Re: [Users] Obtain VM name from within VM?

I'm not familiar with this feature and I don't see any information about it in the Redhat RHEV documentation. All I've found is this: http://www.ovirt.org/Features/VMPayload That suggests I can use the API to set this up, but is this possible via the administrative UI instead? Could I do this in a creation-time VDSM hook? Thanks, -- Jonathan Daugherty Software Engineer Galois, Inc. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[Users] Obtain VM name from within VM?
Hi, I'm interested to know whether it is possible to obtain a VM's name from within a VM. In particular I'd like to obtain VM names from within Linux guests for the purpose of setting up dynamic DNS based on the VM name. I don't see the VM name in the output of dmidecode and there doesn't appear to be an entry in the ovirt guest API to obtain it. (In any case I can't run the ovirt guest agent on my VMs, so I'd like some other way to get it.)

[Users] Backup and restore procedure?
Greetings, I'm working on deploying oVirt for the first time and I need to know what needs to be backed up in order to be prepared for a system recovery. Is this documented? For the engine, so far I imagine I'd want to back up /etc and dump my postgres database; the restore procedure for both of those is trivial. For the nodes, other than /etc, I don't know what needs to be backed up or what the restore procedure is. (And backing up /etc just for this seems a bit ham-fisted.) What am I missing?

Okay, I'll answer it myself, for the google searchers of the future: This was caused by 1) not restarting libvirtd *after* disabling firewalld and 2) not realizing (understandably) that the error was from the migration *destination* host, not the source host, despite the fact that it was found in the source host's log and makes no mention of the other host. Libvirtd on the destination host was still attempting to use firewalld; restarting it resolved the problem. -- Jonathan Daugherty Software Engineer Galois, Inc. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[Users] oVirt and firewalld
Hi, I've just set up a new oVirt installation with two nodes. Both of the nodes have had 'firewalld' disabled. When I went to test VM migration, it failed, apparently due to this (from the vdsm log on the source node): error : virNetClientProgramDispatchError:174 : Error while building firewall: Some rules could not be created for interface vnet0: Failure to execute command '$EBT -t nat -N libvirt-J-vnet0' : 'DBusException org.freedesktop.DBus.Error.ServiceUnknown: The name org.fedoraproject.FirewallD1 was not provided by any .service filesCouldn't connect to FirewallD, it's probably not running.'. Is running firewalld a requirement for oVirt? Is it possible to avoid having oVirt attempt to manage my firewall rules?
