Re: My VMs don't get IP with libvirt and dnsmasq

[Computers Issues <computerslover123@xxxxxxxxx>]

Hello!

Thanks for your answer.

Well, I think it has to ask for an IP as I have the same configuration in a different machine (with the same OS) and it works, there I see the DHCP packets and so on, but not here. And yeah, that pepito.conf file exists, this is its content:

##WARNING:  THIS IS AN AUTO-GENERATED FILE. CHANGES TO IT ARE LIKELY TO BE
##OVERWRITTEN AND LOST.  Changes to this configuration should be made using:
##    virsh net-edit pepito
## or other application using the libvirt API.
##
## dnsmasq conf file created by libvirt
strict-order
user=libvirt-dnsmasq
pid-file=/var/run/libvirt/network/pepito.pid
except-interface=lo
bind-dynamic
interface=virbr2
dhcp-range=192.168.150.2,192.168.150.254
dhcp-no-override
dhcp-authoritative
dhcp-lease-max=253
dhcp-hostsfile=/var/lib/libvirt/dnsmasq/pepito.hostsfile
addn-hosts=/var/lib/libvirt/dnsmasq/pepito.addnhosts

There is nothing obviously wrong with XMLs. Couple of things to try:

1) are you sure that the guest actually ask for an IP address? What
happens when you 'dhclient eth0' from inside the guest (or whatever the
equivalent is)?

2) is dnsmasq running on the host? If so, there should be
/var/lib/libvirt/dnsmasq/pepito.conf file, can you share its content?

3) Firewall. A lot of times when something network related doesn't work
I shut the firewall down and retry. It helps me rule one possible source
out.
