Hello,

There are such VE parameters: CPUS and CPULIMIT (--cpus and --cpulimit), that control how much cpu power to give to VE. This parameters also affect contents of /proc/cpuinfo. For example, if you give
# vzctl set 103 --cpus 1 --save
command on the node with two cpus, only one cpu will be visible from VE 103.
If you give:
# vzctl set 103 --cpulimit 50 --save
command on the node with CPU of 2400Mhz, only 1200 Mhz will be visible from /proc/cpuinfo

Read man-page on vzctl for more information.

There is no possibility to change CPU Vendor/Model/features...
