KVM net bug

KVM net bug

[José Antonio]

Hi, First I'm sorry for my english.

I'm using kvm on

    host: Debian GNU/Linux sid
    host kernel: Linux enol 2.6.23-1-amd64 #1 SMP Fri Dec 21 12:00:17 
UTC 2007 x86_64 GNU/Linux
    kvm version 58+dfsg-2 (almost on Debian)
    guest: Debian etch and Windows XP, although I think that problem is 
on any guest
    command: kvm -hda disk.img -net nic,macaddr=<valid mac> -net tap

I describe the problem on Debian: When I execute de kvm command the 
guest work but don't work the net because device eth0 don't exists 
instead of exists eth1 firstly eth2 when I shut down and later I boot 
the guest. Because of this my local net don't work.

Regards,

I'm having a hard time understanding your problem.  Do you have an 
appropriate qemu-ifup script?

Hello,
when you have started the debian guest, take a look if this file exists:
/etc/udev/rules.d/z25_persistent-net.rules
if so, delete it, and reboot your guest. let the mac address always the 
same for that guest. Now you should have an eth0 interface.

I'm starting my debian guests like this:
kvm -hda apache.img -hdb apache_storage.img -m 1024 -boot c -smp 2 -net 
nic,vlan=0,macaddr=00:16:3e:00:00:01,model=rtl8139 -net tap -nographic 
-daemonize

For Windows I use:
kvm -no-acpi -m 1024 -boot c windows.img -net 
nic,vlan=0,macaddr=00:16:3e:00:00:41,model=rtl8139 -net tap -nographic 
-daemonize

Hope this helps,
Regards
Mike
