[Xen-devel] How to check PERROR

[xen user <xenworker@xxxxxxxxx>]

For many code in libxc, they use PERROR to print out error messages to
stderr. Could someone tell me where to check these messages? They did
not show up on the screen. I did not find them in xend.log and
xend-debug.log under /var/log/ directory.

Thanks

Shu Xian
