Hi, What is the preferred OS to use with XEN, as the dom0 host? We primarely us CentOS (currently 5.6) but it seems that the native XEN that comes with CentOS is a bit behind. What is the preferred OS to run on the dom0''s? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

There will be missing features (e.g. vga console, blktap) and bugs. They''re continually being fixed (see xen-devel list archive), but I wouldn''t recommend either git version or current upstream kernel for production. It might be a different story if all xen-related features are already accepted upstream (either in kernel, or in userspace qemu). But again, if your concern is stability, I''d recommend to just stick with Centos, or go with XenServer (even XCP might be too bleeding-edge for your needs). RHEL5 is still being supported until 2014 (or 2017 if you have extended life cycle support), so Centos should follow as well. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

What is the current native XEN version on Debian or OpenSuse? I couldn''t find anything definate. Some sources suggest 4.0, others 4.1 - how stable is XEN 4.x at this stage?

Is there ANY linux distro which: - comes bundled with Xen 4.x - comes with supported dom0 kernel (i.e. not third-party like ppa) which supports blktap (including tap:vhd) - supports memory resize using "xm mem-set" - supports CPU hotplug using "xm vcpu-set" without having to do additional settings (e.g. without having to do echo 1 > /sys/devices/system/cpu/cpu2/online) - has no cirtical xen-related bug within the last 3 months I haven''t found it, which is why I say stick with RHEL/Centos if you want "stable"> > And what about Slackware / Gentoo or other similar Linux distro''s? > > > > My problem with CentOS is that CentOS 6 (rather RH6) doesn''t have > native XEN anymore so our upgrade path looks a bit uncertain right > now. > > > Isn''t XenServer built on CentOS as well? > What *real* benefit will I have in using XENServer instead of CentOS + XEN? >Mainly support.

Generally when you move fromvirtualization to clouds you''re talking about dynamics. With a cloud you can have loadbalancing where VMs are moving around depending on resource allocation and load etc.. With the open source Xen this was a harder thing to do because the user space tools weren''t that great. In XCP/Xenserver you''re using the same Hypervisor but everything is through XAPI so you create pools of resources like storage, hosts and VMs. The idea is that everything is abstracted and dynamic. The difference between XCP and XenServer is that the former is sort of the beta, community version. I has new stuff like OpenVswitch but missing heavy hitting features like load balancing. It''s also running a newer version of Xen/Linux kernel than XenServer. for the most part XenServer is recommended for production and XCP if you want to be on the bleeding edge. If you want to see the difference in approaches look at the man pages for the xm command and the xe command. To answer the earlier question, I''m moving my Open Source Xen servers to XCP. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Since someone mentioned Gentoo... ... just a heads-up, some of us in the Gentoo community are experimenting with Gentoo as Dom0 (interim codename "Xentoo"). As of this posting, PV DomUs started okay, no idea (yet) about HVM DomUs. That said, remember that with Gentoo you don''t have an ''out of the box'' ready-to-use system. You have to build the kernel yourself, and there might be some complications in managing tens of Xentoo servers. We''re still some way away from solving this... uh, inconvenience.

I thought about rolling back to 1.0 but there''s really not a lot of difference. My biggest complaints so far is 1) we really really need to get XCP repos working. To upgrade all my hosts will require wandering around with a USB DVD drive since none of them have optical disks of their own. 2) all the guis for it (outside of XenCenter) are either overly complex or very buggy. After I get this migration done I may dedicate some time to this issue. OpenXenManager would be decent if it worked reliably. In the coming weeks I''ll start putting XCP howtos up on my site as I get to them. Coming from OSS Xen there''s a bit of a learning curve.

I''ve got it working inside a Virtual Box VM, which makes testing HVMs impossible, but I don''t see any reason why that shouldn''t work. It''s just a matter of enabling the support. One of the goals of the Xentoo-project is to find out the absolute minimum needed to get it to run. For now, libvirt and virtmanager should be usable as a management tool (along with some others that are around) If you''re looking for an out-of-the-box solution, XCP or XenServer sounds like a good starting point to me. -- Joost _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Rudi,> Does anyone use XEN with Scientific Linux? > > What version do you run, and what''s your experiences with it so far?Running four Scientific Linux 6.1 boxes in a heavy testing environment here, with Xen 4.1.1, and kernel from M A Young (http://xenbits.xen.org/people/mayoung/testing/x86_64/), because his kernels are by far closest to RedHat''s specs. Works very well. No problems so far. (Scientific Linux is essentially just another RHEL-clone, which gives you the option to install extra bits, but by default doesn''t do so.) As guest OS, I''m running CentOS 5.6 (PV), Scientific 6.1 (PV), FreeBSD (both HVM and PV).

Hi, I use XEN 4.x in production since years. I never had any problems with it. But on the other side Debian and XEN is not bleeding edge. But it is well tested and works out of the box (at least for me). At the moment I use it on 4 servers and a 5th as test system. I use a self compiled and patched 3.0 Debian kernel (I use the kernel source package from Debian unstable) because I need support for SCST in the kernel.

Of course CentOS 6 works out of the box as a domU.> OR, is XEN busy dying a slow death and I should rather look @ VMWare or KVM?I can''t speak for VMWare. KVM is a toy compared to Xen (I use KVM to run windows programs on my ubuntu desktop). The hypervisor / dom0 approach of Xen just can''t be beat for serious server-level virtualisation, imo. Anyone who tries to tell you that KVM is a suitable substitute needs to get their head checked. As far as the attitude of Xen dying is concerned, tell that to Rackspace or Amazon or Linode or any of the several other VPS providers who run their business on Xen.
