Failed to compile kvm-88

Failed to compile kvm-88

[Jun Koi]

Hi,

I am trying to compile kvm-88, like followings:

./configure --disable-xen
make

Then I get following errors. Why do I have such a problem, if I
already disalbe Xen support, like above? How to fix this problem?

Thanks lot,
J

Comment out all XEN related thing in qemu-kvm/Makefile(search "XEN" then 
comment them), then remake.

Anyone can figure out a more peaceful fix for this? I think compile failure 
w/o --disable-xen is still a issue.

hmm, that was actually my fault. i should clean up the mess, before recompiling.

i fixed that with "make clean", then  "./configure --disable-xen",
then "make". it went well.

thanks,

Oops, I once think --disable-xen didn't work, then just comment all the thing 
out...

Well, I still a little unhappy about --disable-xen must be explicit set. It 
should be configure script's work to figure if fit the compilation 
requirement...

agreed. that would be much nicer if "./configure" can tell us that
"make" would not work, because Xen support is not available. we should
not wait until "make" to spit out the error message.

It's fixed in upstream QEMU.  With Avi on holiday, it may take a little 
unless Marcelo cherry picks or does a qemu merge.  It's
