Re: [ovirt-users] FQDN for vm creating with hosted-engine
by Yue, Cong 18 Dec '14

18 Dec '14

--- FQDN or fully qualified domain name means that you have to reserve in your DNS a name corresponding to IP received by HE VM from DHCP. IP address should be reserved for the VM at DHCP. I advise not to use manual IP to FQDN at your host, as this will lead to many confusions, especially when you'll have more than a single host machine, but you always can configure at your /etc/hosts file the FQDN corresponding to IP address given to HE VM. --- Thanks for the explanation. Now I understand what FQDN is for Ovirt. Is there any problem if I do not use the naming convention like aaa.bbb.ccc, but only aaa? Also I am some confused for the above explanation. Here it said the IP for VM is better to be got from DHCP rather than manual IP. If so, do this mean I need to change all /etc/hosts file of all virt nodes to update the IP for the FQDN for engine VM? What is the confusions if I use manual IP rather than DHCP for engine VM?

Hello List, one of my ovirt Guests seems to loose its Network connection. I can still see some traffic on the console tough. In the Logs i get: 2014-Dez-04, 13:09 Used Network resources of host <myhostname-here> [97%] exceeded defined threshold [95%]. Is this the reason? Where can i change or disable this feature? Thanks, Mario

Too much memory used in hosts

This is a multipart message in MIME format. ------=_NextPart_000_000C_01D01ABB.0EE8F8E0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Dear Ovirt users, I am new to ovirt. I have installed the Ovirt hosted setup on two machines running glusterfs. It has been working ok. I now have about 6 virtual machines in my cluster. The problem that I am having is; when I shutdown all the machines on one host, the memory is not freed. I migrated all the VMs to one Host and left the with 0, but still the memory is displayed at 89%. When I do a top on the same Host, I only see the vdsmd using 16%. I do not see any particular errors in any of the log files either. Would appreciate it if anybody could share their knowledge on the matter. Has it happened to anyone?

Hello! 1 engine- not hosted FC 19 + ovirt 3.5 ; 3 nodes - F20 and ovirt 3.5 patternfly due to high vdsm memory usage. All theree nodes serves as glusterfs server - 3 replicated bricks. After putting DC in maintenance - all VM shutdown, storages in maintenance (ISO, Data, Export) , stop gluster volume and finally hosts in maintenance , runned "yum update" on all nodes, reboot them, "Confirm host has been rebooted" but trying to activate them raise "Gluster command [<UNKNOWN>] failed on server....." and hosts goes in non operational. vdsm log goes like: Thread-15::ERROR::2014-12-18 10:17:53,439::__init__::493::jsonrpc.JsonRpcServer::(_serveRequest) Internal server error Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/yajsonrpc/__init__.py", line 488, in _serveRequest res = method(**params) File "/usr/share/vdsm/rpc/Bridge.py", line 264, in _dynamicMethod result = fn(*methodArgs) File "/usr/share/vdsm/gluster/apiwrapper.py", line 79, in list return self._gluster.hostsList() File "/usr/share/vdsm/gluster/api.py", line 54, in wrapper rv = func(*args, **kwargs) File "/usr/share/vdsm/gluster/api.py", line 251, in hostsList return {'hosts': self.svdsmProxy.glusterPeerStatus()} File "/usr/share/vdsm/supervdsm.py", line 50, in __call__ return callMethod() File "/usr/share/vdsm/supervdsm.py", line 48, in <lambda> **kwargs) File "<string>", line 2, in glusterPeerStatus File "/usr/lib64/python2.7/multiprocessing/managers.py", line 773, in _callmethod raise convert_to_error(kind, result) GlusterCmdExecFailedException: Command execution failed error: Connection failed.

------=_Part_6177275_580934676.1418884459164 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi, After a live VM storage movement process Ovirt has been created two snapshots. (I have two disks in vm) I have powered off and delete this snapshots. (It was long,long time) Before the process I had 830 GB of free spaces, but after deletion it hasn't freed up spaces, inversely, at this moment I have only 530 GB ! I checked the filesystem and I found, the VM disk images got an "_MERGE" versions. So it is duplicated. On the "tasks" remained two tasks. It is big problem for me because I have a lot of similara vm-s, and I don't have space enougth. I need to release this spaces . Also, the vm is working fine. How can I delete these extra files? Why doesn't delete the engine selfmade?
