Description Fangge Jin 2015-07-27 06:08:12 EDT
Description of problem:
When setting keepalive_required=1, libvirtd will refuse all the clients even if the client supports keepalive.

Version-Release number of selected component :

How reproducible:

Steps to Reproduce:
1.Set keepalive_required=1 in libvirtd.conf on host A, restart libvirtd service.

2.Connect to the libvirtd of host A:
# virsh -c qemu+tcp://
error: failed to connect to the hypervisor
error: operation failed: keepalive support is required to connect

Actual results:
As step2, libvirtd refused the client connection.

Expected results:
As virsh client supports replying for server keepalives, it should connect successfully.

    rpc: Remove keepalive_required option
Comment 6 zhenfeng wang 2015-08-24 05:35:06 EDT
Verify this bug with libvirt-1.2.17-6.el7, could found the clear explanation that the keepalive_required option has been removed in libvirtd.conf, also found the corresponding code has been disabled, so we could verify this bug right now. 

# These configuration options are no longer used.  There is no way to
# restrict such clients from connecting since they first need to
# connect in order to ask for keepalive.
#keepalive_required = 1
#admin_keepalive_required = 1
