Thanks very much. You are very gentle and helpful.
I've fixed the PolicyKit problem in this way :
In :
/usr/share/polkit-1/actions/org.libvirt.unix.policy
I have changed this :
<action id="org.libvirt.unix.manage">
<description>Manage local virtualized systems</description>
<message>System policy prevents management of local virtualized
systems</message>
<defaults>
<!-- Any program can use libvirt in read/write mode if they
provide the root password -->
<allow_any>auth_admin_keep</allow_any>
<allow_inactive>auth_admin_keep</allow_inactive>
<allow_active>auth_admin_keep</allow_active>
</defaults>
</action>
to this :
<action id="org.libvirt.unix.manage">
<description>Manage local virtualized systems</description>
<message>System policy prevents management of local virtualized
systems</message>
<defaults>
<!-- Any program can use libvirt in read/write mode if they
provide the root password -->
<allow_any>yes</allow_any>
<allow_inactive>yes</allow_inactive>
<allow_active>yes</allow_active>
</defaults>
</action>
and boom : QEMU and KVM are connected now. Now,another problem has
emerged. When
I click on "File / New Virtual Machine",nothing happens. At this point,I
did :
sudo virsh net-info default
then :
sudo virsh net-start default
and a lot of shit came out from the manhole [image: :D]:
Error starting network 'default': internal error:
Failed to apply firewall rules /usr/sbin/iptables -w --table mangle
--list-rules: iptables v1.8.9 (legacy):
can't initialize iptables table `mangle': Table does not exist (do you
need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

and :
*marietto at chromarietto*:*~*$ sudo virsh net-info default

-w --table mangle --list-rules: iptables v1.8.9 (legacy): can't
initialize iptables table `mangle': Table does not exist (do you need to
insmod?). Perhaps iptables or your kernel needs to be upgraded.
I tried to fix it with this :
$ modprobe iptable_mangle
modprobe: FATAL: Module iptable_mangle not found in directory
/lib/modules/5.4.244-stb-cbe
so,some options should be enabled inside the kernel,for sure.
I have configured the option "MANGLE" to yes when I have recompiled
the kernel the last time :
CONFIG_IP_NF_MANGLE=y
CONFIG_IP_NF_ARP_MANGLE=y
CONFIG_IP6_NF_MANGLE=y
"unfortunately" I'd configured it correctly,so the error should depend on
something else.
It would have been too easy to fix the error so fast. Suggestions ?
