Imagine you have a device mapper target which consists of 1..N disks (e.g. it's a multipath device, LUKS disk, whatever). Now, libvirt currently allows only the frontend (/dev/dm-1) in CGroups. However, this can make qemu fail [1] so we need to allow all the backend devices too. 1: https://bugzilla.redhat.com/show_bug.cgi?id=1557769#c22 Michal Privoznik (5): virlog: Don't log devmapper utils: Introduce virFileGetMPathTargets virfile: Introduce virFileMajMinToName qemu: Handle multipath devices properly news: Document multipath fix docs/news.xml | 10 ++++ libvirt.spec.in | 2 + src/libvirt_private.syms | 2 + src/qemu/qemu_cgroup.c | 43 +++++++++++++- src/qemu/qemu_domain.c | 58 +++++++++++++++++++ src/util/virfile.c | 143 +++++++++++++++++++++++++++++++++++++++++++++++ src/util/virfile.h | 7 +++ src/util/virlog.c | 23 ++++++++ 8 files changed, 285 insertions(+), 3 deletions(-) -- 2.16.1 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
