I'm trying to run virt-manager to connect to Xen. However its not possible to start the libvirt daemon.

When starting /usr/sbn/libvirtd via systemctl start libvirtd or by starting /usr/sbin/libvirtd via cmdline I get the error:

libvirtd[4289]: libvirtd: libxl_fork.c:353: sigchld_installhandler_core: \ Assertion `((void)"application must negotiate with libxl about SIGCHLD", \ !(sigchld_saved_action.sa_flags & SA_SIGINFO) && \  (sigchld_saved_action.sa_handler == SIG_DFL || \  sigchld_saved_action.sa_handler == SIG_IGN))' failed. 

Any hint what could be wrong?

I'm running Xen installed via apt-get install xen-hypervisor-4.9-amd64.

Distributor ID: Ubuntu Description:    Ubuntu 18.04.1 LTS Release:    18.04 Codename:   bionic 

/usr/sbin/libvirtd comes from:

Eu depurei mais e descobri que a afirmação vem de:

  (gdb) p /x sigchld_saved_action $3 = {__sigaction_handler = {sa_handler = 0x7fc5b5b1c400, sa_sigaction = 0x7fc5b5b1c400}, sa_mask = {__val = {0x0, 0xb, 0x7fc5ff51209d, 0x7fc5ff7308f0,        0xb, 0x1d, 0x5, 0x7fc5c5044ca0, 0x7fc594123d00, 0x7fc5c50448d0, 0x7fc5ff5120be, 0x7fc5ff774760, 0x557e03daa170, 0x7fc5b1eae730, 0x7fc594123d00,        0x7fc5b1eae680}}, sa_flags = 0x14000001, sa_restorer = 0x7fc5fec12890}    

Qual parece ser um manipulador sigchld_saved_action.sa_handler está dentro

  7fc5b5c1f000-7fc5b5e1f000 ---p 002a7000 08:12 1578012                    /usr/lib/virtualbox/VBoxRT.so    

que é de /usr/lib/virtualbox/vboxrt.so.

Movendo / usr / lib / virtualbox fora via sudo mv /usr/lib/virtualbox /usr/lib/virtualbox.bck Faz-me capaz de iniciar libvirtd .

 

I debugged further and found that the assertion comes from:

(gdb) p /x sigchld_saved_action $3 = {__sigaction_handler = {sa_handler = 0x7fc5b5b1c400, sa_sigaction = 0x7fc5b5b1c400}, sa_mask = {__val = {0x0, 0xb, 0x7fc5ff51209d, 0x7fc5ff7308f0,        0xb, 0x1d, 0x5, 0x7fc5c5044ca0, 0x7fc594123d00, 0x7fc5c50448d0, 0x7fc5ff5120be, 0x7fc5ff774760, 0x557e03daa170, 0x7fc5b1eae730, 0x7fc594123d00,        0x7fc5b1eae680}}, sa_flags = 0x14000001, sa_restorer = 0x7fc5fec12890} 

which seems to be a handler sigchld_saved_action.sa_handler is inside

7fc5b5c1f000-7fc5b5e1f000 ---p 002a7000 08:12 1578012                    /usr/lib/virtualbox/VBoxRT.so 

which is from /usr/lib/virtualbox/VBoxRT.so.

Moving /usr/lib/virtualbox away via sudo mv /usr/lib/virtualbox /usr/lib/virtualbox.bck makes me able to start libvirtd.
