Hi, Dear all
I have a question, and need your help.
I want to output some log message to
"/var/log/libvirt/qemu/instance-xxxxxx" when guest kernel crashed, so I add
following the code:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
static int
qemuProcessHandleGuestPanic(qemuMonitorPtr mon ATTRIBUTE_UNUSED,
virDomainObjPtr vm,
void
*opaque) { ......
+ qemuDomainLogContextPtr logCtxt = NULL;
+ if (!(logCtxt = qemuDomainLogContextNew(driver, vm,
QEMU_DOMAIN_LOG_CONTEXT_MODE_START))){
+ VIR_WARN("Unable to open domainlog");
+ goto cleanup;
+ }
......
}
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
But this code cannot get the logCtxt,
logCtxt = qemuDomainLogContextNew(driver, vm,
QEMU_DOMAIN_LOG_CONTEXT_MODE_START) always return NULL, so I CANNOT write
message to log file.
Really Need your help, Thanks!
Thanks
Feng
