.... I have a 64-bit CentOS 5.6 VM running on a 64-bit FC14 host,
libvirt 0.8.3-10.fc14, 64-bit. I am getting messages in my syslog file,
2 about every 20 min. about dnsmasq:

They are washing other stuff out of easy view .... Is there a way to
silence these messages ? Also, my ifconfig shows:

Is there a way to get vnet0 to use IPV4 ? Where is that configured ? I
presume that it (vnet0) is the server/host end of the virbr0 bridge,
what type of interface is it ? The online docs are good & voluminous,
but I haven't (yet) found any info on this question. In fact, the pages
I have seen where brctl commands are shown show nothing for the
interface of virbr0 (empty space, no output), where mine shows:
[root at Q6600:/etc, Wed Aug 17, 10:19 AM] 1256 # brctl show
bridge name bridge id STP enabled interfaces
virbr0 8000.fe5400a498a3 yes vnet0
[root at Q6600:/etc, Wed Aug 17, 10:19 AM] 1257 #
hence my questions about vnet0 :-) .... TIA for any clues ....
