Discussed here https://www.redhat.com/archives/libvir-list/2020-August/msg00921.html Comes down to glibc vs tirpc the linking at build time is wrong (uses the wrong version).

I can replicate this with libvirt v6.6.0 from git. 6.0 works from packaging v6.0.0 from git does work as well. There are two approaches now: #1 the intro of tirpc v6.0.0 configure: xdr: yes (CFLAGS='' LIBS='') vs v6.6.0 configure: xdr: yes (CFLAGS='-I/usr/include/tirpc' LIBS='-ltirpc') Since the xdr code that wraps data crashes and the use of libntirpc-dev (new transport-independent RPC library - development files) is new that might be the primary issue here. Also this [1] old thread triggers all the buzzwords matching this issue in one go which is a +1 on maybe being related. And there is [2] in v6.6 and we added libtirpc-dev to the build-deps (as it is now strictly required). configure: error: You must install the libtirpc >= 0.1.10 pkg-config module to compile libvirt We can't build without tirpc anymore. So I can't just disable+try. #2 just raw bisect the code and do something else until then Chances are this will identify [2] but we will see.

The host being libvirt starts to communicate with libvirt_lxc
in src/lxc/lxc_process.c:
monitor = virLXCMonitorNew(vm, cfg->stateDir, );
On the receiving side this then crashes
__GI_xdr_uint64_t is xdr_uint64_t is of glibc-2.31/sunrpc/xdr_intXX_t.c
Once the libvirt_lxc process exists
communication is via /run/libvirt/lxc/sl.sock
then on libvirtd break on
b virLXCMonitorNew
On the receiving end we see:
b virLXCControllerEventSendInit

[Bug 1892826] Re: autopkgtest breaks in groovy at 6.6.0-1ubuntu1 for smoke-lxc
2020-08-25 07:14:30.657+: 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: #0 0x in ??
