Hi all,

The xen documentation at http://wiki.xensource.com/xenwiki/CreditScheduler states that the max weight you can set for a domU is 65535. To verify this I decided to try setting 65535 to my dom0 which had no domUs running at the time. I was unable to set a weight of 65535. The server is a duel quad core (8 cores) with 32GB RAM running Centos 5.4/xen-3.0.3-94.el5_4.3 . The maximum weight I was able to set on this server is 32767.  Any idea why am not able to take advantage of the maximum weight.

[[root@node1 ~]# xm sched-credit -d 0 -w 65535
Error: (11, 'Resource temporarily unavailable')
Usage: xm sched-credit -d <Domain> [-w[=WEIGHT]|-c[=CAP]]
