Hi folks!

 After upgrading my Xen-3.2.0 to new Xen-3.3.0/Linux-2.6.18.8-xen-3.3.0 my domU /proc/cpuinfo shows only:

administrativo@vsrvXX:~$ cat /proc/cpuinfo
processor    : 0
vendor_id    : GenuineIntel
cpu family    : 15
model        : 6

cpu MHz        : 3391.500

bogomips    : 6785.83
clflush size    : 64
cache_alignment    : 128

 But before upgrade, it's cache was the same of my dom0, look my dom0 cpuinfo:

root@hyper02:~# cat /proc/cpuinfo
processor    : 0

cpu family    : 15

How to give more cpu cache to my domU in new Xen-3.3.0? My domUs are very slow now!
I do not use HVM, all my Linux domUs are paravirtualized.

Thanks!
Thiago
