[Xen-users] XEN ignores vcpu setting

[disconnect <disconnect@xxxxxxx>]

CPU: Intel Core2Quad Q6600
MB: Intel DQ35MP
MEM: NCP 4x2GB PC2-6400
HDD: 4xWD2500AAKS

I'm trying to run Fedora9 in paravirt. DomU and allocate 2 VCPU's and 4GB of
mem. This is my /etc/xen/Fedora9 config:
name = "Fedora9"
uuid = "80601cf5-109d-1737-e3f3-74b5f3cfabcd"
maxmem = 4096
memory = 4096
vcpus = 2
bootloader = "/usr/bin/pygrub"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
vfb = [ "type=vnc,vncdisplay=0" ]
disk = [ "phy:/dev/md1,xvda,w" ]
vif = [ "mac=00:16:3e:79:bb:59,bridge=xenbr0" ]


The problem: Fedora9 DomU uses one VCPU ignoring vcpus setting in
/etc/xen/Fedora9.
I tried disabling SELinux in both Dom0 and DomU but it did not help.

The 'xm list' command prints me that DomU have only one VCPU (while i
specified two in /etc/xen/Fedora9):
Name                                      ID Mem(MiB) VCPUs State   Time(s)
Domain-0                                   0     3885     4 r-----     24.2
Fedora9                                    1     4096     1 -b----      8.4

but 'vcpu-list' command prints me this:
Name                              ID VCPUs   CPU State   Time(s) CPU
Affinity
Domain-0                           0     0     0   -b-      12.8 0
Domain-0                           0     1     1   -b-       3.8 1
Domain-0                           0     2     2   -b-       4.9 2
Domain-0                           0     3     3   r--       2.4 3
Fedora9                            1     0     3   -b-       8.2 any cpu
Fedora9                            1     1     -   --p       0.0 any cpu

One of DomU's VCPU's in paused state :E
I tried pause/unpause DomU, but it did not help.
Setting vcpu-pin's didnt help too (i tried rebooting DomU after changes)
xm vcpu-pin Fedora9 0 2
xm vcpu-pin Fedora9 1 3


any ideas?
