Hi,all:
I got warning messages as this : WARNING:
"xen_multi_update_va_mapping"
[drivers/xen/blktap2/blktap.ko] undefined! when I tried to build the
blktap2 module. I can see that in linux-2.6.27 lots of changes in file
arch/i386/mm/hypervisor.c, but "xen_multi_update_va_mapping " is not
used in
the blktap2 module. I don''t know why this warning appeared. Can any
body
help me?
And if I insert the module blktap.ko that I build out, the system told
me "insmod: error inserting ''blktap.ko'': -1 Unknown
symbol in module
" . It made me creazy . Kind if you can give me any suggestion.
Thanks,
Lyman

答复: ??????: [Xen-devel] problem of build and install blktap2 module
Thanks for the reply! My blktap2source codes came from XCP dom0 kernel. I still got the message:WARNING: "xen_multi_update_va_mapping" [drivers/xen/blktap2/blktap.ko] undefined! -----邮件原件----- 发件人: Pasi Kärkkäinen [mailto:pasik@iki.fi] 发送时间: 2010年1月7日 20:51 收件人: fanliang 抄送: cqj@huawei.com; xen-devel@lists.xensource.com 主题: Re: ??????: [Xen-devel] problem of build and install blktap2 module On Thu, Jan 07, 2010 at 08:48:20PM +0800, fanliang wrote:> > Thanks, Pasi. > I used kernel-2.6.27 of SUSE11.
