Hello
I want to set fixed IP for host (from MAC address) in dhcp. How can I do
it through libvirt configuration?
There is not possibility set it in virt-manager. I can edit manually
ldapnet.xml (ldapnet is name of my network) but:
1. question:
Where is right place to edit it:
/etc/libvirt/qemu/networks/ldapnet.xml
or
/var/lib/libvirt/network/ldapnet.xml
(after reboot one file replaces other but which direction but I didn't
find which direction)
The 'right' place is to use 'virsh net-edit <network name>'. Editing
the
files in place provides no error checking and can require a libvirtd
restart. The user shouldn't have to know where the files are kept.
2. question:
How can I propagate this changes?
Neither
/etc/init.d/libvirtd reload
/etc/init.d/libvirtd restart
changes dnsmasq settings. It is done only during reboot, why?
Before you make the changes, do 'virsh net-destroy <net name>'. This
will shutdown the network (dnsmasq), but NOT delete it in any way. Then
use 'virsh net-edit <net name>' as mentioned above to make your changes.
Finally, use 'virsh net-start <net name>' which will start a new dnsmasq
process.

3. I've found this workaround:
* kill dnsmasq process for this settings
* start dnsmasq with new settings, ex.
.... --dhcp-host 52:54:00:22:a7:76,ldap-m1.ldapnet.tmapy.cz,192.168.241.101
Is it way how to do it through libvirt utility?
