Hi, a few more details would help - ACS version, libvirt/qemu version, etc.
Have you followed all the steps on http://docs.cloudstack.apache.org/en/latest/installguide/hypervisor/kvm.html (this is 4.14 version guide) - i.e. libvirt configuration, selinux disabled/permissive, firewall (stop it while testing), setting host's fqdn, confirm you can telnet from the KVM host to the mgmt server to port 8250 (agent initiates this connections when started) - also confirm ssh access works from mgmt to agent, etc. Regards, On Wed, 24 Jun 2020 at 03:27, Practical XenServer < [email protected]> wrote: > When attempting to add my first host to my CS management server > (172.16.0.4) > I get this message in /var/log/cloudstack/management/management-server.log: > > 2020-06-24 01:11:43,127 WARN [c.c.r.ResourceManagerImpl] > (qtp119358627-14:ctx-ef5277d6 ctx-0125110f) (logid:964a6eef) Unable to find > the server resources at http://172.16.0.6 > 2020-06-24 01:11:43,127 INFO [c.c.u.e.CSExceptionErrorCode] > (qtp119358627-14:ctx-ef5277d6 ctx-0125110f) (logid:964a6eef) Could not find > exception: com.cloud.exception.DiscoveryException in error code list for > exceptions > 2020-06-24 01:11:43,128 WARN [o.a.c.a.c.a.h.AddHostCmd] > (qtp119358627-14:ctx-ef5277d6 ctx-0125110f) (logid:964a6eef) Exception: > com.cloud.exception.DiscoveryException: Unable to add the host > at > > com.cloud.resource.ResourceManagerImpl.discoverHostsFull(ResourceManagerImpl.java:822) > > Meanwhile: On the host that I'm trying to add (172.16.0.6)... > > 2020-06-23 21:47:55,009 INFO [cloud.agent.Agent] (Agent-Handler-2:null) > (logid:) Connected to the host: 172.16.0.4 > 2020-06-23 21:47:55,040 INFO [kvm.storage.LibvirtStorageAdaptor] > (Agent-Handler-1:null) (logid:) Attempting to create storage pool > 3d86e1d3-b8c5-47b3-96c8-c37d3064e9e4 (Filesystem) in libvirt > 2020-06-23 21:47:55,041 ERROR [kvm.resource.LibvirtConnection] > (Agent-Handler-1:null) (logid:) Connection with libvirtd is broken: invalid > connection pointer in virConnectGetVersion > 2020-06-23 21:47:55,042 INFO [kvm.storage.LibvirtStorageAdaptor] > (Agent-Handler-1:null) (logid:) Found existing defined storage pool > 3d86e1d3-b8c5-47b3-96c8-c37d3064e9e4, using it. > 2020-06-23 21:47:55,042 INFO [kvm.storage.LibvirtStorageAdaptor] > (Agent-Handler-1:null) (logid:) Trying to fetch storage pool > 3d86e1d3-b8c5-47b3-96c8-c37d3064e9e4 from libvirt > 2020-06-23 21:47:55,045 INFO [kvm.storage.LibvirtStorageAdaptor] > (Agent-Handler-1:null) (logid:) Attempting to create storage pool > 3d86e1d3-b8c5-47b3-96c8-c37d3064e9e4 (Filesystem) in libvirt > 2020-06-23 21:47:55,045 INFO [kvm.storage.LibvirtStorageAdaptor] > (Agent-Handler-1:null) (logid:) Found existing defined storage pool > 3d86e1d3-b8c5-47b3-96c8-c37d3064e9e4, using it. > 2020-06-23 21:47:55,046 INFO [kvm.storage.LibvirtStorageAdaptor] > (Agent-Handler-1:null) (logid:) Trying to fetch storage pool > 3d86e1d3-b8c5-47b3-96c8-c37d3064e9e4 from libvirt > 2020-06-23 21:47:55,049 WARN [cloud.agent.Agent] (Agent-Handler-1:null) > (logid:) Unable to send reques: null > 2020-06-23 21:47:55,147 INFO [cloud.agent.Agent] (Agent-Handler-2:null) > (logid:) Connected to the host: 172.16.0.4 > 2020-06-23 21:47:55,291 INFO [cloud.agent.Agent] (Agent-Handler-2:null) > (logid:) Connected to the host: 172.16.0.4 > 2020-06-23 21:47:55,444 INFO [cloud.agent.Agent] (Agent-Handler-2:null) > (logid:) Connected to the host: 172.16.0.4 > > On a hunch: I verified that libvirtd is listening on the host that I'm > trying to add (172.16.0.6)... > > [root@vmh-1 ~]# netstat -tanp | grep virt > tcp 0 0 0.0.0.0:16514 0.0.0.0:* LISTEN > 1654/libvirtd > tcp6 0 0 :::16514 :::* LISTEN > 1654/libvirtd > > Would somebody please be so kind as to tell me what all of that means - Why > can't I add hosts to this new management server? > > TIA, > Eric Pretorious > Portland, Oregon > -- Andrija Panić
