If you were trying to launch more than 7 DomU's, you might have hit the problem I did, which seems to be recently fixed: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=810472 https://lkml.org/lkml/2015/12/16/455 Symptom was: libxl: error: libxl_xshelp.c:134:libxl__xs_get_dompath: failed to get dompath for 8: Bad file descriptor I haven't verified that this patch went into kernel-4.3.5-200.fc22.x86_64 in -testing, but it works for me when 4.3.4 caused all the xl tools to fail on creation of Dom #8. 4.3.3-4 only seem to work for seven Dom's or fewer. -Bill -- Bill McGonigle, Owner BFC Computing, LLC http://bfccomputing.com/ Telephone: +1.855.SW.LIBRE Email, IM, VOIP: bill@xxxxxxxxxxxxxxxx VCard: http://bfccomputing.com/vcard/bill.vcf Social networks: bill_mcgonigle/bill.mcgonigle -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
