying to connect
using TLS/SSL to a 8.04 box where Xen is obviously working:

libvirtError: virConnectOpenReadOnly() failed
remoteDispatchClientRequest: internal error: library function returned
error but did not set virterror

This error message is not helpful at all. Any ideas?

Nick, I am sorry if I confused things a bit, I understand now what you
mean. Our bugs are not related, because we don't complain about missing
libvirt-packages during install but rather the non-working of virt-
manager *inspite* of having them installed, right?

I thus opened a new bug as you requested here:

Kind regards and thanks for all the help!

Just a quick note, but I encountered the same error while trying to
explore XEN/KVM/QEMU.

Not sure what I've got to do to get things rolling here, but it clearly
isn't working.  I also don't have KVM as an option in `virt-
manager`..

Unrelated and correct me if I'm wrong:  I am foreseeing some real
confusion and chaos between all the virtualization options going around
these days.  XEN for running VMs, KVM for developing on them, and QEMU
as some kind of neglected sibling.

The software packages for sure need some structuring love and I think
some wiki documents are due.

Sorry, Soren, but what Nicolas is reporting _is_ this same bug, which
has _not_ been fixed. I was just bitten by it myself. I see two
possible, non-mutually-exclusive solutions:

1) Make libvirt-bin a Recommended package of virt-manager.
2) Make both libvirt-bin and virt-manager required dependencies of the 
ubuntu-desktop metapackage.

The second solution is the sledgehammer approach, but may prove
beneficial in the long run. In any case, I strongly recommend the first
solution above.

 I understand that its not a library package, thats not the point.

When you start your initial bug report saying [...] so virt-manager
gets installed without some needed library files, then I think it's
quite relevant.

 The point is that in a default installation a user will always get
 this error message when trying to connect to the local machine (which
 is the default connection offered at startup). I would suggest that
 connecting to a remote libvirtd is not the first option most people
 would be trying.

That might be true, but I'm not convinced that virt-manager depending on
libvirt-bin is the correct solution to this that problem. (Referring
to a simple fact (that most people will not attempt to connect to a
remote libvirtd as the first thing) as a problem seems a bit off to me,
hence the quotation marks)

 Anyone trying to use Virtmanager for the first time, with default
 options, will always get this error and won't be able to do anything
 until libvirtd is running (which is contained in the libvirt-bin
 package, not installed by default).

Erm, no. Anyone trying to use virt-manager for the first time, with
default options, will get an entirely *different* error, namely a
failure to connect to Xen.

 No one should have to look at that error message and work out for
 themselves what has to be done to get thing working when the default
 install of one small package could resolve the problem or perhaps a
 change to the user interface to make it explicit what the dependencies
 are.

The size of the package is not really all that interesting. There are
quite a few libraries of 100k in size, but I'm not going to add those
as a dependency either :)

Let's all just take a step back and look at the *problem*, rather than
what any of us guesses it the right solution. That tends to lead to the
correctest solutions.

Initial analysis: There are many Ubuntu users who'd like to try out the
new, cool virtualisation stuff. These users will often just have a
single machine for this and thus will want to have the daemon and the
management tools running on the same system. The essential packages
involved are: virt-manager, kvm, libvirt-bin. We'll refer to a system
with those packages installed as a useful system.

Good so far?

Additional information: libvirt-bin is useful on its own.  virt-manager
is useful on its own.  kvm is useful on its own.

Problem: Getting from a clean install to a useful system is proving
difficult, inconvenient, or unobvious.

There are a number of different ways to turn a given system into a
useful system. Dependencies between the three relevant packages is
wrong, due to the fact that each package is useful on its own. 

A new metapackage depending on all three packages is equally unobvious
(undiscoverable to the innocent bystander).

A useful notice when failing to connect to libvirtd saying that
Connection to local libvirtd failed. Is libvirt-bin installed? or
something to that effect is simple to implement, to the point, and
doesn't introduce wrong dependencies. Sounds like a plan?

Sorry, my mistake. That used to be the case, but I seem to have fixed
that already. You don't get an error until you actively try to connect
to the hypervisor, though.

Yes I did make refer to a library at first, in my haste to try out the
manager I didn't look to see what was in the package, just assumed most
anything beginning with lib had to do with a library.

A useful notice when failing to connect to libvirtd saying that
Connection to local libvirtd failed. Is libvirt-bin installed? or
something to that effect is simple to implement, to the point, and

That should make it clear enough, good. I recall some applications even
offering to initiate installing a package but I guess that would be more
involved. Thanks for explaining the difficulties of package management,
almost sounds like the dining philosopher problem.

Virt-manager works pretty well otherwise with KVM, have not tried Xen
yet.

2008-03-06 Thread [EMAIL PROTECTED]
OK,
I removed the libvirt-bin package and the error appeared again after starting 
virtual manager and trying to connect.
An error window entitled Virtual Machine Manager Connection Failure pops up 
with the following text:
--
Verify that:
 - The 'libvirtd' daemon has been started

Unable to open connection to hypervisor URI 'qemu:///session':
class 'libvirt.libvirtError' virConnectOpenReadOnly() failed

  File /usr/lib/python2.5/site-packages/libvirt.py, line 144, in openReadOnly
if ret is None:raise libvirtError('virConnectOpenReadOnly() failed')
libvirtError: virConnectOpenReadOnly() failed

Since libvirtd is in in the libvirt-bin I would think it should be required by 
virt-manager or one of its dependencies like python-libvirt (if I understand 
dependencies well enough).

Also, I notice that the libvirt0 package description has a typo too:
library for interfacing with differeny virtualization systems

 entitled Virtual Machine Manager Connection Failure pops up with the
 following text:
 --
 Verify that: - The 'libvirtd' daemon has been started
 
 Unable to open connection to hypervisor URI 'qemu:///session':
 class 'libvirt.libvirtError' virConnectOpenReadOnly() failed
 Traceback (most recent call last):
   File /usr/share/virt-manager/virtManager/connection.py, line 306, in 
 _open_thread
 self.vmm = libvirt.openReadOnly(self.uri)
   File /usr/lib/python2.5/site-packages/libvirt.py, line 144, in 
 openReadOnly
 if ret is None:raise libvirtError('virConnectOpenReadOnly() failed')
 libvirtError: virConnectOpenReadOnly() failed
 

The error message even explicitly tells you that you should check if
libvirtd is running. It's not a library that's missing, you're just
trying to connect to a local libvirtd instance, but you have no such
thing (as you don't have libvirtd running). virt-manager doesn't *need*
a local libvirtd instance, as it can be used to manage remote ones
instead.

 Also, I notice that the libvirt0 package description has a typo too:
 library for interfacing with differeny virtualization systems

Ah, thanks. I'll fix that.

virt-manager needs libvirt-bin, but is not marked as required
