The bugzilla says "But it'll effect to dom0.", does this mean that xl vcpu-set domU 4 will actually set dom0 to 12 vcpus? Or does it just mean that xl vcpu-set 0 4 works where xl vcpu-set domU 4 does not? There's quite a bit of potentially useful info missing from the bug report, like guest config details, xenstore content etc, http://wiki.xen.org/wiki/Reporting_Bugs_against_Xen has a list of various log files which are often useful to help solve bugs, please do consider including those which seem relevant on future bug reports.

'xl vcpu-set domU 4' doesn't work for dumU at all. 'xl vcpu-set' for dom0 also has a bug. You can use 'xl vcpu-set' command to decrease vCPU number for dom0; but when you try to increase its number you might meet dom0 panic.
