Hi, I''ve been struggling the past couple of days to install Zen 3 on FC4. The readme guide makes it sound simple, but I''ve had nothing but error after error and seem to have hit a complete dead end. Please could someone give me a guide, or tips if they have done this themselves. I did manage to get a kernel to compile, but it didn''t have the right drivers for my RAID 10 SATA hard disk (4 disks). I looked at a working install of FC4 and it looks like it uses SCSI drivers to get it working. I then had no luck running "make ARCH=xen xconfig", so I tried copying over a .config from the FC4 kernel and that wouldn''t make. I''ve now resulted to installing the xen2 unstable that comes with Fedora, but this isn''t what I''m after. I need something with as few bugs as possible. Please, please, please HELP!

I am not a Fedora/xen expert, but I see that answering you questions is hard for others without additional information.> I did manage to get a kernel to compile, but it didn''t have the > right drivers for my RAID 10 SATA hard disk (4 disks).Then you need to compile an own kernel with the needed drivers.> I looked at a working install of FC4 and it looks like it uses SCSI > drivers to get it working.Yes, SATA disks need SCSI drivers, I can tell from my experience(at lest those I have need SCSI to run nicely with DMA). So this is completely O.K.> I then had no luck running "make ARCH=xen xconfig", so I tried copying > over a .config from the FC4 kernel and that wouldn''t make. >What do you mean with "had no luck"? If the config stuff doesn''t work in first place, something is completely wrong there. Did you try using menuconfig instead of xconfig? (xconfig will obviously not work on a console based system. What config did you copy over, a plain fedora kernel config without xen? That wouldn''t work well to create a xen kernel. What happened exactly when it "wouldn''t make"?

Hi Henning, Thanks very much for your help. I''ve never configured a Kernel before. The make ARCH=xen menuconfig Command worked. I''ve added support for SCSI and RAID10 so hopefully that''ll do it. The error I was getting with make ARCH=xen xconfig was:- /usr/bin/ld: cannot find -lqt I have qt installed with all the required packages -devel, etc. I''ve read posts about -lqt now being -lqt-mt which is what I appear to have:- ldconfig -p | grep qt shows libqt-mt.so installed. I don''t know how to get it to pickup the right libqt-mt.so file. I''ve tried creatig a link and a symbolic link (ln -s libqt-mt.so libqt.so) and updating ldconfig but neither worked.

Hi All, The problem I''ve been having it explained on this site:- http://www.option-c.com/xwiki/Xen_Errors#Kernel_panic:_VFS:_Unable_to_mount_root_fs_on_unknown-block.282.2C0.29 I''ve now rebuilt the kernel including the SCSI support. Looking at my fedora kernel boot it''s using the aacraid SCSI driver. I selected that driver as an option when I built the xen kernel. If I reboot with Xen I still get the same error. So I tried making an initrd:- mkinitrd /boot/initrd-2.6.12.6-xen0.img 2.6.12.6-xen0 I get the error:- No module aacraid found for kernel 2.6.12.6-xen0, aborting. So I copied over the SCSI drivers folder from the /lib/modules fedora kernel, then mkinitrd worked. I updated grub.conf, rebooted. Finally Xen booted! I tried booting again without the initrd image and I got the error again. Should I have copied the aacriad module somewhere before I built the kernel? It seems like it won''t load it witout the image. At least now I''ve got something I can play around with. I''ve included the error message below so that people can find this post with google if they experience the same problems. Root-NFS: No NFS server available, giving up. VFS: Unable to mount root fs via NFS, trying floppy. VFS: Cannot open root device "sda9" or unknown-block(2,0) Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on unknown-block(2,0) Lyle ------------------------------------------------------------ Lyle Hopkins - CosmicPerl.com CGI Scripts - Internet software solutions for the professional webmaster Email: webmaster@cosmicperl.com Web site: http://www.cosmicperl.com Specializing in Affiliate Software solutions ------------------------------------------------------------ ----- Original Message ----- From: "Xen" <xen@cosmicnetworks.com> To: <xen-users@lists.xensource.com> Cc: "Henning Sprang" <henning_sprang@gmx.de> Sent: Tuesday, February 07, 2006 2:08 PM Subject: Re: [Xen-users] Upgrading to Xen 3 on Fedora Core 4> Hi Henning, > Thanks very much for your help.

Anyone could explain me how can i obtain the 1st screenshot configuration? http://www.cl.cam.ac.uk/Research/SRG/netos/xen/screenshots/ where have i to install vnc server and where viewer?... where is running kde and gnome? thanks _________________________________________________________________ Videochiamata?

We set it up to start at boot time, but you can equally just xm console to the domain and start it manually. Run a VNC client in dom0 to connect to it. You''ll get the domU''s desktop appearing in a window. In the screenshot you''re looking at, the outermost KDE is running in dom0 (which controls the screen). The "Remote Desktop Connection" windows are connected to the VNC servers running in the 4 domUs. I used the KDE Remote Desktop Client for that screenshot, because it can do live rescaling of the remote desktop (which I needed to make all the windows fit in one screenshot!!!)

We''re running KDE in domain 0 (which is a Redhat 9.0 install), with VNC connections to 4 other domains visible. The other domains are running SuSE (top left), Fedora Core 1 (top right), Knoppix (bottom left) and Fedora Core 2 (bottom right). The VNC servers will be running in the guests and the viewer in dom0. Hope that helped.
