(It does the latter quite > a lot.) >=20 Just to be sure, this part of the bisector report: branch xen-unstable xen branch xen-unstable job test-amd64-amd64-xl-win7-amd64 test windows-install means that the test that failed was 'job test-amd64-amd64-xl-win7-amd64' (and, specifically, during 'windows-install' phase), right? I'm asking because I actually found a bug in that change, _but_ it only comes into play if the SEDF scheduler is being used. In fact, this test also fails: http://www.chiark.greenend.org.uk/~xensrcts/logs/13053/test-amd64-amd64-xl-= sedf/info.html and it does by saying this: 2012-06-16 07:37:47 Z executing ssh ... root@10.80.248.105 xl create /etc/x= en/debian.guest.osstest.cfg libxl: error: libxl.c:3619:sched_sedf_domain_set: setting domain sched sedf= : Invalid argument libxl: error: libxl_create.c:710:domcreate_bootloader_done: cannot (re-)bui= ld domain: -3 Parsing config from /etc/xen/debian.guest.osstest.cfg Which is actually related to my patch, and for which I already have a fix ready. OTOH, I really don't see how that patch might cause that HVM windows domain to die, given the log for 'test-amd64-amd64-xl-sedf' says this: Parsing config from /etc/xen/win.guest.osstest.cfg Daemon running with PID 2642 Which seems to mean, at least to me, that the check happened without causing any issues (as it, conversely, does when SEDF is the scheduler). Anyway, I'll send the patch for the SEDF case and try to reproduce the bug for the credit+Win7+HVM case.
