Re: [Xen-devel] Xen-Unstable : no eth0 when boot up

["Yan Li" <yan_li00@xxxxxxxxxxx>]

ok, now it works. I found you set e100 enabled in defconfig-xen0. So I just
cloned it again and build it all over again, and it works fine. Thank your
help.
btw, I have a question about how xen handle the system calls. Xen has fast
trap mechanism. But when we commented out the line
    "HYPERVISOR_set_fast_trap(SYSCALL_VECTOR);"
in xenolinux-2.4.26/arch/xeno/kernel/traps.c, (talking about 1.2 here)
xen still performed well. So xen must have something to handle system calls
from guest OS, right? but we cannot find where it did this. It seems to us
xen only defined 0-19, not 128 for system calls.

Thanks,
Yan
