Resend the patch again with 3 fixes:

1)  Change   'if (!info->spicehost)' to  'if (info->spicehost)' ,
sorry for my carelessness
2)  In the new spice, the spice option of spiced qemu is "addr=
hostaddr " not "host=hostaddr",
      according to the new qemu's file qemu-options.hx
3)  Delete 'printf("SPICE Options:\n  -spice %s\n", spiceoptions);' ,
which is not necessary.


Testing this patch on xen-unstable, I think there is no problem now.

Thanks

This patch allows you to use spice for
xen-upstream-qemu on upstream Xen or released Xen-4.1.0.

Nothing need to be modified in xen-upstream-qemu,
because qemu has include spice's code as a new feature since qemu-0.14.

= Usage =

Add spice fields in VM cfg file.

e.g.

spice=1
spiceport=6000
spicehost='192.168.1.187'
spicedisable_ticketing = 0 # default is 0
spicepasswd = 'password'
spiceagent_mouse = 1 # default is 1
