Description Demetri Mouratis 2006-05-04 16:28:40 UTC

Description of problem:

Xm complains with Error Creating Domain when invoked on fresh install of FC5
domU running on Xen/FC5 domO.

# uname -a
Linux db4.rnmd.net 2.6.16-1.2107_FC5xen0 #1 SMP Tue May 2 19:36:56 EDT 2006 i686
i686 i386 GNU/Linux

# xenguest-install.py -n xendomain1 -f /home/xen/xendomain1 -s 25 -r 384 -l
http://ops1.rnmd.net/fedora/core/5/i386/os -x
ks=http://ops1.rnmd.net/kickstart/cfgs/ks-fedora-core-5-xen-guest.cfg

If your install has exited, you can restart your guest by running
'xm create -c xendomain1'.  Otherwise, you can reconnect to the console
by running 'xm console xendomain1'

[root@db4 ~]# xm create -c xendomain1
Using config file "/etc/xen/xendomain1".
Going to boot Fedora Core (2.6.15-1.2054_FC5smp)
  kernel: /vmlinuz-2.6.15-1.2054_FC5smp
  initrd: /initrd-2.6.15-1.2054_FC5smp.img
Error: Error creating domain: (22, 'Invalid argument')


Version-Release number of selected component (if applicable):


How reproducible:

(Almost) every time.  I got the process to work on one or two domains before it
starting crashing each time.

Steps to Reproduce:
1.  Install FC5
2.  Install Xen kernel
3.  Reboot into Xen kernel
4.  Run xenguest-install.py
5.  xm create -c newdomain
  
Actual results:

Going to boot Fedora Core (2.6.15-1.2054_FC5smp)
  kernel: /vmlinuz-2.6.15-1.2054_FC5smp
  initrd: /initrd-2.6.15-1.2054_FC5smp.img
Error: Error creating domain: (22, 'Invalid argument')

Expected results:

New domain boots successfully.

Additional info:

Seems to have something to do with PAE which is enabled both in the BIOS and in
the FC5 Xen dom0 kernel.

Comment 1 Jeremy Katz 2006-05-23 19:04:24 UTC

Can you provide the contents of /sys/hypervisor/properties/capabilities and xm
dmesg?

Comment 2 Demetri Mouratis 2006-05-23 22:28:20 UTC

Hi Jeremy,

I don't see a /sys/hypervisor directory at all.  Is this useful:

[root@localhost ~]# cat /proc/xen/capabilities
control_d

Here's xm dmesg output:

Comment 3 Jeremy Katz 2006-05-24 14:38:38 UTC

Can you try with the newer xen0 kernel (which should be in -updates now I believe)

Comment 4 Demetri Mouratis 2006-05-24 16:00:24 UTC

Hi Jeremy,

I've done the patching and now have a related but new problem:

Thanks.
