That is correct.  The effort to maintain a network driver portable to 
more than 10 kernel versions is too great.

Re: The errors appear when compiling kvm-guest-drivers on kernel-2.6.29

2009-04-01 Thread Zhiyong Wu 
In virtio_net.c,

#ifdef COMPAT_csum_offset
if (skb-ip_summed == CHECKSUM_HW) {
#else
if (skb-ip_summed == CHECKSUM_PARTIAL) {

It seems that CHECKSUM_HW is not declared.

In skbuff.h, only the macros below are defined.

/* Don't change this without changing skb_csum_unnecessary! */
#define CHECKSUM_NONE 0
#define CHECKSUM_UNNECESSARY 1
#define CHECKSUM_COMPLETE 2
#define CHECKSUM_PARTIAL 3

Cheers,

I don't think the kvm-guest-drivers are still well maintained (they haven't 
been touched in 5 months). If you are using kernel 2.6.29, it already has 
virtio drivers and you don't need the kvm-guest-drivers tree at all.
