Hello, guys,
This time I build a new Vserver enabled kernel and GPE package, now solved
the "Illegal instruction" on ARM.
But I tried "vcmd -i 42 -C ctx_create -- ps auxwww", it just simply hung(but
I can interrupt the command).
Any approach to solve this?
Btw, I tried below command for the vserver kernel, seems OK.

Seems everything is fine, but why vcmd cannot be run correctly? (I can run
vcmd correctly on my PC machine)
Thanks,

However seems vserver kernel has some problems.
[EMAIL PROTECTED]:/# vserver-info
Versions:
Kernel: 2.6.16.13-vs2.0.3-rc1-ezx6
VS-API: Illegal instruction
[EMAIL PROTECTED]:/# vserver-stat
Illegal instruction
Strange, any possiblities?
Thanks,
