Hi all,

Maybe this is a known issue, but I had pxe boot working with libvirt 0.7.1

This config:

<domain type='kvm'>
        <boot dev="network" />
        <console type='pty' />
        <interface type='bridge'>
            <source bridge='br1' />

Creates the following output with libvirt 0.7.7:

[root at localhost data]# virsh create --console pxetest.xml
error: Failed to create domain from pxetest.xml
error: internal error Process exited while reading console log output:
char device redirected to /dev/pts/0
Cannot boot from non-existent NIC

Here's the log:
LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin /usr/bin/qemu-kvm -S -M
fedora-13 -enable-kvm -m 192 -smp 1,sockets=1,cores=1,threads=1 -name

libvirt 0.7.1 nicely presents the pxe menu on the console. Here's the
qemu cmd under libvirt 0.7.1:

LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin /usr/bin/qemu-kvm -S -M
