Description WSchleicher 2012-03-26 13:06:35 EDT
Description of problem:
error: unable to open stream for '(null)': Bad address
-> Unable to install pv guest (sl 6.2) on fedora domain0 (fedora 17 beta rc2)

Version-Release number of selected component (if applicable):
python-virtinst 0.600.1-1.fc17
kernel-PAE 3.3.0-5.fc17
xen 4.1.2-13.fc17

How reproducible:
- installing current fedora 17 (alpha, beta)
- installing xen
- rebooting in xen environment
- ensure that xen domain 0 is running (xl list) 0.5 from 2 GB reserved for dom0
- trying to install guest (domU) from network location

-> virt-install --connect xen:/// -n server_xen_232 -f /virtual/xen/server_xen_232.img -s 6.0 -r 512 --vcpus=1 --paravirt --uuid=00000192-0168-0000-0206-001921680232 -l --virt-type=xen --os-type=linux --os-variant=rhel6 -x "ks= i686 ip= netmask= gateway= dns= console=hvc0 earlyprintk=xen" --graphics none --debug

--> Connected to domain server_xen_232
--> Escape character is ...
--> error: unable to open stream for '(null)': Bad address

Steps to Reproduce:
see above
Actual results:
Installation stops (xml file is created) and reports errormessage as listed above. Domain installation is reported to be in progress... but furthermore there's no console connection possible.

Expected results:
Started guest should continue download network (xen)bootimage and installing rpms.

Additional info:
Same procedure works fine with fedora 15+16.

Not sure if this is a python-virtinst package problem only or a xen error in general!

Hmm, looks like libvirt is generating console XML like:

    <console type='pty'>
      <target type='xen' port='0'/>

There should be a pty path in there. That error message:

    error: Unable to open stream for '(null)': Bad address

Is coming from virsh console. So this is a libvirt issue

Thanks for additional info and bug redirection.

Today, I installed 17-Beta.RC4 which includes latest "libvirt-0.9.11-1.fc17.i686" and still faced the same problem. Seems that from first Fedora 17-TC libvirt does not play together with python-virtinst tool.

Meanwhile I used xen old deployment style (xl create -c domu.cfg) with creates a working domU image but does not include 'smart configuration switches' as offered by python-virtinst (xml).

Hopefully we'll see a working solution when Fedora 17 Final is released.

If current 17.RC4 will become GOLD/FINAL release the reported problem still exists...

No sure if fedora distribution is a suitable choice when it comes to xen as bare metal hypervisor. B.t.w., after installing xen packages, fedora's bootloader configuration (grub2.cfg / grub-install) ist not modified to boot in xen-environment.

'Problem' solved, xenconsoled was not running... daemon had to be started by hand
