can libvirt.so use jemalloc to manage mem ?
HI, all
My daemon exists a libvirt API call:
virEventRegisterDefaultImpl();
once I called the virEventRegisterDefaultImpl() ,must be core ,the bt stack is:
(gdb) bt
#0 free (ptr=0x1) at include/jemalloc/internal/arena.h:652
#1 0x00007f57690a488a in virFree () from /lib64/libvirt.so.0
#2 0x00007f57690c3562 in virResetError () from /lib64/libvirt.so.0

set keep alive
Can anyone explain what is happening.
After call
virConnectOpen
virEventRegisterDefaultImpl()
call virConnectSetKeepAlive returns
VirtError(1): internal error: the caller doesn't
support keepalive protocol; perhaps it's missing
event loop implementation,
but the next call this sequence of commands returns success.
Why virConnectSetKeepAlive not work right the first time?

Where actually is the callback triggered?
Hi all,
Quick question:
When the hypervisor triggers a callback which is registered for generic
events, (assuming I'm connected through qemu+tcp) where exactly is the
callback triggered? On the hypervisor host or on my host?
Regards
Kadir

virConnectIsAlive
...onnection(virConnectPtr) has to reconnect, Before usr old virConnectPtr , I call virConnectIsAlive. but when I restart libvirtd , virConnectIsAlive return 1, and I continue other operate use the old virConnectPtr, program will receive signal pipe.
I use libvirt event. before any api use, I call virEventRegisterDefaultImpl, and run virEventRunDefaultImpl. then use virConnectIsAlive, when I restart libvirtd, virConnectIsAlive will return 0, I want know how to use virConnectIsAlive， if virConnectIsAlive use keep alive message, what default the interval and count.
Thanks

java binding
Hi all,
I'm trying to use the libvirt event system in order to notify the VM
status (VM boot, reboot, crash, etc.). I must use the java binding, so
I exposed some calls not present in "Libvirt-java" jna interface:
virEventRunDefaultImpl()
virEventRegisterDefaultImpl()
(and several costant).
In my java source I tried to intercept the event, using the
"Connection.domainEventRegisterAny( ... )" call , but the "answer"
was:
"this function is not supported by the connection driver: no event
support". No errors issued on the virEventR...
