DHCP logging settings
I find that libvirt clogs up syslog with trivial DHCP notifications. I
know how to configure alternate logging with dnsmasq directly via
'log-facility' and/or 'quiet-dhcp' options but the XML format used by
libvirt appears to have no equivalent options. Is there a way to reduce
syslog spam from libvirt without switching to a system-wide dnsmasq service?

Again kea DHCP-Server
Well? I?m not convinced KEA can?t be simple DHCP, though I understand that one
would never know that from reading the KEA documentation.
The following is a complete KEA configuration suitable to do a single subnet. In fact, you could probably get away with slightly less.
I?ve replaced the unique addresses from my environment with placeholders (e.g. <network/mask>), but otherwise, this is a

Windows XP - Explorer crashes when I try to open a file on a Samba share
I am having problems with my samba clients. I am using Windows XP SP1 to
try to connect to a Samba server I have running on my Gentoo Linux server.
Browsing a share works decently well, but I ocassionally have network
problems (the same timeout issue I explain below).
The real problem comes, though, when I try to access a file (either trying
to open it or just right-clicking on it). As soon as I

libvirt/dnsmasq is not adhering to static DHCP assignments
This is basically a continuation of an older posting[0] I found, but
apparently no solution has been posted. So, I'm trying to setup static
DHCP leases with dnsmasq that is being started by libvirtd:

[5.10] PXE + dhcp opts 209, 210 and path issues in tftp/http
Hello,
First, this setup works fine without any error in syslinux 4.06 as show
below.
For convenience, both versions of syslinux 4.06 [#1] and 5.10 [#2]
directories (~2MB each) are uploaded ready for test.
As said before, this is tested on qemu-1.5.0 + dnsmasq 2.66 in Arch
Linux @ 64-bit.
If more info is needed, please let me know.
Good luck!

Re: libvirt/dnsmasq is not adhering to static DHCP assignments
Hi,
It looks like that's the issue:
# cat /var/lib/libvirt/dnsmasq/osc_mgmt.hostsfile
52:54:00:2c:85:92,192.168.80.1,openstack-controller-00
But it makes me wonder...libvirt should be generating and managing this
file right? Do I need to edit this myself or should libvirt be updating
this file? If so then why isn't it?
