Re: [ovirt-users] FQDN for vm creating with hosted-engine

by Yue, Cong

--- 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?

Used Network resources of host XY [97%] exceeded

by Ml Ml

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

snapshot deletion problem

by Demeter Tibor

------=_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?
