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.
You are getting this from the 'virsh start $domain' command, right?
Can you please help me resolve this issue? How do those args are passed, is it via JSON?
For your use case you really want to disable the keepalive by using -k0 parameter for virsh, so it will become 'virsh -k0 start $domain'
