I was able to run guestfish with "-v" option, using a wrapper also for
guestfish itself:
"
#!/bin/bash
exec /usr/bin/guestfish.orig -v "$@"
"
The reason for the failure seems this one:
"
qemu-kvm.orig: error: failed to set MSR 0x38d to 0x0\nqemu-kvm.orig:
/builddir/build/BUILD/qemu-2.10.0/target/i386/kvm.c:1809: kvm_put_msrs:
Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.\nlibguestfs: error:
appliance closed the connection unexpectedly, see earlier error
messages\nlibguestfs: child_cleanup: 0x5614c38e4580: child process
died\nlibguestfs: sending SIGTERM to process 29457\nlibguestfs: error:
/usr/libexec/qemu-kvm killed by signal 6 (Aborted), see debug messages above
"
Any hint?
Based on full output (see below) inside the GUI, it seems that the
step "libguestfs:
finished testing qemu features" has a result of kind
-machine accel=kvm:tcg \\\n -cpu host \\\n -m 500 \\\n -no-reboot \\\n -rtc
driftfix=slew \\\n -no-hpet \\\n -global kvm-pit.lost_tick_policy=discard
and so possibly makes useless my wrapper for guestfish???
here full output into the GUI:
