[Xen-users] which processor family to select for Dom0 kernel based on Linux 2.6.18
I am having a Debian uname -a shows Linux debian 2.6.26-2-686 #1 SMP Wed Aug 19 06:06:52 UTC 2009 i686 GNU/Linux I downloaded from http://www.xen.org/products/xen_source.html Linux 2.6.18 with Xen 3.4.x support source tarball, updated for Xen 3.4.2 I am not clear on following 1) Do I need to download and install Xen 3.4.2 (hypervisor and tools) official source distribution which is another download given on this page if I compile the above xenified kernel or will it get xen also installed via some script in my system. 2) When I untarred the files I did a make menuconfig and Processor type and features -----> Processor Family it showed me options from 386 upto VIA c3-2 it is showing me Pentium MMX,Pentium Pro,Celeron ,Pentium 4 but it is not showing me Core 2 Duo which I have how can I get it done enabled in kernel ? -- http://www.abhitech.com _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] which processor family to select for Dom0 kernel based on Linux 2.6.18
So where can the Xen kernel or the hypervisor be worked upon which are downloaded from http://www.xen.org/products/xen_source.html or is there any other way I can compile a Xenified Kernel from source and use it on my machine.

You don''t need to choose Core2 Duo. You choose the best available/possible based on your environment. Like said, the 2.6.26-2-686 kernel you are running is NOT optimized for Core2 Duo, it''s _generic_ kernel.

I downloaded the second download mentioned there Linux 2.6.18 with Xen 3.4.x support source tarball, updated for Xen 3.4.2 do I need to download the hypervisor given there seperately or this one has hypervisor also which I can compile along with this kernel then I copied the conf file from /boot from a machine which is also having Core2Duo and CentOS installed on it on which xm list shows me Dom0 running and the this conf file I am using on the Debian machine to be able to compile the kernel so that I get less errors while doing so I came to know that RHEL,SLES,CentOS all other major vendors which ship xen on the DVDs which normal users use the conf file for each of them are different I searched through your wiki Read http://wiki.xensource.com/xenwiki/Dom0 http://wiki.debian.org/Xen#Dom0.28host.29 and on this link http://wiki.xensource.com/xenwiki/XenParavirtOps there is mentioned about * CONFIG_XEN=y * CONFIG_XEN_MAX_DOMAIN_MEMORY=32 * CONFIG_XEN_SAVE_RESTORE=y * CONFIG_XEN_DOM0=y * CONFIG_XEN_PRIVILEGED_GUEST=y * CONFIG_XEN_PCI=y * CONFIG_PCI_XEN=y * CONFIG_XEN_BLKDEV_FRONTEND=m * CONFIG_NETXEN_NIC=m * CONFIG_XEN_NETDEV_FRONTEND=m * CONFIG_XEN_KBDDEV_FRONTEND=m * CONFIG_HVC_XEN=y * CONFIG_XEN_FBDEV_FRONTEND=m * CONFIG_XEN_BALLOON=y * CONFIG_XEN_SCRUB_PAGES=y * CONFIG_XEN_DEV_EVTCHN=y * CONFIG_XEN_BACKEND=y * CONFIG_XEN_BLKDEV_BACKEND=y * CONFIG_XEN_NETDEV_BACKEND=y * CONFIG_XENFS=y * CONFIG_XEN_COMPAT_XENFS=y * CONFIG_XEN_XENBUS_FRONTEND=m I opened the conf file copied from CentOS but I did not found some of the parameters which you have mentioned on wiki should be present now that is where my problem is how to get them as it is mentioned on your wiki or where can I locate them> > -- Pasi > >> On Sat, Nov 28, 2009 at 9:20 AM, Gémes Géza <geza@kzsdabas.hu> wrote: >> > Tapas Mishra írta: >> >> So does that mean I will not be able to use it for my Core2Duo I >> >> >> > NO! >> > It means it won''t contain those improvements which were applied to have >> > the kernel work more efficiently on Core2Duo CPUs. >> > As you wrote before currently you are running 2.6.26-2-686 which is a >> > generic unoptimized (optimized for the generic 686 arch) kernel, >> > generally all distribution kernels fall into this category (they aren''t >> > optimized for your particular hardware). >> >> downloaded the latest xenified kernel from >> >> http://www.xen.org/products/xen_source.html >> >> and if its not here then where do I look in for ? >> >> >> >> >> >> >> >> >> >> On Sat, Nov 28, 2009 at 9:08 AM, Gémes Géza <geza@kzsdabas.hu> wrote: >> >> >> >>> Because 2.6.18 didn''t have Core2Duo or post Core2Duo optimizations. >> >>> >> >>>> Thats the problem it is showing me all the variations but not Core 2 >> >>>> Duo so I asked >> >>>> >> >>>> On Sat, Nov 28, 2009 at 12:19 AM, Gémes Géza <geza@kzsdabas.hu> wrote: >> >>>> >> >>>> >> >>>>> Tapas Mishra írta: >> >>>>> >> >>>>> >> >>>>>> I am having a Debian uname -a shows >> >>>>>> Linux debian 2.6.26-2-686 #1 SMP Wed Aug 19 06:06:52 UTC 2009 i686 GNU/Linux >> >>>>>> >> >>>>>> >> >>>>>> I downloaded from http://www.xen.org/products/xen_source.html >> >>>>>> Linux 2.6.18 with Xen 3.4.x support source tarball, updated for Xen 3.4.2 >> >>>>>> I am not clear on following >> >>>>>> 1) Do I need to download and install Xen 3.4.2 (hypervisor and >> >>>>>> tools) official source distribution which is another download given on >> >>>>>> this page if I compile the above xenified kernel or will it get xen >> >>>>>> also installed via some script in my system. >> >>>>>> >> >>>>>> 2) When I untarred the files I did a make menuconfig >> >>>>>> and >> >>>>>> Processor type and features -----> Processor Family it showed me options >> >>>>>> from 386 upto VIA c3-2 it is showing me Pentium MMX,Pentium >> >>>>>> Pro,Celeron ,Pentium 4 but it is not showing me Core 2 Duo which I >> >>>>>> have how can I get it done enabled in kernel ? >> >>>>>> >> >>>>>> >> >>>>>> >> >>>>> For a Dom0 choose whatever fits your processor better. >> >>>>> For a DomU choose the most common denominator of the Dom0''s you intend >> >>>>> to migrate the given DomU between. >> >>>>> >> >>>>> Geza >> >>>>> >> >>>>> >> >>>>> >> >>>> >> >>>> >> >>>> >> >>> >> >> >> >> >> >> >> >> >> > >> > >> >> >> >> -- >> >> http://www.abhitech.com >> >> _______________________________________________ >> Xen-users mailing list >> Xen-users@lists.xensource.com >> http://lists.xensource.com/xen-users >-- http://www.abhitech.com _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
