[libvirt] [PATCH] Increase size of buffer for xend response

[Jim Fehlig]

On systems with many pcpus, the sexpr returned by xend can be quite
large for dom0 when it is configured to have #vcpus = #pcpus (default).
E.g. on a 80 pcpu system, where dom0 had 80 vcpus, the sexpr details
for dom0 was 73817 bytes!  Increase maximum buffer size to 256k.
