xen newbie questions

[Mogens Kjaer]

I'm trying to learn xen.

fc6 install, all updates except the kernel,
which is 2.6.18-1.2869.fc6xen (the machine
doesn't run the 2.6.19 kernel).

If I log in as root, I get the following:

I can run /usr/bin/virt-manager, but not
/usr/sbin/virt-manager:

# virt-manager
Traceback (most recent call last):
   File "/usr/share/virt-manager/virt-manager.py", line 56, in ?
     import gtk
ImportError: No module named gtk

With xm I get:

# xm
Traceback (most recent call last):
   File "/usr/sbin/xm", line 8, in ?
     from xen.xm import main
ImportError: No module named xen.xm

# rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}\n"|fgrep xen
kernel-xen-2.6.18-1.2869.fc6.i686
xen-devel-3.0.3-3.fc6.i386
xen-libs-3.0.3-3.fc6.i386
xen-3.0.3-3.fc6.i386

What am I missing?

Good luck! I'm not going to bother. I will wait until I can afford a new 
processor and then I will try KVM. I have VMware 4.5 anyhow, just to play 
around with the nifty idea.

Sorry, they've all gone to bed. Can't help :-(

You need to install the gtk2 RPMs:

yum install gtk2

If you have the space, might as well install all gtk2 stuff:

yum install gtk2*

It got you past the gtk issue.  xen.xm module is part of the xen RPM.
You have that installed, right?  If so, then there's something weird.
The module should be in /usr/lib[64]/python2.4/site-packages.  It's
looking for "/usr/lib[64]/python2.4/site-packages/xen/xm/main.pyc".

# ls -l /usr/lib/python2.4/site-packages/xen/xm/main.py
-rw-r--r-- 1 root root 44354 Jan 11 19:37 
/usr/lib/python2.4/site-packages/xen/xm/main.py
# rpm -qf /usr/lib/python2.4/site-packages/xen/xm/main.py
xen-3.0.3-3.fc6

It's there all right.

I've tried

strace -o/tmp/xm.strace xm

and I've put the output at:

ftp://ftp.crc.dk/pub/xen/xm.strace

It was a stupid mistake by me; I had a local python
installed in /usr/local/bin - required by some other
software.
