Fedora xen - Jun 2006 - Xen/libVirt GUI app: "Virtual Machine Manager"

I''m pleased to make available the code for an early *development
snapshot*
of a graphical application for managing virtual machines. This application
is using libvirt as its backend API for managing virtual machines, while
the user interface is built in Python and GTK/Glade. The application allows
monitoring of guest VM resource utilization / allocation. There are basic
controls for controlling the run state of guest. There is also a VNC client
widget (written in pure Python!) for displaying the virtual guest framebuffer
on fully-virt machines:

  http://people.redhat.com/berrange/virt-manager/index.html

This is a very early snapshot - lots of functionality isn''t hooked up
yet, the error handling is mostly not there, and there are certainly
plenty of bugs. It should none-the-less give a reasonable feel for the
kind of direction the application will evolve in. Furthermore the website
includes the UI mockups done by our user interaction designers to show
some of the ideas considered in ongoing development of the application. 

The RPMs linked to from the website should install on both Fedora Core 5[1] 
and Fedora Core 6 test1 [2]. The FAQ contains a list of explicit dependancies
which should facilitate people trying to get it running on non Fedora Linux
distros.

BTW, for those at the Red Hat Summit in Nashville a few weeks back, this is
the graphical app I talked about in my presentation on management tools
for virtualized system[3] & showed some demos of. At the time I was
calling it ''GNOME Virt Manager'', but is now renamed
''Virtual Machine Manager''
or ''virt-manager'' for the binary command / package name. 

Regards,
Dan.

[1] You''ll need libvirt-0.1.1 from updates-testing
[2] The plan is to get the RPMs into Fedora Extras in time for FC6

It installed ok from your repo, also upgraded to libvirt ok, booted 
2.6.17-1.2307_FC6xen, xend running, started your GUI from a tty

# virt-manager
dbus_bindings.DBusException Unable to determine the address of the 
message bus ( try ''man dbus-launch'' and ''man
dbus-daemon'' for help)
Could not connection to session bus, disabling DBus service

Naturally I have got dbus running, at this point I got the open 
connection dialog, and tried to connect to local xen host (with and 
without read only, but as root) after a delay the dialog closed, but 
this message is displayed if invoked from a tty

libvir: Xen Daemon error : could not connect to Xen Daemon
Unable to open connection to hypervisor URI ''xen''
libvirt.libvirtError virDomainLookupByID() failed

However I did look at the mockup design and the screenshots on your 
pages, and I *like* the look of what it intends to do :-)

  Hum, which versions of xen, kernel and libvirt are you using ?
It seems the xend daemon can''t be reached locally, which makes a number
of operations (like mapping between domain names and id) impossible.

xen
Arch   : i386
Version: 3.0.2
Release: 4

libvirt
Arch   : i386
Version: 0.1.0
Release: 1

kernel-xen
Arch   : i686
Version: 2.6.17
Release: 1.2307_FC6

I was going to say the only selinux messages I''ve been noticing on
FC6T1
so far have been related to ntpd and nfs, but on checking I notice the 
following

audit(1151652889.670:87): avc:  denied  { recv } for  saddr=127.0.0.1 
src=40682 daddr=127.0.0.1 dest=8000 netif=lo 
scontext=system_u:system_r:xend_t:s0 
tcontext=system_u:object_r:unlabeled_t:s0 tclass=packet

so I''ll reboot with enforcing=0 and try again ...

Thanks

  Very latest Xen hypervisor, you must use libvirt-0.1.1 and preferably
a very recent xen too > 3.0.2-6

  I don''t think it''s selinux related, but an ABI breakage at
the Xen
hypervisor level. Update xen and libvirt.

Turns out it was selinux, booting in permissive mode allowed VMM to start up

I''m still not up to speed on selinux policies, it it possible to set
one
that allows anything (or certain contexts) to make a TCP connection to 
xend, or would a specific one need to be added for VMM? What are the 
rules for modifying selinux policy for an Extra''s package?

hmm, I''ll swear I had seen the update to libvirt 0.1.1 get installed 
when I installed from the berrange repo, I didn''t read the 0.1.0 when I
pasted it above :-(

I''m on the latest that rawhide offers me

strange, a reboot with enforcing=0 did allow it to run, and I was seeing 
the avc errors from xend receiving packets.

my yum isn''t happy at the moment, caught between mirror updates I
think,
checksums don''t match, let me try a cleanall/makecache and see if 
anything newer show up for me, I''ve noticed xen kernels
haven''t been
pushed for the last couple of kernel builds ...

Yes, the build has broken with the high amount of change going into the
kernel right now

Hello Daniel,

If have running success virt-manager on my FC5 xenbox with all available
features.

FC5 has the stat of latest yum update''s from original repo
update.
>From development.repo "yum install libvirt-python"
Disable development repo.
Add berrange-fedora.repo and "yum install virt-manager"

If I use the binary virt-manager rpm from your repo, I can start
virt-manager and a can define local xen host to connect. After this I get
the virt-manager gui. Becose the gui has then no content.

If I get the virt-manager src.rpm from your repo and rebuild the binary.rpm
on my xen host, install them, virt-manager is running success.

And  I say to virt-manager: "Welcome in the virtual future"..:-)

Many thanks,
Thomas

I think the problem is that you took libvirt from the
''development''
repository which is basically FC6test1. For FC5 you  should use the
''updates-testing'' repository as per the instructions on the
download page:

yum --enablerepo=updates-testing install virt-manager

Regards,
Dan.

You are right.
virt-manager running well with libvirt-python from updates-testing.
