I can only see 1 vcpu in xenU guest, even if I have set vcpus=4 in config file.
xm vcpu-list shows:
Name                              ID VCPUs   CPU State   Time(s) CPU Affinity
Domain-0                           0     0     1   -b-    4147.9 any cpu
Domain-0                           0     1     3   -b-     512.2 any cpu
Domain-0                           0     2     2   r--     266.6 any cpu
Domain-0                           0     3     0   -b-     294.2 any cpu
sda4                               3     0     0   -b-       3.1 0
sda4                               3     1     -   --p       0.0 1
sda4                               3     2     -   --p       0.0 any cpu
sda4                               3     3     -   --p       0.0 any cpu

Reproduce steps:
----------------
1. set vcpus=4 in /etc/xen/xmexample1
2. xm cr -c xmexampl1
2. cat /proc/cpuinfo in the guest and can see only 1 cpu
3. xm vcpu-list shows all other cpus are paused.
