Hi. I have been trying to boot into xen and whenever I try, xen automatically reboots. I tried using the noreboot option to try and track down the source of the error, but the only information I get is that the kernel switched from SMP to UP mode. All of my troubles with xen started when I upgraded my processor from a T2050 to a T2400. The biggest two differences between the T2050 and the T2400 are that the T2400 supports Intel''s VT-x extensions and is modestly faster at 1.83GHz instead of 1.60GHz. The same problem happens both when trying a native installation of xen and when trying to boot from the xen live CD. Can anyone tell me what could be happening and how I could go about fixing this problem? Thanks in advance. -- Luck is believing you are lucky. -- Tennessee Williams _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

It should work for most hardware, and has Xen built in. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

The thing is, the state of kernels > 2.6.18 (including current Debian/Ubuntu kernel) is not as well-tested as 2.6.18. AFAIK only Suse officially supports dom0 kernel with 2.6.31. So my guess is you hit a bug that exists in newer kernel. The reason I suggest RHEL is because they actively maintain their 2.6.18 kernel, backporting drivers and bugfixes. So it''d be much easier for you to start with that. Once you have it working, you can easily use Redhat kernel on Debian if you want, or start compiling your own kernel. -- Fajar> > On Fri, Dec 4, 2009 at 1:14 PM, Fajar A.

Two Linux distros that I know of with Xen dom0 support are RHEL/Centos and Suse/Opensuse.> In that case, what purpose does a GNU/Linux > installation serve for dom0?

It consists of kernel with xen dom0 support (xenified or pv_ops), and the normal libraries and programs that comes with standard installation. It behaves mostly like a normal installation, with the main difference that it doesn''t have access to all CPU and memory. dom0 can be Linux, Opensolaris, or *BSD. xen userland tools (e.g. xm) basically controls the hypervisor and dom0, telling it stuff like "you need to provide this much resource to this domain" A functional Xen installation needs all three components.> > Since I''m so new to xen, could you also give me a recommended partition > setup for a system that will run virtualized instances of both Windows XP > and Debian GNU/Linux? Are there any other resources you would recommend I > look into?For normal uses, any partition setup would do just fine. If you want high disk I/O performance though, you should use LVM setup, leaving some unused space for domU storage. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
