Disconnected from qemu, keepalive timeout

[Nir Levy <nirl@xxxxxxxxxxxxxxxxx>]

Hello Guys,

Thanks for reading this,
I have compiled libvirt and qemu over fedora 22 for using debug information and no opt (“-g3 -O0”).
I am investigating the xml feature
  <qemu:commandline>

    <qemu:arg value='-trace'/>

    <qemu:arg value='events=/home/qemu_traced_symbols'/>

  </qemu:commandline>

 

qemu_traced_symbols includes all qemu traced symbols.

I have used:

catch syscall clone

set follow-fork-mode child

set detach-on-fork off

 

and debugged the child

so after libvirt start VM2 wanted to debug the parameters (cmd->args, which indeed includes -trace and  events=/home/qemu_traced_symbols

I have debugged the the child after spawning.

And returned for the parent (using gdb inferior 1)
for debugging the virCommandHandshakeWait (with the args)

but I keep getting

error: Disconnected from qemu:///system due to keepalive timeout

grep @ libvirt-1.2.21/ shows no code only change log.

Can you please help me resolve this issue?

How do those args are passed, is it via JSON?

Kind regards,

Nir Levy

SW Engineer
