I have WinXP DomU running all right under Xen 3.0.2 on Intel Pentium D Dual Core Processor (Dell 830 server). But whenever I try to install Linux into DomU (I tried CentOS 4.3 and Fedora Core 4) installation process always hangs. Plus text installation mode for FC4 always crashes VNC. Any ideas on these issues? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] Unmodified Linux. Installation hangs.
Would you mind explaining how you got the Windows XP domU working? I''m on the Dell 830 and was under the impression that it did not provide VT meaning you could not install an unmodified guest OS. I suppose this is because I purchased my 830 before the Pentium D options was available and I''m running Pentium 4. I''m also having trouble installing CentOS 4.3 as a domU, but on a Dell 1850 server running FC5 /xen as the dom0. Thanks. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] Unmodified Linux. Installation hangs.
Yes, My Dell 830 has Pentium D with VT enabled in the BIOS. Installing windows was easy: 1. Create an empty image file with dd. 2. Use /etc/xen/xmexample.hvm as an example config file. 3. Install Windows into DomU form CDROM. As for my troubles with Linux. Paravirtualized Linux works all right. I have a bunch of different flavors of Linux running in that mode: Mandrake, CentOS, Fedora, etc... But I have constant problems with unmodified Linux, i.e. Linux with the native distro kernel, not Xen kernel. Now somehow I managed to install Centos (I had to shut down my WinXP domains for that), but it hangs on boot up process just after uncompressing kernel. xm dmesg shows: (XEN) (GUEST: 29) *** int 15h function AX=E980, BX=E6F5 not yet supported! (XEN) (GUEST: 29) int13_harddisk: function 02, unmapped device for ELDL=81 (XEN) (GUEST: 29) int13_harddisk: function 41, unmapped device for ELDL=81 It''s really funny to be able to run Windows under Linux/XEN but not able to run Linux under Linux/XEN.

Re: [Xen-users] Unmodified Linux. Installation hangs.
Finally I was able to start unmodified CentoOS under XEN 3.0.2. The trick is to not use SMP kernel in DomU.

Re: [Xen-users] Unmodified Linux. Installation hangs.
I haven''t gotten CentOS 4.3 going as a domU on top of FC5 but I did run into the same problem with Xen trying to boot the kernel-smp after install running FC5 domU on FC5 dom0. Which method of installing CentOS worked for you. I just saw an update by the author of rpmstrap but It was for Debian domO.

Re: [Xen-users] Unmodified Linux. Installation hangs.
I have 2 kinds of CentOS 4.3 running under XEN under Different Dom0s (CentOS 4.3 and Mandriva 2006): 1. Paravirtualization. I used an image from http://jailtime.org/ and then shaped it with yum to my needs. 2. Real Virtualization. Installed CentOS 4.3 as unmodified Guest OS (though I hang several times during installation) and booted non-SMP kernel then Serge.

I have Xen installed and working on my Dom0 running FC5, and several domUs also running FC5. I''d like to add paravirtualized CentOS 4.3 domUs. I fooled around with jailtime.org but didn''t get very far.

Re: [Xen-users] Unmodified Linux. Installation hangs.
It''s really easy. 1. Go to http://jailtime.org and download an image you want to use. For example centos:centos.4-3.20060325.img.tgz 2. Download it, gunzip and untar it then. 3. It has 3 files: centos.4-3.img, centos.4-3.xen, centos.swap (root, config, swap) 4. Edit centos.4-3.xen. Replace pathes in the disk = line with the real pathes to your files, add vif = [ '''' ] 5. xm create -c centos.4-3.xen 6.

Create the corresponding .cfg file and boot it with ''xm create -c file.cfg''. Where did you get stuck?

Re: [Xen-users] Unmodified Linux. Installation hangs.
Thanks for the help so far. One simple question, where do I get the vmlinuz-2.6-xenU kernel? [root@db4 ~]# xm create -c centos.4-3.xen.cfg Using config file "centos.4-3.xen.cfg".

Re: [Xen-users] Unmodified Linux. Installation hangs.
You can compile it, see the README file in the XEN 3.0.2 sources. Or you can change that line to use your Dom0 kernel. By default in XEN 3.0.2 Dom0 and DomU kernels are the same.
