libvirt 3.4.0
centos 7.4
Hi:
I want usr libvrit create vm to debug linux kernel. Previous , I usr qemu cmd(-gdb tcp::1234) directly. When I search on Internet, I found I can use libvrt xml configure kgdb.
<qemu:commandline>
<qemu:arg value='-gdb'/>
<qemu:arg value='tcp::1234'/>
</qemu:commandline>
But configure xml use kgdb is differnet on kernel boot. use qemu cmd, before I connect kernel use gdb , the kernel still not boot, When I use gdb connect the vm and put continue cmd on gdb, the kernel will start boot. But I usr libvirt xml configure kgdb, the kernel not stop, I want known that have some way I can use libvirt xml configure kgdb let kernel stop boot before I put continue on gdb?
Thanks
