Public bug reported: qemu-pr-helper binary is part of the qemu-system-common package. When using this with machines having multipath devices like FC or iSCSI backed disks, libmpathpersist support is required for the persistent reservations to work.
> Linking qemu-pr-helper to libmpathpersist does not impede its usage on regular SCSI devices. Documentation: https://www.qemu.org/docs/master/system/pr- manager.html#multipath-devices-and-persistent-reservations To fix this we need to have the multipath-tools package to be installed during build. libudev is required as well, which I guess we already have as a build time dependency. On Fedora, they seem to have this enabled already: https://src.fedoraproject.org/rpms/qemu/blob/rawhide/f/qemu.spec#_553 (look for have_multipath) $ lsb_release -rd Description: Ubuntu 22.04.5 LTS Release: 22.04 I looked at the qemu's meson.build file, Multipath support is only needed for qemu-pr-helper and qemu-vmsr-helper, so it should not affect any other binaries of qemu package. https://github.com/qemu/qemu/blob/e82989544e38062beeeaad88c175afbeed0400f8/meson.build#L4552-L4561 ** Affects: qemu (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2117378 Title: qemu-pr-helper doesn't have multipath support To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/2117378/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
