[Xen-users] More CentOS 5.2 & Xen 3.2.1 Compiling Questions!

Hi All,

So I have a Intel DQ35JO board, CentOS5.2 x86_64 and I''ve tried to
update Xen 3.1.2 to Xen 3.2.1 by using the method listed here:

http://wiki.xensource.com/xenwiki/VTdHowTo

Unfortunately, (other than the fact that xen-unstable.hg now points to
3.3 so I used xen-3.2-testing.hg), the kernel from the mercurial
repository of 2.6.18 is missing some modules that CentOS 5.2 has for
the Intel DQ35JO.  I can boot fine after compile &amp; installation of
the new kernel, but I''m missing modules that linux-2.6.18-xen.hg
doesn''t have which CentOS 5.2 kernels do have.  They are:

1. The pata_marvell module for the ATA ports.

2. The e1000e module (not the e1000).

3. The video driver for the Intel Q35 IGP.

I''m currently running kernel 2.6.18-92.1.6.el5xen and grabbed the SRPMS
for it.
(http://mirror.centos.org/centos/5.2/updates/SRPMS/kernel-2.6.18-92.1.6.el5.src.rpm)

After unpacking it, the directory structure looks like this in the
BUILD folder:

kernel-2.6.18/config

kernel-2.6.18/linux-2.6.18.x86_64

kernel-2.6.18/vanilla

kernel-2.6.18/xen

I''ve grabbed xen-3.2.1.tar.gz and I''m trying to follow
directions from
the following thread:

http://xen.markmail.org/message/mlo7cw7ydaj4gn6v

But I''m not sure how to properly make the TARBALL of CentOS''s
Xenified
kernel to feed to during the 3.2.1 compile (and the methods and hacks
to use your own kernel source vs. Xen''s), *and* enable the PCI-Device
Backend Driver for Intel VT-d support.  I think once I get past that
point, I''d be able to continue from all of the rest of the
documentation.  If I''m successful, I''d be more than happy to
create
RPM''s for CentOS 5.2 x86_64 for Xen 3.2.1 with VT-d support turned on
in the kernel.

Thanks in advance!

Don''t use the xen kernel from xen.org just the hypervisor.

Download the 3.2 SRPM from xen.org, download the 3.2.1 tarball,
put the 3.2.1 tarball into the SOURCES directory, edit the
3.2 spec file and change the version to 3.2.1 then do an
rpmbuild of the spec.

This will produce RPMs that you can then substitute the CentOS
ones with and it won''t compile the kernel just the hypervisor,
continue to use the CentOS supplied xen kernels with the
new hypervisor.

Re: [Xen-users] More CentOS 5.2 & Xen 3.2.1 Compiling Questions!

Hi Ross,

Thank you very much for the reply.  It makes sense!  So let me break
down the instructions:

1. rpm -i
http://bits.xensource.com/oss-xen/release/3.2.0/centos-5.1/xen-3.2.0-0xs.centos5.src.rpm
2&gt; /dev/null

2. cd /usr/src/redhat/SOURCES ; wget
http://bits.xensource.com/oss-xen/release/3.2.1/xen-3.2.1.tar.gz

3. vi ../SPECS/xen.spec

 i. Change "Version: 3.2.0" to "Version 3.2.1"

 ii. Change "Source0: xen-3.2.0.tar.gz" to "Source0:
xen-3.2.1.tar.gz"

 iii. Uncomment "# /usr/lib/xen/boot/hvmloader" to
"/usr/lib/xen/boot/hvmloader".
(noted from previous threads to avoid rpmbuild error of unpackaged file)

4. yum -y install transfig texi2html tetex-latex gtk2-devel
libaio-devel gnutls-devel (dependencies needed for rpmbuild of
xen.spec in CentOS)

5. cd /usr/src/redhat/SPECS ; rpmbuild -ba ./xen.spec

6. Grab some coffee...

... and come back to this:

+ cd xen-3.2.1

+ rm -rf /var/tmp/xen-3.2.1-0xs-root

+ exit 0

7. vi /etc/yum.conf and temporarily set "gpgcheck=0"
to "gpgcheck=1" since RPMs aren''t signed.

8. cd /usr/src/redhat/RPMS/x86_64 ; yum -y install
xen-3.2.1-0xs.x86_64.rpm xen-libs-3.2.1-0xs.x86_64.rpm
xen-devel-3.2.1-0xs.x86_64.rpm

9. vi /etc/yum.conf and set gpgcheck back to "gpgcheck=1".

Reboot.

xend won''t start now with the following in /var/log/xen/xend.log

I did a quick peek in /usr/lib64/python2.4/site-packages/xen and all
the Python tools looks to be correct with 3.2.1.

Any ideas?

Maybe you can try the packages released at www.halsign.com.

Yes, almost perfect setup, except, need to edit /boot/grub/grub.conf
and switch all /boot/xen-3.1... references to /boot/xen-3.2...
the errors you saw are what happens when the newer libraries try
to access the older hypervisor.

Re: [Xen-users] More CentOS 5.2 & Xen 3.2.1 Compiling Questions!

Hi Ross,

Bingo.  I skipped one of the most important parts!  ;)  I keep
forgetting that grub.conf isn''t automagically updated (which is a GOOD
thing).  Changed over to the proper one and Xen 3.2.1 is running
beautifully in CentOS 5.2 x86_64.

I enabled vtd=1 and have successfully done a PCI passthrough (pciback)
to a HVM domU (Windows XP) for a video capture card device which is on
the PCI Express bus.

Thank you VERY much, Ross!

Cheers,

Daniel

P.S. So the full instructions are for getting Xen 3.2.1 installed onto
a fresh copy of CentOS 5.2 (without existing Xen packages):

1. rpm -i
http://bits.xensource.com/oss-xen/release/3.2.0/centos-5.1/xen-3.2.0-0xs.centos5.src.rpm
2&gt; /dev/null

2. cd /usr/src/redhat/SOURCES ; wget
http://bits.xensource.com/oss-xen/release/3.2.1/xen-3.2.1.tar.gz

3. vi ../SPECS/xen.spec

 i. Change "Version: 3.2.0" to "Version 3.2.1"

 ii. Change "Source0: xen-3.2.0.tar.gz" to "Source0:
xen-3.2.1.tar.gz"

 iii. Uncomment "# /usr/lib/xen/boot/hvmloader" to
"/usr/lib/xen/boot/hvmloader".
(noted from previous threads to avoid rpmbuild error of unpackaged file)

4. yum -y install transfig texi2html tetex-latex gtk2-devel
libaio-devel gnutls-devel (dependencies needed for rpmbuild of
xen.spec in CentOS)

5. cd /usr/src/redhat/SPECS ; rpmbuild -ba ./xen.spec

6. Grab some coffee...

... and come back to this:

or "kernel /xen.gz-3.2 vtd=1 msi_irq_enable=1" (one of the
three depending if you want Intel VT-d and/or MSI/MSI-X enabled for
capable systems) and make sure "default=" is pointed to the
correct title. **Note: Double-check /boot/xen.gz-3.2 exists on your

11. Reboot.

Check Xen (xm dmesg) and see if you''re golden.

RE: [Xen-users] More CentOS 5.2 & Xen 3.2.1 Compiling Questions!

Hi Everyone,

 

I need Xen 3.2+ and have been following this thread. I already have Infiniband
bits and pieces added to the kernel and hence it seems I cannot use the RPMs. 
Lots of error like this appear during the RPM install (If anyone know how I can
get away with using the RPMs then please let me know):

WARNING:
/lib/modules/2.6.18-92.1.6.el5xen/updates/kernel/drivers/infiniband/ulp/srpt/ib_srpt.ko
needs unknown symbol scst_unregister_session

WARNING:
/lib/modules/2.6.18-92.1.6.el5xen/updates/kernel/drivers/infiniband/ulp/srpt/ib_srpt.ko
needs unknown symbol scst_rx_data

 

Am I best off reinstalling Centos without the virtualization option? (Current
install has Server and Virtualization options).

 

 Also it seems I might be better off using Centos 5.1 because my Raid utilities
wont work with 5.2. Is the following a sensible install process?:

Install Centos 5.1 with only Server option and 5.1 Raid Driver

Install Raid utilities

Yum Update Kernel and Install Kernel-Devel

Follow instructions below

Install Infiniband OFED tools to new Xen Kernel

Compile Kernel Again

Install DRBD and other apps I need.

 

Thanks,

 

Rob

Installing centos 5.1 without virtualization and then installing xen from
source is a good option.

RE: [Xen-users] More CentOS 5.2 & Xen 3.2.1 Compiling Questions!

Hello Daniel,

Do virt-manager and virt-install still work on your system with CentOS 5.2 &
Xen 3.2.1 together?

Installing CentOS 5.2 without the Xen packages leaves those off the system, but
when I upgrading to Xen 3.2.1 (or later) on a Centos 5.2 installed with the Xen
packages seems to put the ''xm'' commands in a broken state
("Permission denied" errors start to show up).

Do you install them separately after upgrading?

Thanks in advance,
Ed

Hi Ross,

Bingo.  I skipped one of the most important parts!  ;)  I keep forgetting that
grub.conf isn''t automagically updated (which is a GOOD thing).  Changed
over to the proper one and Xen 3.2.1 is running beautifully in CentOS 5.2
x86_64.

I enabled vtd=1 and have successfully done a PCI passthrough (pciback) to a HVM
domU (Windows XP) for a video capture card device which is on the PCI Express
bus.

Thank you VERY much, Ross!

Cheers,
Daniel

P.S. So the full instructions are for getting Xen 3.2.1 installed onto a fresh
copy of CentOS 5.2 (without existing Xen packages):

1. rpm -i
http://bits.xensource.com/oss-xen/release/3.2.0/centos-5.1/xen-3.2.0-0xs.centos5.src.rpm
2> /dev/null
2. cd /usr/src/redhat/SOURCES ; wget
http://bits.xensource.com/oss-xen/release/3.2.1/xen-3.2.1.tar.gz
3. vi ../SPECS/xen.spec
 i. Change "Version: 3.2.0" to "Version 3.2.1"
 ii. Change "Source0: xen-3.2.0.tar.gz" to "Source0:
xen-3.2.1.tar.gz"
 iii. Uncomment "# /usr/lib/xen/boot/hvmloader" to
"/usr/lib/xen/boot/hvmloader". (noted from previous threads to avoid
rpmbuild error of unpackaged file)
4. yum -y install transfig texi2html tetex-latex gtk2-devel libaio-devel
gnutls-devel (dependencies needed for rpmbuild of xen.spec in CentOS)
5. cd /usr/src/redhat/SPECS ; rpmbuild -ba ./xen.spec
6. Grab some coffee...

... and come back to this:

10. vi /etc/grub.conf and change the "kernel" line to "kernel

/xen.gz-3.2 vtd=1 msi_irq_enable=1" (one of the three depending if you want
Intel VT-d and/or MSI/MSI-X enabled for capable systems) and make sure
"default=" is pointed to the correct title. **Note: Double-check
/boot/xen.gz-3.2 exists on your system!
11. Reboot.

Check Xen (xm dmesg) and see if you''re golden.

12. Using yum, install virt-manager and/or virt-viewer to get all the CLI/GUI
utilities!

Cheers,
Daniel

I did a quick peek in /usr/lib64/python2.4/site-packages/xen

and all the Python tools looks to be correct with 3.2.1.



Any ideas?





Yes, almost perfect setup, except, need to edit /boot/grub/grub.conf

and switch all /boot/xen-3.1... references to /boot/xen-3.2...

the errors you saw are what happens when the newer libraries try

to access the older hypervisor.

RE: [Xen-users] More CentOS 5.2 & Xen 3.2.1 Compiling Questions!

# yum -y install xen-3.2.1-0xs.x86_64.rpm
xen-libs-3.2.1-0xs.x86_64.rpm xen-devel-3.2.1-0xs.x86_64.rpm
would install phyton-virtinst package (resolving
dependencies).

Virt-install would be in working shape.
Virt-manager - no

Hello Daniel, 

   

Do virt-manager and virt-install still
work on your system with CentOS 5.2 & Xen 3.2.1 together? 

   

Installing CentOS 5.2 without the Xen packages
leaves those off the system, but when I upgrading to Xen 3.2.1 (or later) on a
Centos 5.2 installed with the Xen packages seems to put the ‘xm’
commands in a broken state (“Permission denied” errors start to
show up). 

   

Do you install them separately after
upgrading? 

   

Thanks in advance, 

Ed

Hi Ross,



Bingo.  I skipped one of the most important parts!  ;)  I keep
forgetting that grub.conf isn''t automagically updated (which is a GOOD
thing).  Changed over to the proper one and Xen 3.2.1 is running
beautifully in CentOS 5.2 x86_64.



I enabled vtd=1 and have successfully done a PCI passthrough (pciback) to a HVM
domU (Windows XP) for a video capture card device which is on the PCI Express
bus.



Thank you VERY much, Ross!



Cheers,

Daniel



P.S. So the full instructions are for getting Xen 3.2.1 installed onto a fresh
copy of CentOS 5.2 (without existing Xen packages):



1. rpm -i
http://bits.xensource.com/oss-xen/release/3.2.0/centos-5.1/xen-3.2.0-0xs.centos5.src.rpm
2> /dev/null

2. cd
/usr/src/redhat/SOURCES ; wget
http://bits.xensource.com/oss-xen/release/3.2.1/xen-3.2.1.tar.gz

3. vi
../SPECS/xen.spec

 i. Change "Version: 3.2.0" to "Version 3.2.1"

 ii. Change "Source0: xen-3.2.0.tar.gz" to
"Source0:
xen-3.2.1.tar.gz"

 iii. Uncomment "# /usr/lib/xen/boot/hvmloader"
to "/usr/lib/xen/boot/hvmloader".
(noted from previous threads to avoid rpmbuild error of unpackaged file)

4. yum -y
install transfig texi2html tetex-latex gtk2-devel libaio-devel gnutls-devel
(dependencies needed for rpmbuild of xen.spec in CentOS)

5. cd
/usr/src/redhat/SPECS ; rpmbuild -ba ./xen.spec

6. Grab some coffee...



... and come back to this:

+ umask 022

+ cd /usr/src/redhat/BUILD

+ cd xen-3.2.1

+ rm -rf /var/tmp/xen-3.2.1-0xs-root

+ exit 0



7. vi
/etc/yum.conf and temporarily set "gpgcheck=0"
to "gpgcheck=1"
since RPMs aren''t signed.

8. cd
/usr/src/redhat/RPMS/x86_64 ; yum -y install xen-3.2.1-0xs.x86_64.rpm
xen-libs-3.2.1-0xs.x86_64.rpm xen-devel-3.2.1-0xs.x86_64.rpm

9. vi
/etc/yum.conf and set gpgcheck back to "gpgcheck=1".

10. vi
/etc/grub.conf and change the "kernel"
line to "kernel
/xen.gz-3.2" or "kernel /xen.gz-3.2 vtd=1"
or "kernel
/xen.gz-3.2 vtd=1 msi_irq_enable=1" (one of the three
depending if you want Intel VT-d and/or MSI/MSI-X enabled for capable systems)
and make sure "default=" is pointed to the correct title. **Note:
Double-check /boot/xen.gz-3.2 exists on your
system!

11. Reboot.



Check Xen (xm dmesg) and see if you''re golden.



12. Using yum, install virt-manager and/or virt-viewer to get all the CLI/GUI
utilities!



Cheers,

Daniel

  Yes, almost perfect setup, except, need to edit /boot/grub/grub.confand switch
all /boot/xen-3.1... references to /boot/xen-3.2...the errors you saw are what
happens when the newer libraries tryto access the older hypervisor.  -Ross
