iSCSI question... LUNS->Targets balnk
by Alan Murrell 16 Aug '15

16 Aug '15

Hello, I am hoping someone here has had experience in setting up an iSCSI target using 'targetcli'. I followed the following guide: <http://www.certdepot.net/rhel7-configure-iscsi-target-initiator-persistentl…>. This is on my single host (with hosted engine currently running; I am using a seperate HDD for the iSCSI storage) The iSCSI initiator of my host, from it's information page in oVirt, is <iqn.1994-05.com.redhat:ba4cc8b3368e>, so I created an ACL with that name. Here is a result of the listing in the 'acls' directory for my IQN: --- START --- /iscsi/iqn.20...gt1/tpg1/acls> ls o- acls .............................................................. [ACLs: 1] o- iqn.1994-05.com.redhat:ba4cc8b3368e ...................... [Mapped LUNs: 1] | o- mapped_lun0 .................................... [lun0 block/block1 (rw)] --- END --- So it appears as though my host's initiator is mapped to my LUN 0. When I go in to oVirt and add iSCSI storage, the "Discover" finds my target, and I can even log in successfully, however when I click on the "LUNS->Targets" side tab, there are no LUNs listed, so I cannot add any iSCSI storage. Any ideas on why the LUN is not showing up? Thanks! :-) Regards, Alan

Multiple Networks on Self Hosted Engine
by Brent Miles 16 Aug '15

16 Aug '15

I am trying to install RHEVM 3.5 Self Hosted Engine. I have multiple vlan interfaces on the host that I would also like to have available on the self hosted engine. I have eth0.305 and eth3.306 on the host that I would like to have available on RHEVM. During the hosted-engine setup I get the option to add only one of interfaces but not both and do not seem to be able to add a second network at any point during setup or after the engine vm is installed. Any advise on doing this?

Hi, i've recently installed ovirt-engine-report, and i've a little problem with reports about VM. All graphs from "Network inteface usage" for VM are empty. Is it some configuration to do to get this data? All data for cpu/memory are ok. -- Lionel

Power Management for Nested VMs
by Amador Pahim 14 Aug '15

14 Aug '15

Hi, I'm used to have nested hypervisors for test/devel pourposes. The missing feature when using nested hypervisors is the Power Management device, keeping my env. useless to test HA, Cluster Policy with PM control and so on. This week I had contact with the Minyard's set of patches for qemu, currently in review, adding an ipmi device to qemu. Here a post with my first experiments: http://apahim.livejournal.com/2395.html Hope you guys enjoy. Feel free to comment or suggest improvements. Best, -- apahim

vdsm keeps removing BOOTPROTO=dhcp from ifcfg-ovirtmgmt
by Jakub Niedermertl 14 Aug '15

14 Aug '15

Hi all, I'd like my ovirtmgmt bridge to fetch ip address from dhcp, but vdsm keeps removing 'BOOTPROTO=dhcp' from /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt. I set the file as follows: DEVICE=ovirtmgmt TYPE=Bridge DELAY=0 STP=off ONBOOT=yes BOOTPROTO=dhcp MTU=1500 DEFROUTE=no NM_CONTROLLED=no IPV6INIT=no call 'sudo systemctl restart network' and ip address is successfully assigned. Then reboot the machine and ip address is not fetched and ifcfg-ovirtmgmt looks like this # Generated by VDSM version 4.17.0-1240.git487a19e.fc22 DEVICE=ovirtmgmt TYPE=Bridge DELAY=0 STP=off ONBOOT=yes MTU=1500 DEFROUTE=no NM_CONTROLLED=no IPV6INIT=no HOTPLUG=no Is there any way how to prevent vdsm from removing BOOTPROTO statement or make ovirtmgmt to work with dhcp? Environment: Host: runs in virt-manager vm, Fedora 22 vdsm: 4.17.0-1240.git487a19e.fc22 from http://resources.ovirt.org/pub/ovirt-3.6-pre/rpm/fc$releasever/ Thanks. Jakub

3.6 issues when using an existing gluster volume for the hosted-engine
by Michael DePaulo 13 Aug '15

13 Aug '15

Hi, I am attempting to setup a Ovirt 3.6 (currently beta 1) on a test environment with an existing (but empty) gluster volume for the hosted engine. I am currently experiencing 4 issues after I having deployed the hosted-engine appliance VM on only 1 oVirt host: 1. The gluster volume is not added as a storage domain by the end of the hosted-engine-setup. 2. When I try to import the gluster volume as a storage domain, I get this error: Error while executing action Attach Storage Domain: AcquireHostIdFailure In the logs below, I had not attempted to import it yet though. 3. The hosted engine VM is not listed, although the host is listed and its number of VMs is listed as "1". (I have seen recent emails/bug reports about what seems to be the same issue.) 4. The hosted VM shut down automatically after several minutes. I last ran ovirt-hosted-engine-setup on galactica on 2015-08-03 at around 22:47 -0400 #4 was probably caused by the fact that during a previous attempt (on 2015-08-02) to setup the hosted-engine, I had /var/lib/ovirt-hosted-engine-ha/ha.conf containing to local_maintenance=True. That value was not changed when I ran ovirt-hosted-engine-setup on 2015-08-03. Today, I ran the hosted-engine command to disable maintenance, and the hosted-engine VM started back up. I can access it over https, but the remaining issues are still present. ---- More Details: The 3 Gluster servers: Server 1: galactica: RHEL 7.1 with Gluster 3.7.3 Server 2: death-star: RHEL 7.1 with Gluster 3.7.3 Server 3: mothership: Fedora 22 with Gluster 3.7.3 I only intend for servers 1 and 2 to be oVirt hosts at this time. All servers have iptables disabled, are on the same LAN, have SELinux set to enforcing, and have gluster configured with the hyper-converged settings listed here: http://www.ovirt.org/Features/Self_Hosted_Engine_Hyper_Converged_Gluster_Su… I have DNS forward and reverse lookups configured correctly for all 3 machines plus the hosted engine. The existing gluster volume is "gv-virt", and it has the necessary "options" for gluster to work with oVirt. Other than the .trashcan folder, there were no files/folders on it when I ran ovirt-hosted-engine-setup. I am able to mount and write to gv-virt via mount.glusterfs. Note that I have run hosted-engine-setup repeatedly on servers 1 and 2 as I try to resolve these issues. My cleanup between running it may not have been correct, as exemplified by the local_maintenance setting. I have been deleting the files on the gluster volume between running it. I have the relevant contents of the relevant directories under /var/log/, /var/lib/, and /etc/ here: https://drive.google.com/folderview?id=0B2L_OrCln9ShMWprWVlpZVVocGs&usp=sha… I also put the `gluster volume status gv-virt` output there. Also, these 2 volumes are currently mounted on galactica: galactica.depaulo.org:/gv-virt 200G 2.7G 198G 2% /rhev/data-center/mnt/glusterSD/galactica.depaulo.org:_gv-virt /dev/loop1 2.0G 3.1M 1.9G 1% /rhev/data-center/mnt/_var_lib_ovirt-hosted-engine-setup_tmp2HOqSq Thanks in advance, -Mike
