[Xen-users] Xen in RHEL 5.0...Installation problems

Hello..I am not very proficient in Linux kernel stuffs although I know my
basics. I have a question and all suggestions/solutions will be highly
appreciated...
 
 I got to know that RHEL 5 has inbuilt Xen Support...So I tried to install a
RHEL 5.0 Server on my P4 machine. On top of it I tried to install Xen specific
RPMs and some other RPMs needed by Xen.
 
 The additinal RPMs added after base RHEL 5.0 installation are :
 
 
 bridge-utils-1.1.2.i386.rpm
 iproute-2.6.18-4.el5.i386.rpm
 kernel-xen-2.6.18-8.el5.i686.rpm
 kernel-xen-devel-2.6.18-8.el5.i686.prm
 udev-095-14.5.el5.i386.rpm
  
 
 After all this the grub.conf gets modified automatically and looks like this:
 
 # grub.conf generated by anaconda
 #
 # Note that you do not have to rerun grub after making changes to this file
 # NOTICE:  You have a /boot partition.  This means that
 #          all kernel and initrd paths are relative to /boot/, eg.
 #          root (hd0,0)
 #          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
 #          initrd /initrd-version.img
 #boot=/dev/hda
 default=0
 timeout=5
 splashimage=(hd0,0)/grub/splash.xpm.gz
 #hiddenmenu
 title Red Hat Enterprise Linux Server (2.6.18-8.el5xen)
  root (hd0,0)
  kernel /xen.gz-2.6.18-8.el5
  module /vmlinuz-2.6.18-8.el5xen ro root=/dev/VolGroup00/LogVol00 rhgb quiet
  module /initrd-2.6.18-8.el5xen.img
 
 title Red Hat Enterprise Linux Server (2.6.18-8.el5)
  root (hd0,0)
  kernel /vmlinuz-2.6.18-8.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
  initrd /initrd-2.6.18-8.el5.img
 
 
 
 After all this I am ready to boot properly into Xen Specific Linux and the
original RHEL . But there is no /etc/xen directory and nor are the tools like
xend and xm available.
 
 So  I am not sure if I am missing some other RPMS that need to be installed??


On not being able to get it done this way I tried to erase the xen specific RPMs
 kernel-xen-2.6.18-8.el5.i686.rpm
  kernel-xen-devel-2.6.18-8.el5.i686.prm

and installed the RPMs obtained from Xen Source site (for RHEL 5). The RPMs
installed are :
kernel-xen-2.6.18-3.1.0.i386.rpm
xen-devel-3.1.0-1.i386.rpm
xen-3.1.0-1.src.rpm
xen-3.1.0-1.i386.rpm

 

By doing this I see that /etc/xen directory has been created and I can see the
tools xend,xm...

But after modifying the grub.conf and trying to boot into Xen I get kernel
panic.

The grub.conf after modification is :

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
#hiddenmenu
title Red Hat Enterprise Linux Server - XEN ENABLED
    root (hd0,0)
    kernel /xen-3.1.0.gz noreboot
    module /vmlinuz-2.6.18-xen_3.1.0 ro root=/dev/VolGroup00/LogVol00 
    module /initrd-2.6.18-xen_3.1.0.img

title Red Hat Enterprise Linux Server (2.6.18-8.el5)
    root (hd0,0)
    kernel /vmlinuz-2.6.18-8.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
    initrd /initrd-2.6.18-8.el5.img




Some of the kernel panic messages are like:
Reading all physical volumes.
No volume groups found
Volume Group "Vol Group00" not found.
Mount: could not find file system /dev/root
setuproot: moving /dev failed. No such file or directory
.
. 
end-request:I/O error, dev fd0, sector 0





I am including here some details of my configurations:

Did you reboot to the xen-kernel?

That is because you only installed the Xen kernel - you need the
''xen''
RPM from RHEL-5 to get the userspace tools

 I have also tried running mkinitrd to create another init image etc..
 
 I am not sure what is going wrong.

Re: [Xen-users] Xen in RHEL 5.0...Installation problems

Hi Daniel,

I tried to install the following RPMs:

xen-debuginfo-3.0.3-25.0.3.el5.i386.rpm
xen-devel-3.0.3-25.0.3.el5.i386.rpm
xen-libs-3.0.3-25.0.3.el5.i386.rpm

They got installed successfully. But while trying to install
xen-3.0.3-25.0.3.el5.i386.rpm

I get the dependency problem : error: Failed dependencies:
python-virtinst is needed by  xen-3.0.3-25.0.3.el5.i386


I am not sure which rpm to install for this . Also I am not finding the proper
RPM for virt-manager,virt-install.

Are they present in the server image or client image?

Regards
Dushmanta

The python-virtinst  RPM should be on one of the CDs along with the
virt-manager RPMs. Probably in a directory called Virtualization.

IIRC the ought to be present in both client & server images.

If you want to install the virtualization bits you''d use the command
    # yum groupinstall Virtualization
This of course will only work if you setup a yum repository either 
pointing to your installation
    source/tree or another RHEL5 repository.
If have your distribution media mounted as /rhel5tree you can use the 
.repo file below.
Just save it to something like /etc/yum.repos.d/rhel5-ga.repo  If you 
mount your distro tree
    somewhere else just replace rhel5tree/etc... with your local mount 
point (same is true if you
    are using the client bits) , or replace the file:/// directive with 
a network location such as
    http/nfs/ftp if you have your install tree available on the net

#
# rhel5-ga.repo
# should be saved to /etc/yum.repos.d/
#

Re: [Xen-users] Xen in RHEL 5.0...Installation problems

well ..I completed the RHEL 5 + Xen instalaltion and am now being able to boot
into it (Dpm 0). Thanks for your suggestions.

So now the next step is to install some Guest OSes....Where do I get
paravirtualized guest OS images to run on top of RHEL5+ Xen.

(I read some where that only RHEL5, RHEL4.5 and FC are currently supported.)

The python-virtinst  RPM should be on one of the CDs along with the
virt-manager RPMs. Probably in a directory called Virtualization.

IIRC the ought to be present in both client & server images.
