[Xen-devel] When is Dom0 coming into current kernel?
Hello, I want to use Xen as virtual machine under Debian Linux. My question to you is, in what space of time can be expected with a transferring of Xen Dom0 into the current kernel? And why do not you develop Xen simultaneous in the actual versions of Kernel? I think the support of kernel 2.6.18 is very obsolete? Can you give us a date on which we can be expected improvement? Thank you, Andreas _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

It should be done in the next month or so, well in time for Xen 3.4. -- Keir On 8/10/08 08:17, "Andreas Günther" <postfix@it-linuxmaker.de> wrote:> Hello, > > I want to use Xen as virtual machine under Debian Linux.

Re: [Xen-devel] When is Dom0 coming into current kernel?
Thank you Keir, that makes me hope to continue to use Xen. Because there are good features in the software. And the principle of Dom0 and DomU is also unique.

Current (dom0) pv_ops patch queue should be here: http://xenbits.xen.org/paravirt_ops/patches.hg/ Also: http://packages.debian.org/lenny/linux-image-2.6.26-1-xen-686 Debian now has 2.6.26 kernel with xen dom0 support included. It''s based on xensource xenlinux 2.6.18 forward-ported patches by Novell/Suse. -- Pasi> Bye > > Andreas > > It should be done in the next month or so, well in time for Xen 3.4. > > > > -- Keir > >_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

But it''s good to hear that the dom0 support in the near future will be introduced in the main kernel. So thank you for your information Pasi, bye Andreas _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

DomU''s can be both 32bit (PAE) and 64bit, not depending on dom0 used. You need to have new enough Xen hypervisor to support "32-on-64". -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Okay, let me first digest. I must first understand. I''m still learning about Xen. Bye Andreas> Actually you should be able to run 32bit (PAE) dom0 with 64bit xen > hypervisor!

Xen hypervisor on RHEL5.2/CentOS5.2 is 3.1.2+patches. So I think Xen 3.2.x and Xen 3.3.x should both be able to run 32-on-64. Citrix Xenserver 5 (commercial product) uses 32bit dom0 on 64bit Xen hypervisor: http://forums.citrix.com/thread.jspa?threadID=236592&tstart=0 -- Pasi> Bye > > Andreas > > Actually you should be able to run 32bit (PAE) dom0 with 64bit xen > > hypervisor!
