Xen Kerenl + ipw3945
by Justin Conover 27 Oct '06

27 Oct '06

Does anyone know if the ipw3945 wirelss card has worked or can work with a Xen kernel. The ipw3945 bits from freshprms.net work fine with FC6 kernel, but if I boot using the Xen kernel than it does not work. Thanks,

How can I boot using CD-ROM/ ISO?
by Tiago Cruz 26 Oct '06

26 Oct '06

Hello guys, I'm trying create one virtual machine following the document "xen_install_windows.pdf", but I'm not able to boot, please see: [root@xen xen]# xm create -c fedora6 Using config file "fedora6". Error: Not an HVM capable platform, we stop creating! So... what's HVM? I don't have VT on this processor, I need this only to use my CD-ROM (or one ISO file) to do one new installation? Thanks a lot!

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi folks, I installed sucessfully 2 virtual machines on a fedora core 6 system. When I try to use the grub command "pciback.hide", I retrieve an error message while booting my dom0...

Congratulation for this great Release FC6
by Thomas von Steiger 25 Oct '06

25 Oct '06

I like to congratulate to all the involved people they have build this great Release Fedora Core 6 with Xen 3.0.3 ! Reinstall of dom0 with fc6 and restore only the guest hvm config files. After this startup of all the existing guests without any problem, wonderful. I think to have a small downtime for a dom0 it's possible to install a new FC6 as guest and prepare this guest to boot finaly as new dom0. I'm looking forward to the future to implement projects and platforms with this great technology. Greetings from Switzerland. Thomas

Unable to install unmodified guest FC5 in dom0 FC6 Test 2
by Ranganathan, Shobha 25 Oct '06

25 Oct '06

I have a Fedora Core 6 Test 2 host Os and am trying to install unmodified guest FC5. I used xenguest-install.py to generate a config file for me. This I edited to get to run unmodified guest but no success yet. When I do "xm create xenbox_G3FC5" it says "Started xenbox_G3FC5" but I do not see a window which can allow me to do Linux OS install. name = "xenbox_G3FC5" builder = "hvm" memory = "256" uuid = "b18f6bb7-ac4c-b8e7-fb59-0097fea1c73e" disk = [ 'file:/root/xenguest3,ioemu:hda,w' ] boot="d" cdrom="/root/FC-5-i386-DVD.iso" vif = [ 'type=ioemu,bridge=xenbr0,mac=00:16:3e:42:ac:69' ] on_reboot = 'restart' on_crash = 'restart' kernel = '/usr/lib/xen/boot/hvmloader' device_model = '/usr/lib/xen/bin/qemu-dm' sdl = 1 # use SDL for graphics vnc = 1 # use VNC for graphics vncviewer = 0 # spawn vncviewer by default nographic = 0 # don't use graphics serial='pty' # enable serial console Regards Shobha Ranganathan "The significant challenges we face cannot be resolved at the same level of thinking we were at when we created them."

[ANN] Cobbler 0.3.0 / Xen provisioning / call for feedback
by Michael DeHaan 24 Oct '06

24 Oct '06

A while ago I announced cobbler (http://cobbler.et.redhat.com) on kickstart-list, and one of the users there asked why they never heard about it on any of the Xen lists... so, here goes this email... Cobbler is a provisioning tool designed to abstract the differences between PXE, Xen, and "running Linux box" provisioning. It does this by using a helper tool called "koan" to do the Xen and "existing OS" bits. It's intended to be used either as an application or as a library/application (note: GPL) underneath a larger app. What's potentially interesting here is you can have a fedora tree, mirror it, and get Xen provisioning set up off of it rather quickly. Example: on "boot server" # cobbler --import --mirror=rsync://mirror.example.com/fedora-linux-core --mirror-name=fedora-linux-core # (potentially edit xen parameters in /var/lib/cobbler/profiles or define new profiles) # cobbler sync on "target machine" # koan --xen --profile=<name-of-profile> --server=bootserver.example.com What profiles do is they associate the distribution (the initrd and the kickstart plus metadata) with xen parameters (things like filesize required, RAM required, etc) and make it very easy to reproduce and automatically install the same virtual machine install multiple times. At a minimum level, this means kickstarting Xen and not needing to remember the correct parameters to use for xenguest-install each time. There is the added bonus of the PXE+re-provisioning features for bare metal, but they really don't apply to the fedora-xen list. (Disclaimer: Koan should be using the xeninst-devel package for installing Xen. But it's not. This is currently because it tries to play nice with distributions that don't have that package. This needs to change soon. Until then, the install code is heavily based on older versions of xenguest-install, but it works, and I just did an install of FC-6 GOLD recently.) One feature that definitely needs to be added (and is in the works) is to do the install of the remote Xen image from the boot server, without having to log on to the remote bare metal machine that is running the dom0. Cobbler can already do this for bare metal using: "cobbler enchant --profile=<profile_name> --address=<address_of_machine_to_reinstall>" Anyhow, check out the website and the app if interested, and if you have any feedback/thoughts, I'd love to hear it. There's a mailing list set up (https://www.redhat.com/mailman/listinfo/et-mgmt-tools) and cobbler and koan are already in FC-5 and FC-6. The newer versions are waiting on the push, so if you're really wanting to get at them, I'd recommend building from source from the mercurial repository. Michael DeHaan

RE: [Fedora-xen] how to install an FC5 guest Os in FC6 Test2 PAE kernel(host OS)
by Zhao, Yunfeng 24 Oct '06

Yes, you can run FC5 as VMX guest. If you are using the latest xen code, you should have no any problem to run pae guest on pae host.
