[Xen-users] Which processorw are VT or Pacifica enabled ?
Hello Which model of processor are VT or Pacifica enabled ? I''ve got recent XEON but it seems that not support VT. Do it exists a mean under linux to see if a processor is VT enabled ? Maybe a simple cat /proc/cpuinfo ? Regards Sebastien _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Exception would be the budget models of Sempron that don''t have the SVM feature... The reason it''s so simple to tell is that the AMD processors that have SVM also have DDR2, which again means that it needs a different socket - so it''s pretty easy to tell if it''s a new or old processor - the old ones will not fit in the new socket, and vice versa. [I''m not a socket specialist - whether we CHOOSE to change the socket or HAD to is not something I can comment on, but changing socket when changing the type of DRAM supported is probably not really a bad idea... It saves a few people from trying to use the processor with the wrong type of memory and calling our tech-support to wonder why it doesn''t work... ;-)]> I''ve got recent XEON but it seems that not support VT.Aside from the processor, Intel processors also need a BIOS that enables the feature (or doesn''t disable it, at the very least) - I don''t know the details of this [check my mail address, and you''ll probably realize why].> > Do it exists a mean under linux to see if a processor is VT enabled ? > Maybe a simple cat /proc/cpuinfo ?Yes, it should be under "flags" ("svm" in the AMD case, it''s called "vme" in the Intel case). You do need a recent kernel for this to work, but I know 2.6.16.13 is good enough [probably several older ones too]. -- Mats> > Regards > > Sebastien > > > > > > > > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
