My bad, it actually seems that your patch fixed my issue after I manually removed
the domain XML file that was stuck in /var/run. Nevertheless, it seems that the
issue when virt-manager exited preamturely could be caused by something else:
2012-02-05 15:39:28.395+0000: 29540: error : virNetSocketReadWire:999 : End of file while reading data: Input/output error

Hmm, this patch does not seem to fix my issue. See the both xml files in the attachment.On Sat, Feb 4, 2012 at 4:10 PM, Eric Blake <eblake@xxxxxxxxxx> wrote:
Commit b170eb99 introduced a bug: domains that had an explicit
<seclabel type='none'/> when started would not be reparsed if
libvirtd restarted. It turns out that our testsuite was not
exercising this because it never tried anything but inactive
parsing. Additionally, the live XML for such a domain failed
to re-validate. Applying just the tests/ portion of this patch
will expose the bugs that are fixed by the other two files.
* docs/schemas/domaincommon.rng (seclabel): Allow relabel under
type='none'.
* src/conf/domain_conf.c (virSecurityLabelDefParseXML): Per RNG,
presence of <seclabel> with no type implies dynamic. Don't
require sub-elements for type='none'.
* tests/qemuxml2xmltest.c (mymain): Add test.
* tests/qemuxml2argvtest.c (mymain): Likewise.
* tests/qemuxml2argvdata/qemuxml2argv-seclabel-none.xml: Add file.
* tests/qemuxml2argvdata/qemuxml2argv-seclabel-none.args: Add file.
