Odd messages on new node/hosted engine
by Chris Adams 23 Jul '14

23 Jul '14

I built a new node+hosted engine setup, using up-to-date 6.5 and oVirt 3.4.3-RC. I see some odd messages, that I think are probably related: - In the hosted engine UI, I have an Alert that says "Failed to verify Power Management configuration for Host hosted_engine_1." - On the node, I get the following chunk repeated every 10 seconds in /var/log/messages: Jul 16 14:34:19 node0 kernel: device-mapper: table: 253:2: multipath: error getting device Jul 16 14:34:19 node0 kernel: device-mapper: ioctl: error adding target to table Jul 16 14:34:19 node0 kernel: device-mapper: table: 253:2: multipath: error getting device Jul 16 14:34:19 node0 kernel: device-mapper: ioctl: error adding target to table Jul 16 14:34:19 node0 multipathd: dm-2: remove map (uevent) Jul 16 14:34:19 node0 multipathd: dm-2: devmap not registered, can't remove Jul 16 14:34:19 node0 cpuspeed: Disabling performance cpu frequency scaling governor Jul 16 14:34:19 node0 multipathd: dm-2: remove map (uevent) Jul 16 14:34:19 node0 multipathd: dm-2: devmap not registered, can't remove Jul 16 14:34:19 node0 multipathd: dm-2: remove map (uevent) Jul 16 14:34:19 node0 multipathd: dm-2: devmap not registered, can't remove Jul 16 14:34:19 node0 multipathd: dm-2: remove map (uevent) Jul 16 14:34:19 node0 multipathd: dm-2: devmap not registered, can't remove Jul 16 14:34:20 node0 cpuspeed: Enabling performance cpu frequency scaling governor There is no dm-2; the system is installed on 2 SAS drives, mirrored using Linux md RAID1, using LVM (dm-0 is the root filesystem and dm-1 is swap).

status disks locked
by Andy Michielsen 23 Jul '14

23 Jul '14

Hello, I have a vm in my ovirt setup which has it's disks locked after I wanted to take a snapshot. I have a separate node and an engine and already rebooted them both but it still keeps on telling me it's disks are locked. Where does this info come from and what can I do to rectify the situation. Kind regards.

user permissions
by Jorick Astrego 23 Jul '14

23 Jul '14

Hi, In our 3.4.3 environment I started adding external users (it is connected to a freeipa server) and I'm having some problems setting the correct permissions. When I give all user roles to a user, I cannot create a vm and get an error "User is not authorized to perform this action". I tried setting it on the system level, DC level and cluster level. I needed to give this user an administrator role with only exactly the same vm and disk permissions (nothing extra) and things work ok, but he can now login to the admin portal. So I blocked it with a .htaccess which is not the prettiest solution. Am I doing things wrong? Also the user disappeared from the "System permissions" overview but can still login, which is a bit weird. Kind regards, Jorick Astrego Netbulae

--531777075-1929634716-1405211736=:9870 Content-Type: text/plain; charset=us-ascii Greetings, Been trying for a long time to install OVIRT 3.4.2 in a single 2U Server, however OVIRT 3.4 requires 2 physical hosts. Today tried to install OVIRT 3.5 nightly package, however All in one files are missing to install OVIRT 3.5 in a single physical node. Any help please?

Snapshots auto generated for live Storage
by André Freitas 23 Jul '14

23 Jul '14

Hi, after i had successfully migrated the disks to a different nfs datastore, i now have a vm with 3 snapshots: 1 current with the description "Active VM" and 2 more with the description "Auto-generated for Live Storage". For what i have been reading online, i can only delete snapshots with the vm offline. is this true? Second, should i commit the live storage snapshots before i delete them or its safe to delete them without commit?

Backup solutions for Ovirt
by saurabh 22 Jul '14

22 Jul '14

Hi All, I am using Ovirt for my QA environment almost 15 virtual servers, and it is working as expected. The only thing I am worried about is the backup solutions in case of failure or system crash. I tried looking into the LVM structure that is created by Ovirt but it seems a bit complex. Please let me know the proper solution (if there is any) for backing up my environment in case of failure.
