internal error Network 'default' is not active

[Sasa Paporovic]

I am on Ubuntu12.04 64bit updated to 14.4.2012

A parallel installation of virtualbox 4.1.12 makes the internal network for qemu-kvm accessed with virt-manager unusable.

A have to remark that there is no start of virtualbox from my side. It is just installed and blocks qemu-kvm from working completly.

Additional:

On openSUSE platform they could coexist in this just installed way. Sure both are not able to run in parallel, but parallel install is o.K

I got on guest(saved state) starting attemped:

Fehler beim Wiederherstellen der Domäne: internal error Network 'default' is not active.

The same with normal start of all guests.

[Sasa Paporovic (melchiaros)]

Also after a complete removing of virtualbox it keeps like descibed obove with the same stacktrace

[Sasa Paporovic (melchiaros)]

You may want to notify a other network issue virtualbox causes:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/981723

[Sasa Paporovic (melchiaros)]

May be that a give virtualbox to much wigth on this.

On creating a new guest I got on activating default network:

Virtuelles Netzwerk 'default' konnte nicht gestartet werden: internal error Child process (/usr/sbin/dnsmasq -u libvirt-dnsmasq --strict-order --bind-interfaces --pid-file=/var/run/libvirt/network/default.pid --conf-file= --except-interface lo --listen-address 192.168.122.1 --dhcp-range 192.168.122.2,192.168.122.254 --dhcp-leasefile=/var/lib/libvirt/dnsmasq/default.leases --dhcp-lease-max=253 --dhcp-no-override) status unexpected: exit status 2

I have messed arround with orchestra and misconfigured the dhcp configuration during this.

This seems to affect also qemu-kvm.

[Sasa Paporovic (melchiaros)]

The full stacktrace:

May be also this:

https://bugs.launchpad.net/ubuntu/+source/orchestra/+bug/911873

[Sasa Paporovic (melchiaros)]

I have "testdrive" given a run.

As far as I remember it uses kvm.

It works.

This intends that this report is like

https://bugs.launchpad.net/ubuntu/+source/orchestra/+bug/911873

says a virt-manager/libvirt problem with orchestra

[Sasa Paporovic (melchiaros)]

Refiling from qemu-kvm to virt-manager, because of comment #9

[Serge Hallyn (serge-hallyn)]

Thanks for reporting this bug.

Is libvirt actually running? what does 'sudo status libvirt-bin' show?

Can you show the result of:

dpkg -l | grep dnsmas
ps -ef | grep dnsmas
virsh net-list
virsh net-start default

And do 'apport-collect 981728' to cause libvirt debug information to be posted to this bug?

My guess is that another dnsmasq is running and keeping libvirt from starting its dnsmasq, as per bugs 231060 and 928524.

[Sasa Paporovic (melchiaros)]

Q:Is libvirt actually running? what does 'sudo status libvirt-bin' show?

Doing apport-collect 981728 cuases a problem:

libvirt-bin is installed. Semms to be a problem with apport?!

[Sasa Paporovic (melchiaros)]

A reassign this to "libvirt-bin" fails. Launchpad switched back to the source package "libvirt", so I could not do apport-collect 981728.

Ok, the VMs which you were trying to start were assigned to
network 'default', but it looks like 'default' is not defined.

[Sasa Paporovic (melchiaros)]

Q:

A:

user@userhost:~$ virsh net-list --all

-----------------------------------------

user@userhost:~$ sudo virsh net-list --all
[sudo] password for user:

user@userhost:~$

[Sasa Paporovic (melchiaros)]

"Automatischer Start" means "automatic starting"

Well, it is defined with comment #17.

Before installing orchestra(original I guess virtualbox) it works fine with default.

--------------------------

To mark it out: All guests are affected. Not only one.

[Sasa Paporovic (melchiaros)]

But sure there are all on "default" network.

[Serge Hallyn (serge-hallyn)]

Ok, then I still think this is a dup of bug 928524. Can you please

sudo stop libvirt-bin
sudo mv /var/log/libvirt/libvirtd.log /var/log/libvirt/libvirtd.log.1
sudo start libvirt-bin
net-start default

and then attach /var/log/libvirt/libvirtd.log to this bug?

[Sasa Paporovic (melchiaros)]

Little problem with net-start:

user@userhost:~$ sudo stop libvirt-bin
[sudo] password for user:
libvirt-bin stop/waiting
user@userhost:~$ sudo mv /var/log/libvirt/libvirtd.log /var/log/libvirt/libvirtd.log.1
user@userhost:~$ sudo start libvirt-bin

user@userhost:~$ net-start default

user@userhost:~$ sudo net-start-default

[Serge Hallyn (serge-hallyn)]

Sorry, I meant

sudo virsh net-start default

From libvirtd.log:

Please uninstall dnsmasq if possible. Marking this as a duplicate of bug 928524
