2020-08-25 07:14:30.657+0000: 264543: debug :
virFileFindResourceFull:1768 : Resolved 'libvirt_lxc' to
'/usr/lib/libvirt/libvirt_lxc'
>From package:
libvirt-daemon: /usr/lib/libvirt/libvirt_lxc
The following should be enough for debug:
$ sudo apt install libvirt-daemon-system-dbgsym libvirt-daemon-dbgsym
libvirt-daemon-driver-lxc-dbgsym
debug : virCommandRunAsync:2618 : About to run
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin
LIBVIRT_DEBUG=1 LIBVIRT_LOG_OUTPUTS=1:stderr /usr/lib/libvirt/libvirt_lxc
--name sl --console 24 --security=apparmor --handshake 30
...
To have the correct env set up we need to stop libvirt (via gdb) just
when it would start the lxc helper.
break on
virCommandRunAsync
and then on
virLXCProcessConnectMonitor
At this point we have the helper running
265197 /usr/lib/libvirt/libvirt_lxc --name sl --console 25 --security=apparmor
--handshake 30
The backtrace on the crash is this:
