[ovirt-users] Re: Ceph cluster on oVirt Guests
Hi, It appears it is. We tested it on the physical hardware with same CentOS 7 and same release of Ceph and it works like a charm. We also tried it with VMWare, and it works perfect. Of course, on VMWare we have to install open-VM-Tools in place of VMWare Guest tools. But with ovirt-guest-tools, we get error and open-vm-tools appears not designed for oVirt.

Post the completion of synchronization process, we modified the fstab and the VM went live. Now all well.

I am able to connect to conversion server. But none of the Hard Disks are listed to select for conversion. I opine, probably it is something to do with SCSI / RAID Card drivers.

Even after 4 full days, on the VM an Hour glass was shown and it kept reporting, hung task. Finally we had to run engine-update, that removed Zombie tasks and VM started showing as DOWN and we could remove the VM.

We have to manually intervene, stop the VMs, restart them on another server. Is there a way in which this migration can be automated? -- Thanks & Regards, Anantha Raghava Do not print this e-mail unless required.

Re: [ovirt-users] oVirt Nodes Monitoring
Hi, You can also monitor by enabling SNMP in Hosts. For this purpose, using the MIB, you need to build a Zabbix Template as detailed in the link here https://github.com/jensdepuydt/zabbix-ovirt We are monitoring Version Hosts with CentOS 7 and oVirt 4.0.x using this method. I will share the Zabbix-Template, we have built tomorrow as I, at the moment do not have access to my resources. -- Thanks & Regards, Anantha Raghava eXzaTech Consulting And Services Pvt. Ltd. Thanks Arsène Just for others benefit just adding the repository and installing the agent won't work. Need to add it to SELINUX.

[ovirt-users] Ubuntu VM does not complete reboot cycle without Console Open
Hi, I have been observing that Ubuntu Precise VM, if restarted using a crontab at a given time, stops at the OS / Kernel Selection screen and does not complete the reboot. If we issue the reboot command with Console open, the same command works without any issues and the VM boots properly. This issue happens only with Ubuntu Precise and not with Trusty or Xeniel or even with any of Rehat distributions or CentOS. Interestingly, it doesn't happen with VMWare ESXi. I also read somewhere that this issue is with VDSM 3.6 and it seems to continue with VDSM 4 as well.

Re: [ovirt-users] Exporting VM as ova
Hello Arik, Interesting.. I was thinking that, by converting to OVA appliance, we can release our product as appliance that will work on Xen, VMWare or KVM. Now OVA works both on Xen and VMWare and both can be interchanged with each other. Do you mean to say that both Xen and VMWare have written specific parsers to convert the disk formats amongst each other. Xen, I am talking about Citrix Xen. -- Thanks & Regards, Anantha Raghava eXzaTech Consulting And Services Pvt. Ltd. Do not print this e-mail unless required. Save Paper & trees.

For example, without converting OVA that was generated by VMware using virt-v2v oVirt cannot consume it since the VMDK disks format is not supported in oVirt. Another example is the OVF representation that differs among various virtualization management platforms. So if you are trying to migrate a VM from oVirt to another platform and assume you'll get this out-of-the-box by having an OVA that is generated by oVirt, I'm afraid you'll be disappointed in case the target platform doesn't support the format of the disks or doesn't know how to parse the OVF that is generated by oVirt.

If you specify a disk FIRST and then try to to change the virtual CPU configuration it will no longer work.

But we did not take a Volume Snapshot at the storage level :-( We will make an attempt & post the results. -- Thanks & Regards, Anantha Raghava eXza Technology Consulting & Services Do not print this e-mail unless required.

I guess that lv data was not affected, only the lvm metadata was destroyed. When an lv is active, you have access to certain segments on the pvs backing the lv. Deleting the lvm metadata should affect running vms. The data of the vms is probably still on storage and probably can be restored by using the lvm backup information. You should be able to create a device mapper device mapped to the same segments on storage as the original lvs and restore the data, but I never tried to do this. ++looping Yaniv Kaul -- Thanks & Regards, Anantha Raghava eXza Technology Consulting & Services Do not print this e-mail unless required.

Hello Yaniv, I sincerely apologize for pushing you guys. We have taken the steps suggested by you only to realize that the Storage volumes are having NTFS format instead of LVM2!! Hence become not accessible. We were able to create new LUNs and add them properly as storage domains. But only surprising part is all running VMs continued even after the storage domain and DC going down till such time, we manually shut them down.

Re: [ovirt-users] 100% disk utilization on Hosted Engine
Hello Didi, Apart form oVirt-engine, nothing else is running on the server. Engine is running on CentOS 7.2 minimal installation. We have 2 hosts, 1 iSCSI storage, about 19 VMs and 5 Networks. In this setup oVirt engine is running in a separate VM created on VMWare ESXi. In 20 odd days, it consumed around 70GB out of 100 GB!!! In another setup, we have only one host, hosted engine, 9 VMs, 2 Networks, 1 FC Storage. In about 30 odd days, 100% of available 100 GB consumed!! It is in this setup CentOS is not allowing us to loginto engine VM as no space to create any temp files on the storage. We have ISO Domain created on this engine VM. But that's only about 3 GB in size. Both setup are not exposed to internet. Hence, any malware is ruled out. We have observed, the logs are also growing and we have not found that logs are not rotating. All logs right from day one are kept intact. Nothing in the user files. Because no user is allowed to use this VM. What else it could be? 100% consumption without even a warning, is very strange. -- Thanks & Regards, Anantha Raghava eXza Technology Consulting & Services Do not print this e-mail unless required.

Re: [ovirt-users] oVirt Active Directory Integration
Hi, I am able to add the user to oVirt and assign role. Just to test, I assigned one user as "super user" and I am able to login to Administrator Portal. Need to read a bit more about roles and their predefined rights.

[ovirt-users] Peculiar Problem in migrating storage from one to another domain
Hi, I had created a Windows VM accidentally with storage in EXPORT_DOMAIN rather than using a specified MASTER_STORAGE Domain built on iSCSI storage. Realising the mistake, I moved the VM's disk from EXPORT_DOMAIN to MASTER_STORAGE domain. The engine reported that disk moved successfully. When I attempted to start the VM, I am getting error "Cannot start VM, related operation is in progress". This error has persisted over last 24 Hours!!. I attempted to remove the disk from VM, same error appears. When I try to delete disk from MASTER_STORAGE Domain, same error appears. What could have gone wrong in this disk movement? I am using oVirt 4.0.2 on CentOS 7 and 2 hosts in the cluster are also with CentOS 7 base OS on which the Hypervisor is installed. -- Thanks & Regards, Anantha Raghava eXza Technology Consulting & Services Do not print this e-mail unless required.

Re: [ovirt-users] Adding iSCSI Storage
Hello Elad, Thanks for quick reply. That was really quick. Your assessment was right. On the iSCSI storage multiple iSCSI initiators were disabled. Hence the authorisation error. Once I enabled the multiple iSCSI initiator support, the primary storage domain came live and DC also went live. However, I am still confused on iSCSI mutipathing and bonding. Will try creating bonds and write back if I get stuck. -- Thanks & Regards, Anantha Raghava eXza Technology Consulting & Services On Thursday 25 August 2016 01:02 PM, Elad Ben Aharon wrote: Thanks. vdsm.log had been rotated since, it's too new and doesn't have the relevant information. From engine.log [1] it seems that you had an iSCSI authorization failure during login to targets for first storage domain creation in pool. It happened during storage pool creation. It does seem you've hit https://bugzilla.redhat.com/show_bug.cgi?id=1359788 <https://bugzilla.redhat.com/show_bug.cgi?id=1359788> since you report this domain is stuck in LOCKED state.

For first storage domain creation in the new DC, in case it's iSCSI, please make sure you provide the correct iSCSI credentials for login or use other type of storage (NFS for example).

[ovirt-users] Hosted Engine & FC Data Domain
Hello, I had recently installed oVirt 4.0.1 Hosted Engine with FC (SAN) Storage. I could install the oVirt, deploy hosted-engine. But when I accessed the Engine Web Admin, I noticed the following: a. There was no Data Domain. I had to import the FC LUN, on which the Hosted Engine's Disk resided into Storage manually. But when I attempted to attach the data domain to Data Center, it failed. b. I ended up removing all configuration, and recreated the FC LUNs. This time, I created two LUNs, on one LUN, the Hosted Engine resided. This time, first, I had to import the second LUN as master Data Domain and add the LUN on which Engine VM resided as just another Data Domain. Now the questions: i. Will Hosted Engine not automatically import the hosted_storage as master data domain? Why does it throw error when attempted to import and attach to DC? ii. Is it necessary to have another data domain as master data domain, before attaching hosted_storage? iii. How do we change the master data domain from one to another? -- Thanks & Regards, Anantha Raghava ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Exactly. And if you do not pass --change-db-credentials, you'll simply get the default, which is to just give permissions to the user creating the schema. Bottom line: If you used only defaults, and did not create users and give them grants, there is no difference between the options. They'll create the exact same database. If you did add grants, you must choose. I agree it's not very user-friendly to require choice, but please take into consideration that if you had a large setup (say hundreds of VMs or more) with dwh history included over some time, you'll have a large database, and I think it will be much less friendly if we "just try" restoring (which can take several hours then) and fail in the end due to missing users.

[ovirt-users] Terribly slow web consile post migration of oVirt Engine from one host to another host
Hi, I was able to migrate the oVirt Engine from one host to another using engine-backup utility. On the new host, the data is loaded properly but the Administration Portal is terribly slow. It take about 2 to 3 minutes to allow me to enter user name & password. Once logged in, it takes hell a lot of time to show up the data. Click on a tab, we need to wait for a good amount of time to see the actual data. Even the refresh is taking time to execute although it is set to 5 Seconds. But if I enable old server and connect, every thing works quickly. Note: 1. We do not have DNS in our environment. 2. Engine name & even the IP is retained the same. 3. Before migration, we stopped ovirt-engine on old server, took the backup, shutdown & disconnected the old server. 4. We installed the ovirt-engine on new server, run engine setup, noted down the DB password, did engine-cleanup, restored the data using engine-backup utility and executed engine-setup again. It did recognize restored data and only httpd configuration was sought and we selected the defaults. Result is terribly slow Web Console. First, we attempted to setup ovirt-reports and later removed it thinking that may be slowing down the engine server. Yet the same result. Commands used to backup from old server: "engine-backup --mode=backup --file= --log= --provision-db" Command used to restore on new server: "engine-backup --mode=restore --file= --log= --change-db-credentials --db-host=localhost --db-user=engine --db-name=engine --db-password= --no-restore-permissions" The command executed without any errors, resulting in a terribly slow web console. Note: Without --restore-permissions, the restore fails. Did not understand what to give as restore permissions. Hence used --no-restore-permissions. *Hardware configuration:* * **Old Server:* i3 Processor, 4 GB Memory, 1 Gbps NIC *New Server :* Lenovo x3250 M5 Server with Intel Xeon Processor, 16 GB RAM, 2 X 1 Gbps NIC.

You can increase the maximum downtime in VM properties dialog (500ms by default, you can go up to whatever is feasible for your VM, seconds, tens of seconds) Bandwidth is limited to work on 1Gb network, if you have 10Gb availabl you can also tune /etc/vdsm.conf on each host and increase the maximum bandwidth 10 times Thanks, michal -- Thanks & Regards, Anantha Raghava On 03 Jun 2016, at 07:14, Anantha Raghava wrote: Hi, We have just installed oVirt 3.6 on 3 hosts with storage volumes on Fibre Channel storage box.

Re: [ovirt-users] oVirt Windows Guest Tools & Live Migration issues.
Hello Michal, Thanks for quick feed back. Windows Guests Agents - Where do I download them from? Not getting the proper links. Or is to a part of virt-drivers that we use during installation. Live migration failure - These are pretty busy VMs if not big. The event does not show any specific message but just as migration failed. Is the reason logged somewhere? Please share the log location so that I can check & share the log for meaningful message and proper screen shots. -- Thanks & Regards, Anantha Raghava On 03 Jun 2016, at 07:14, Anantha Raghava <mailto:rag...@exzatechconsulting.com>> wrote: Hi, We have just installed oVirt 3.6 on 3 hosts with storage volumes on Fibre Channel storage box.

[ovirt-users] Fwd: Struggling to get the network work
Hi, Just to add on the previous mail, the vNIC is added over a Physical NIC that does not have any IP address, but enabled and connected. -- Thanks & Regards, Anantha Raghava Forwarded Message Subject:Struggling to get the network work Date: Wed, 25 May 2016 15:41:06 +0530 From: Anantha Raghava Reply-To: rag...@exzatechconsulting.com Organization: eXza Technology Consulting & Services To: users Hi, I have a peculiar problem with oVirt 3.6. Any VM connected to ovrtmgmt is working absolutely fine, bu the VMs (Windows Guests) in different VLANs say 10, 32, 34, 40, 48 & 69 are not able to even ping their respective gateways. In other words, network packets are not coming out of the VMs at all. 1. Our infrastructure consists of Lenovo Flex Chassis with 3 Lenovo x240 Compute nodes. All nodes are up and running and VMs are also created and guest OS installed. 2. Chassis switch has a trunk port that carries all VLAN traffic. 3. I have created logical networks and added VLAN tags (10, 32, 24, 40, 48 & 69). 4. I have attached the vNIC to each host and assigned static IP in respective VLANs. For example in VLAN 32, the vNIC is assigned with 172.20.101.70, subnet: 255.255.255.192, Gateway: 172.20.101.65 5. VMs are mapped with respective vNIC and assigned IPs in respective VLAN. For Example, VM in VLAN 32 has 172.20.101.79 as IP, 255.255.255.192 as subnet and 172.20.101.65 as gateway. Now, VM is able to ping vNIC in VLAN 32, but neither VM is able to ping the gateway nor hosts are able to ping vNIC or the VM. We even attempted with replacing a trunk port with access port, but same issue continues. What could have gone wrong? Any thing missing on oVirt configuration? A quick help is highly appreciated. -- -- Thanks & Regards, Anantha Raghava ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
