[libvirt-users] 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? -- Fl@sh
