I'm not sure where it's failing - running qemu under gdb results in it receiving a SIGHUP, after xl has claimed the domain has exited. Starting the domain as paused and attaching to it shows the memory as empty, and then unpausing the domain immediately exits it (despite gdb paused on the first instruction). Perhaps it's somewhere in Xen code? Though I don't really know how to debug Xen itself (xl dmesg doesn't show anything unusual). Maybe it's something better suited for a Xen dev to debug? > > There's no changes in 5.0-6 (compared to 5.0-5) which are related to xen. > However there is a significant change in the toolchain, I wonder if this > might be related..
