Invalid configuration unexpected EOF when using -x

[Ray Van Dolson]

Hi all;

Trying to deploy a CentOS 5 domU under RHEL 5.3 64-bit and am running
into the following error:

virDomainCreateLinux() failed POST operation failed: (xend.err 'Invalid configuration unexpected EOF')
  Domain installation may not have been
   successful.  If it was, you can restart your domain
   by running 'virsh start cobbler'; otherwise, please
   restart your installation.

    --os-type=linux -d

The error appears to be triggered by my kickstart URL location which
includes ampersands and such -- despite the fact that I am include
quotes around the entire argument.

The debug output indicates that the XML is being written with the
ampersand changed into &.

If I change my kickstart location to a URL without the GET variables,
everything works fine.

Bug?  Expected behavior?  Workaround?  Perhaps this is an issue in
virt-install and wouldn't happen if I crafted the XML file myself?

Try single quotes or use back slashes to escape the ampersands

Pretty sure we fixed bugs in this area in 5.3: run the command with
--debug and see if the generated output has & in it.

I think in this case it is actually xend that is choking, which I don't
know any workaround for.

Yep, did run with --debug (-d) and the XML output has & in it.  I
haven't yet tried the single quote option as a workaround however.

Here is the cmdline generated (per debug output):

<cmdline>updates=http://yummie.esri.com/updates/updates-el5.1.img ks=http://yummie/ks/ks.php?arch=x86_64&distro=centos&major=5&minor=... method=http://yummie.esri.com/mrepo/centos5-x86_64/os/</cmdline>

So xend should be able to handle &amp; ?  Or, if my <cmdline> had &
instead of &amp; would xend be able to handle that?

I will try -- but curious if xend is supposed to work in either case.

Thanks,
Ray

Argh, sorry, I didn't read your first message clearly.

The & -> &amp; replacement is necessary for XML, so it's only needed for
talking to libvirt. That '&amp;' should be getting converted back to
plain & when passed off to xen. I think xen is just choking on the plain
'&'.

Try running the virtinst command with LIBVIRT_DEBUG=1 and see if there
is a generated sexpr printed (like you get with xm list --long).
