(In reply to Jürgen Weber from comment #0)
I cannot reproduce it:

# freebsd-version -kru
15.1-RELEASE-p2
15.1-RELEASE-p2
15.1-RELEASE-p2
# ldd /usr/sbin/bhyve | grep libuvmem
        libuvmem.so.1 => /usr/lib/libuvmem.so.1 (0x25f3742bd000)
# vm li
NAME          DATASTORE  LOADER  CPU  MEMORY  VNC           AUTO     STATE
test-chr      default    uefi    2    1G      -             No       Running (27931)
test-fbsd151  default    uefi    2    4G      -             No       Stopped
test-vm02     default    uefi    2    4G      0.0.0.0:5900  Yes [1]  Running (14339)

I think /usr/lib/libuvmem.so.1 somehow lost on your system. Try to restore it.

I got libuvmem.* from another system, VMs start again.

I updated more systems, libuvmem.* are still there. On one they are missing, a 14.4.8 VM (freebsd-upgrade).

The system I met the bug first, is a quite old freebsd-upgrade system, updated very often, starting with 12.0, I believe.
Comment 3 Oleksandr Kryvulia 2026-07-31 10:39:51 UTC 
libuvmem(3) was introduced in 15.1, that's why it is missing in 14.4.
