You'll also need : diff --git a/src/qemu/test_libvirtd_qemu.aug.in b/src/qemu/test_libvirtd_qemu.aug.in index 688e5b9fda..b94b5349c4 100644 --- a/src/qemu/test_libvirtd_qemu.aug.in +++ b/src/qemu/test_libvirtd_qemu.aug.in @@ -60,6 +60,7 @@ module Test_libvirtd_qemu = { "8" = "/dev/kqemu" } { "9" = "/dev/rtc" } { "10" = "/dev/hpet" } + { "11" = "/dev/sev" } } { "save_image_format" = "raw" } { "dump_image_format" = "raw" } Not everyone has that augeas package installed and thus fail to run the 'check-augeas-remote'... I think that's all that's necessary - cgroups and devices being added is perhaps something Daniel knows a bit more about... John
