1.how libvirt communicate with qemu?
For starters, before diving into code, I'm learning it this way, by tracing all the
commands(let it be Qemu's QMP or others) virsh is calling:
Place the below log filters in /etc/libvirt/libvirtd.conf.
----
log_filters="1:libvirt 1:qemu_monitor 1:util 1:qemu"
log_outputs="1:file:/var/log/libvirt/libvirtd.log"
----
And, monitor /var/log/libvirt/libvirtd.log for all the calls libvirt is making.
For your other questions, I'll let more qualified people answer it.
/kashyap
call qemu'lib or open special device/socket?
2. i do not find the implement of function qemuAgentOpen---->qemuAgentInitialize().
i also search qemu-kvm source
3. qemuListAllDomains is the function which corespond to virsh-list. please explain
this function .
virDomainList(conn, driver->domains.objs, domains, flags);
i) it seems driver->domains.objs have gotten all dmains. so when and where
driver->domains.objs is assigned.
ii)and what is conn,and its definition?
thanks.
