xen discuss - Feb 2006 - [xen-discuss] Paravirtualization in Solaris - SPARC and x86

Hello, 

 X86 is notoriously known for being difficult in the virtualizations aspect.

There are some commands which , as Xen papers , describe it , "fail
silently" ,
which means that they don''t create General Protection Violation.

Are  SPARC processors more difficult than x86 or less difficult , in this aspect
of "sensitive instructions",  which trap silently? 

Are there any intentions from SUN to develop processors with virtualization 
support (like Intel  VT-x/VT-i and AMD SVM/pacifica)?

Are there any intentions to release the Solaris Xen source in the near future?

Regards,
IB

Yes, see the white papers describing the SPARC
architecture changes and hypervisor at:
