RE: [Xen-users] Re: Xen 4.1.0 compiled from source on Debian Squeeze 6.0

["Ian Tobin" <itobin@xxxxxxxxxxxxx>]

I would compile it from source and use the menu options I suggested.

 

Do you have the xen fs mounted?

I've reinstalled Debian Squeeze and followed those exact commands, getting the same error:

root@node1:~# /etc/init.d/xencommons start

grep: /proc/xen/capabilities: No such file or directory

 

I don't think the kernel would be the issue in the first place, because I don't believe it's included in the source.

As quoted from the README: "Second, you need to acquire a suitable kernel for use in domain 0. If

possible you should use a kernel provided by your OS distributor."

I think make world also compiles a kernel which you don’t need in this case.

 

Have you tried

 

        cd /usr/src

 

        wget http://bits.xensource.com/oss-xen/release/4.1.0/xen-4.1.0.tar.gz

        tar xvf xen-4.1.0.tar.gz

 

        cd xen-4.1.0

        make xen

        make tools

        make stubdom

 

        cd dist/install

        cp -R * /

 

        cd usr/lib64     (if 64bit)

 

        cp -R * /usr/lib64    (if 64bit)

I'm simply following the README, "make world" and then "make install" afterwards.

Sorry I didn’t realise.  What steps are you doing to compile XEN?

Okay, I'm not compiling my own kernel though - I'm using the one in the Debian packages (2.6.32-5-xen-amd64) as suggested at http://wiki.xensource.com/xenwiki/XenDom0Kernels

Should I compile my own kernel instead?

When your in the make menuconfig screen, under Device Drivers select the same as mine, * is for static compile where M is to be used as a module.

 

 

 

Xm is based on python which is being depreciated.

Do you have any tutorial/hint on how to statically compile it?

And is there any reason it won't just work out of the box?
I've tried this on CentOs 5 too, but the same errors occur there..

 

And what exactly is the difference between xm and xl?

Statically compile the XEN stuff rather than using it as modules, I had the same grief as you but went away after doing that.

 

Also xm commands do not work for some reason but xl works fine.

Seems like part of my e-mail was lost, here is the rest...

--

 

At first, when running "xm list", I received this error:

"ImportError: No module named xen.xm"

 

I saw that /usr/lib/python2.6/site-packages/xen wasn't in sys.path of Python, so I symlinked it to /usr/lib/python2.6/xen - problem solved

 

Then I received this error:

Error: Unable to connect to xend: No such file or directory. Is xend running?

 

So I try starting xend:

xencommons should be started first.

 

So I try starting xencommons:

grep: /proc/xen/capabilities: No such file or directory

 

A thread on this mailing list suggested I added "none /proc/xen xenfs defaults 0 0" to /etc/fstab

I've done so, rebooted, but the issue persisted.

 

Another thread suggested I ran 'insmod xen-evtchn' and 'modprobe xen-evtchn', which gave me this error:

FATAL: Error inserting xen_evtchn (/lib/modules/2.6.32-5-xen-amd64/kernel/drivers/xen/xen-evtchn.ko): No such device

 

And now I'm rather stuck. What am I doing wrong?

I installed Debian Squeeze 6.0 on a server and am now trying to install Xen 4.1.0 on it (compiled from source, since the packages don't include Remus support).

Here are the steps I did to install it and get around several errors.

 

1) Installed Debian Squeeze 6.0 with default options and software RAID 1

2) Installed the dom0 kernel for Debian as shown at http://wiki.xensource.com/xenwiki/XenDom0Kernels

3) Rebooted into the kernel and made sure it was running:

Linux node1 2.6.32-5-xen-amd64 #1 SMP Thu May 19 01:16:47 UTC 2011 x86_64 GNU/Linux

 

4) Installed the requirements for compiling:

apt-get install zlib1g-dev python-dev libncurses-dev uuid-dev python-dev libncurses-dev libssl-dev xorg-dev uuid-dev build-essential gcc g++ gettext bcc iasl latex2rtf-doc gcc g++ build-essential 

 

5) Downloaded the 4.1.0 source, untarred it and ran "make world"

6) No errors except a warning about latex for documentation, so I ran "make install"

7) Rebooted again

 

At first, when running "xm list", I received this error:
