[needs-packaging] virt-manager

Ubuntu's libvirt is out of date. Here is an updated one.

Original source is at http://libvirt.org/sources/libvirt-0.2.2.tar.gz

Binary packages is attached

Virtinst is a dependency of virt-manager. Original source is at http://virt-manager.et.redhat.com/download/sources/virtinst/virtinst-0.103.0.tar.gz.

Virtinst binary attached.

Virt-manager original source is at http://virt-manager.et.redhat.com/download/sources/virt-manager/virt-manager-0.4.0.tar.gz

virt-manager binary attached

Verifying that these packages install and work correctly, and appear to have proper dependencies set as well. Thank you!

Found a bug in the virt-manager package, actually. It's given as architecture "all" but it includes .so files. In particular, it doesn't run on my AMD64 box:

Traceback (most recent call last):
  File "/usr/share/virt-manager/virt-manager.py", line 105, in <module>
    from virtManager.engine import vmmEngine
  File "/usr/share/virt-manager/virtManager/engine.py", line 31, in <module>
    from virtManager.manager import vmmManager
  File "/usr/share/virt-manager/virtManager/manager.py", line 26, in <module>
    import sparkline
ImportError: /usr/lib/virt-manager/sparkline.so: wrong ELF class: ELFCLASS32

Either sparkline needs to be split out, or the package has to be made architecture-dependent.

I was able to install Marcelo Boveto Shima's virt-manager_0.4.0-0ubuntu1_all.deb [ https://bugs.launchpad.net/ubuntu/+bug/116897/comments/13 ] using "sudo dpkg -i" but when I ran it I hit an error. The .deb needs to require python-libvirt, or whatever may be necessary. Error is below:

---

After resolving this issue, I am hitting the error in the previous comment; I am attempting to run this on an up-to-date Feisty. Is there any chance we could get a package built for amd64? Thanks!

I have installed virt-manager with the package virt-manager_0.4.0-0ubuntu1_all.deb on my Kubuntu 7.04.
The module named gtkvnc is missing but I was unable to find it in the Kubuntu's packages.

I am also interested in this for KVM support. Is the package still broken for amd64? I run 64-bits...

I just didn't find one in the bug when I looked. I assume you could build it
yourself... not having this issue anymore as I'm using Fedora. :p You could
probably just install the one from Fedora.

I created an PPA archive with virt-manager, amd64 binary too.
I didn't try it on ubuntu 64.
To make kvm work is necessary to create the directory /var/run/libvirt and run libvirtd as root.

I don't have much time now to work on this package, but please report the bugs.

repos:
deb http://ppa.launchpad.net/marceloshima/ubuntu/ feisty main universe

I installed marceloshimas Packages, and wrote my comments on http://inhalt.serviert.de/wissen/gpl/xen/xen-installation-auf-ubuntu-7.10-gutsy-gibbon-amd64-virt-manager

There is a dependency missing, so you cannot start virt-manager or virt-install - you need to perform an aptitude install python-libxml2.

But then you got another error:

$ virt-install

Ok. I found why virt-install or virt-manager couldnt connect. My /etc/xen/xend-config.sxp lacked of the line

(xend-unix-server yes)

Now I can connect, but networking doesn't

$ virt-install
libvir: Remote error : No such file or directory
libvir: warning : Failed to find the network: Is the daemon running ?

Do you have any hints ?

Thanks for your reply in advance.

Thomas.

Try to install bridge-utils and dnsmasq

What version of libvirt, virt-inst and virt-manager are you using?
The one from my ppa repository?

The packages got into debian last week and the maintainer made some changes.
I will update on my ppa tomorrow or after.

Marcelo.

Just remembered that I've created some dirs. Try to create the directories /var/lib/xen/images and /var/lib/xen/dump.
I will update the package soon.

Marcelo, I created these directories and now the paravirtualized VM is created (but I cannot see any Virtual Networks, but I can take a shared virtual device (peth0)).

When trying to finish virtmanager thows:

Unable to complete install '<class 'libvirt.libvirtError'> virDomainCreateLinux() failed POST operation failed: (xend.err 'Device 0 (vif) could not be connected. Hotplug scripts not working.')

I got the same error when trying to create a fully virtualized guest. (xend.log)

virsh is connecting to qemu/kvm by default.

Good. Working now (with errors)

I added the above mentioned repository a while ago, but recently there have been a few virt-manager/libvirt updates. I think these may have been some upstream packages. Anyway, these packages dont seem to work too well as /var/run/libvirt doesnt exist. I have made the following change to the init file to get it working.

Also... with the updated packages, when you restart or stop libvirt-bin, the bridge is not taken down. Not sure where that is run.

This has been fixed in debian and Soren told me he was working on a merge.
He just uploaded.
So I just backported the new package.

Sorry, can't reproduce this. Do you have more info about this?
I will figure out how to used the new libvirt0-dbg. This should help to
debug it.

If libvirt-bin is started, then you have the bridge interface:

$ ifconfig virbr0
virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00
          inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0

Stop it:

~$ sudo /etc/init.d/libvirt-bin stop
 * Stopping libvirt management daemon libvirtd [
OK ]

Problem, its still up:

$ ifconfig virbr0
virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00
          inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0

Try and start it:

$ sudo /etc/init.d/libvirt-bin start

libvirtd libvir: QEMU error : cannot create

Ok, this happened some time ago to me when libvirtd sigfaulted, but the
bridge was
up and didn't went down. brctl didn't help me so to remove this bridge the
only way
I found was to reboot.

Try to debug it by:
disabling auto start on /etc/default/libvirt
reboot

Then
$ sudo libvirtd -v

This should start libvirtd on verbose mode.
When you use virt-manager the console with libvirtd should print
informations
about some operations.

Post the results here. Try to use the new package, it is built already.

Testing ppa new packages, I got the following error:

syslog:
Dec 21 14:55:32 tirisrv01 kernel: [143348.239524] virbr0: starting userspace STP failed, staring kernel STP

stderr:

Failed to autostart network 'default': failed to add iptables rule to allow DHCP requests from 'virbr0' : Invalid argument

What's now wrong ?

brctl show shows:
brctl show
bridge name bridge id STP enabled interfaces
xenbr0 8000.feffffffffff no vif0.0
                                                        peth0

The new packages have fixed the bridge issue. I am able to stop, start and
restart libvirt-bin and there are no issues. Yeah!

Unfortunately, /var/run/libvirt is still not being created by the init
script. Would you mind getting my patch integrated or ensuring that the
sockets are created somewhere that exists? Attached is a diff of the latest
package's init script.

This seems to be xen related problem. The network on your virtual machine is
working fine?
Xen is not letting brctl put iptables rules.

Included with some changes. There were some places that were using
/var/run/$NAME.pid
We have to take a closer look because I think the pidfile is created by the
daemon itself not by start-stop-daemon.

Yes. I have played with this a little and it appears that libvirtd does not
work properly when you try and supply --pid-file <file> to it. Even if you
run it without start-stop-daemon, it never quite manages to start properly.
I think this must be a bug in libvirtd.

Since the --pid-file is an issue, I think it would be better to set the
variables as follows in the init script:

PIDDIR=/var/run/libvirt
PIDFILE=/var/run/$NAME.pid

rather than

PIDDIR=/var/run/libvirt
PIDFILE=$PIDDIR/$NAME.pid

Can you please check if /var/lib/libvirt is provided by the package? After
installing the latest version, I had to manually mkdir /var/lib/libvirt for
the dnsmasq dhcpd.leases file to be created.

P.S. I see that you have added /var/run/libvirt to the libvirt-bin package.
I am not sure this is a good idea as /var/run is mounted in memory on boot,
hence the need to mkdir $PIDDIR.

We now have a recent virt-manager on hardy. I'm closing this bug.
$ apt-cache madison virt-manager
virt-manager | 0.5.2-3ubuntu1 | http://eu.archive.ubuntu.com hardy/universe Packages
virt-manager | 0.5.2-3ubuntu1 | http://eu.archive.ubuntu.com hardy/universe Sources

And about this error?

$ sudo libvirtd -v
libvir: QEMU error : failed to set bridge STP to on
Failed to autostart network 'default': failed to set bridge STP to on
Shutting down on signal 2

It's missing some package?

It seems that the libvirt-bin package is not marked as required in the virt-manager package in Hardy Alpha5 so virt-manager gets installed without some needed library files.

Once I installed libvirt-bin, virt-manager worked fine.

Thanks for reporting this bug (bug #198957).
