Re: [Users] Ovirt Engine as a VM

This should be possible, when the cluster is powered up for the first time it would require some specialized instructions to fire up the ovirt engine on a node. Does the guest(VM) hosting the ovirt-engine be managed by the ovirt-engine? If It does, it looks like a logical loop here. Say, if the ovirt-engine stop the hosting VM, the ovirt-engine will also be stopped. P.S. Are there any plans for redundant ovirt engines in the works?

I have been looking at the different possible network configurations shown at http://www.ovirt.org/wiki/Vdsm_Network and trying to work out how to achieve the second topology ( bridge over vlan over nic ). I can see that it is possible to assign a logical network to a physical network on a node but how can you add more than one as this is a dropdown menu? My nodes have two NICs, one of these is for the management network but I could like to have a number of logical networks (with different VLAN tags) connected to the other NIC. Is this currently possible using the web UI? Very simple 1. create your logical networks with vlan tags in the data centre 2. assign those networks to the relevant cluster Now, assuming we are going to assign network X with tag 100 and network Y with tag 200 to eth0 on a host: Edit eth0 on the host - assign network X to it see how eth0.100 gets created and the X network attached ot that tagged interface Edit eth0 again, assign network Y see how eth0.200 gets created and Y is attached repead for additional tagged networks Yes, we can do these manually if we are the master of the system administrator. But I think we should provide a UI to the user and VDSM management API in the backend. Also, it is a quite a challenge to assign the VMs in different host to the same vlan. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users -- Shu Mingshum...@linux.vnet.ibm.com IBM China Systems and Technology Laboratory ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[Users] permission settings on the specified path do not allow access to the storage
Hi,
My ovirt-engine was setup on a vm host with ip:xxx.xxx.xxx.112. And
I am trying to create a new domain with ovirt-engine UI by the
Storage-- New Domain. And the following error happened. However I
can mount the xxx.xxx.xxx.110:/data by mount -t nfs
xxx.xxx.xxx.110:/data /mnt manually in the ovirt-engine host, also a
new file can be created under the mounted directory with touch xx. It
looks to me that there is no permission problem when I access the remote
nfs path manually. So does ovirt-engine enforce additional permission
check beside the normal unix file permission check here?

Is it a master data domain? Does you mean you can not remove the data domain from oVirt engine? It seems that you removed all the meta data there, that will make oVirt engine broken.

Then I tried to start the VDSM daemon, however it did nothing. After checking the vdsm.log file, the latest message was five hours ago and useless. Also, there was no useful message in libvirtd.log. - please ping between host and engine It works in both ways. - please make sure there is no firewall on blocking tcp 54321 (on both host and engine) No firewall. also, please provide vdsm.log (from the time network issues begun) and spm-lock.log (both located on /var/log/vdsm/). as for a mitigation, we can always manipulate db and set it correctly, but first, lets try the above. Also, there is no useful message in spm-lock.log.

Re: [Users] Online snapshot
After looking into a qemu a bit, I believe the snapshot operation on the disk in oVirt is not a live snapshot, because the guest VM will be paused by qemu when the snapshot is undergoing.That is what qemu monitor command snapshot_blkdev does and VDSM depends on that command in low level.Most likely, the pausing time is non-trival for a normal snapshot.

Possibly something as crude as provisioning new VMs with oVirt then replacing the virtual hard drives? this would work - just create the VM on an NFS storage domain with a disk the same size as origin, and copy over the disk you had. a bit trickier for iscsi, so i'd do this with nfs. Thanks - Trey Why is it trickier with iSCSI? Currently the only Data Center I have functioning in oVirt only has iSCSI storage available. with iscsi, you will have to create the disks as pre-allocated, and use DD to overwrite them. NFS doesn't have to be pre-allocated. and since you are using pre-allocated, you need to use the RAW format iirc Currently most of my KVM VMs are qcow2, so converting them to raw would not be a problem. However, why is DD necessary? Why can't I overwrite the image_name.img with my *.img file ? Since I've used mostly qcow2 in my time with KVM/libvirt I may lack some understanding of how to correctly handle raw images. in both cases there aren't any .img files. you can convert you qcow2 to raw before copying them over to iscsi or nfs using qemu-img convert. it is not necessary, but will save you failing on small details between the two. using the export domain is safest, even though it doubles the amount of IO Would a qcow2 image with preallocation=metadata be possible on an iSCSI data store? ayal? nope. metadata preallocation means that each logical block has a corresponding physical block. Ayal, by saying logical block and physical block here, what do they stand for in linux systems? I guess, physical block is the scsi lun disk, logical block is lvm disk? right? With files this is fine as you can seek wherever you want and the file will remain sparse. With block devices this makes little sense as the second the guest accesses a block which is mapped to an unallocated physical block we'd have to allocate all the area up to that point.

Re: [Users] Hot Snapshotting of virtual disks
Basically, backup is different from snapshotting. Backup should have another storage different from the current share storage to store the disk content. oVirt 3.1 does have support for live snapshot of the VM disks and Qemu 1.1 is required at least to support this operation. In oVirt 3.1, you can also create an backup domain to store the VM disks, but I think it is not the real backup to another physical storage. So you may have to copy the snapshot made to other physical storage manually . 2012-10-18 9:20, Jason Lawer: Hi, Can anyone give advice on what they are using for backup on their ovirt deployments. We have been using tar balls rsync on our linux servers, but are looking for something more manageable and the number of servers grows rapidly. I ask because I have been looking at a few options. The first idea that came to mind was a hot snapshot of the virtual disk, however from what I can see ovirt won't allow that.

But i'm able to start more VMs and hava a higher usag of my swap partiotion so i think the change had the desired effect Oh, does this take advantage of host swap space as well? I thought I had read oVirt could do that somewhere, but I have been reading about so many different virtualization systems over the last few months that when the RHEV 3.1 Admin Guide https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Virtualization/3.1-Beta/html-single/Administration_Guide/index.html did not mention swap space in section 4.2.2.2. Memory Optimization Settings Explained, I was not sure if it applied here. This is all it says at the moment: Memory page sharing allows virtual machines to use up to 200% of their allocated memory by utilizing unused memory in other virtual machines. This process is based on the assumption that the virtual machines in your Red Hat Enterprise Virtualization environment will not all be running at full capacity at the same time, allowing unused memory to be temporarily allocated to a particular virtual machine. Do you have a reference handy that confirms and explains this? I put some speedy SSDs in my hosts to hopefully take advantage of this (and maybe run gluster), so I am hoping to see that in print somewhere. I'll dig it up if you don't have it handy, but a confirmation that this is your experience and understanding would make me feel better in the mean time. let me explain my (now fixed) problem i have a ovirt host with 8 GB Ram and 12 VMs every with 256 MB Physical Memory Guarantee. When i start my two mysql-cluster vms they will use the 256 PMG plus 3,75 GB MS they have defined a max of 4 GB MS. At this poitn now the problem begins the mysql taken the hole memory in both vms and now there is no more free ram at the host and it is not possible to start more vms. In my understanding, you need to hard cap the physical memory used by the cluster VM. That will make sure all of the physical memory used by the VM will not exceed the cap, say 2G. In total, the two cluster VMs will use 4G memory at most, then the host will have 4G memory at least to start other VMs. Is that what you want? (this is also speculation im not a expert) So i need for my understanding a higher rate of memory overcommit to be able to start all vms, and for that the host must use the swap to have enough memory for overcomit to start all vms and yes the higher the rate, the worse the performance.

David Wilson: Hi everyone, Some feedbackon this error, and a question I hope that someone could possibly assist with. I managed to get the guest running again byusing dd and qemu-img to export the filesystem image and base image, convert to raw format and run a fsck on the looped partition. I am happy you make that work. Can you describe more details about how you dd the guest image? And how did you use qemu-img to export the filesystem image and base image. When mounted as a loop filesystem, fsck easily repaired it. Any ideas why oVirt kept pausing the guest and did not allow fsck to repair the filesystem?

Re: [Users] What do you want to see in oVirt next?
1) I would like to have the ability to import an existing VM image from outside as a template into oVirt, then new VMs can be cloned from this template. 2) I would like to have an oVirt trial package based on nested-kvm. This package will contain several vdsm node images, one engine image and one storage several image. After the package is installed into a physical server, the images can be started as VMs including the engine, the VDSM nodes, the storage server. The VDSM nodes must support nested-kvm to have nested VM on them. It is very quick and simple for a new-comer to try the oVirt envionment.

Hi,
So, Finally I reinstalled the whole cluster after I have exported
every VM.
I followed this wiki
http://wiki.dreyou.org/dokuwiki/doku.php?id=ovirt_rpm_start31.
Everything went up except that I just have one host installed in the
cluster. The other host is still serving the old cluster
When trying to import my old VMs I got problems with some of
them not
beeing imported. But 3 of my VMs did and one of them was my
mailserver... but when I try to start the VM I hit the wall again.
I have attached the vdsm.log, right now I cant see the forest
for all
the trees

Re: [Users] Storage domain mount options
Alexandru Vladulescu: Hello Guys, I would like to ask you help for the following problem I am facing right now. As we know, on the Storage tab we can configure storage domains in many types. I am using NFS, and when configuring a such export on the Advanced Parameters section we can only adjust the NFS version, Retrans and Timeout. After a successful configuration setup, on all hypervisors I have the mount share declared attached. The result of mount for the share datastore looks like below: nas01.net:/datastore01/nas01.ISO on /rhev/data-center/mnt/nas01.net:_datastore01_nas01.ISO type nfs (rw,soft,nosharecache,timeo=10,retrans=6,vers=4,addr=10.20.30.10,clientaddr=10.20.30.102) All good and sound but how can I tune the NFS mounting command, for example let's say adding noatime value to the mount option list ?

Re: [Users] Storage domain mount options
Alexandru Vladulescu : Dear Shu, Exactly what I was saying, in that section we can only change in the Advanced Parameters the NFS version, the Retransmissions and the Timeout. Sorry, was not seeing these. I am afraid you can not append other options, for neither ovirt engine nor VDSM accepts other options than Retransmissions and the Timeout. Therefore I see exactly no field for additional mount options. As I know there is a thread on the mailing list about the new features that should be included in the 3.2 version release. I think would be useful to include this one too to the GUI, but again my question, how could this be modified in the stable 3.1 release ?

Re: [Users] Configure NFS resource from Host
jj197005: Hello everybody, I'm trying to configure and install oVirt for test in our University faculty. I have installed an engine an a host, both of them with Fedora 17. The engine is working and I can log-in in the Data Center with admin user. I have tried to add my host to the data center portal and I successfully done. After that I have tried to add a NFS resource which is in the host that I have added. If I open a console in the engine and log-in as vdsm user, I can mount the NFS resource without problems. The problem is when I tried to add this NFS resource to the Data Center. Have you tryied to open an console in the host and tried the same command in the host as in the engine? I have followed the tutorial http://www.ovirt.org/Quick_Start_Guide#Configure_Storage, but when I have completed the form and pressed Ok, after one or two minutes I receive one screen with bellow error: Error: A Request to the Server failed with the following Status Code: 500 I'm attaching the vdsm.log file with the lines that are created with this operation.

Re: [Users] Installing a lab setup from scratch using F18
2013-1-22 2:11, Joop: As promised on IRC (jvandewege) I'll post my findings of setting up an ovirt lab environment from scratch using F18. First some background: - 2 hosts for testing storage cluster with replicated gluster data and iso domains (HP ML110 G5) gluster data or cluster data? - 2 hosts for VMs (HP DL360 G5?) - 1 managment server (HP ML110 G5) All physical servers have atleast 1Gb connection and they also have 2 10Gb ethernet ports connected to two Arista switches. Complete setup (except for the managment srv) is redundant. Using F18-x64 DVD and using minimal server with extra tools, after install the ovirt.repo and the beta gluster repo is activated. This serves as a proof of concept for a bigger setup. Problems sofar: - looks like F18 uses a different path to access video since using the defaults leads to garbled video, need to use nomodeset as a kernel option Do you mean the VDSM host installed with F18 or the guest in the host with FC 18 here? I suppose you don't have much chance to access the graphics screen of the VDSM host. - upgrading the minimal install (yum upgrade) gives me kernel-3.7.2-204 and the boot process halts with soft locks on different cpus, reverting to 3.6.10-4.fc18.x86_64 fixes that. Managment is using 3.7.2 kernel without problems BUT it doesn't use libvirt/qemu-kvm/vdsm, my guess its related. - need to disable NetworkManager and enable network (and ifcfg-xxx) to get network going - adding the storage hosts from de webui works but after reboot vdsm is not starting, reason seems to be that network isn't initialised until after all interfaces are done with their dhcp requests. There are 4 interfaces which use dhcp, setting those to bootprotocol=none seems the help. Usually, I use the static IP for each server because the engine add the VDSM host by IPs. - during deploy their is a warning about 'cannot set tuned profile', seems harmless but hadn't seen that one until now. - the deployment script discovers during deployment that the ID of the second storage server is identical to the first one and abort the deployment (Blame HP!) shouldn't it generate a unique one using uuidgen?? Things that are OK sofar: - ovirt-engine setup (no problems with postgresql) - creating/activating gluster volumes (no more deadlocks) Adding virt hosts has to wait til tomorrow, got problems getting the dvd iso onto an usb stick, will probably burn a DVD to keep going.

Re: [Users] VM migrations failing
Hi,
Just curiously, did you install oVirt packages from
http://resources.ovirt.org/releases/nightly/rpm/EL/6/noarch/ ?
And there is no stable oVirt release 3.1/3.2 for RHEL.
Dead Horse:
The nodes are EL6.3 based.
Currently installed libvirt packages:
libvirt-lock-sanlock-0.9.10-21.el6_3.8.x86_64
libvirt-cim-0.6.1-3.el6.x86_64
libvirt-0.9.10-21.el6_3.8.x86_64
libvirt-python-0.9.10-21.el6_3.8.x86_64
libvirt-client-0.9.10-21.el6_3.8.x86_64
and qemu packages:
qemu-kvm-0.12.1.2-2.295.el6_3.10.x86_64
qemu-kvm-tools-0.12.1.2-2.295.el6_3.10.x86_64
qemu-img-0.12.1.2-2.295.el6_3.10.x86_64
Thus my presumption here given the above is that
virDomainMigrateToURI2 has not yet been patched and/or back-ported
into the EL6.x libvirt/qemu?
virDomainMigrateToURI2() is supported in libvirt-0.9.10, I am not sure
if qemu-kvm-0.12.1.2 supports it.
/var/log/libvirtd.log may help to verify this assumption

Solution here was to connect to each VM, shut it down and restart vdsmd and power it up again. There's no problem with the storage size as it has aprox 800GB free of space and running through NFS. All nfs mount points were running okay at that time. After the VM has been snapshoot-ed went into pause mode and had to un-pause it from GUI, but the VM was still responsive through network and operations. Has anybody seen something related to this by now or it's just related to 3.1 version ? Mentioning the fact that I did a research on the similar mailing list topics and could not find something related to this error. I would happily provide logs if needed.

Re: [Users] Export domain

Re: [Users] Export domain
So you have a block device in NFS server to be extended from 200 to 50GB?I think you should extend both the block device and the file system on the block device in the server side. To oVirt, it doesn't save the size in storage domain' meta-data and I believe the size is only stored in the engine server. The only issue is before the engine refresh its metadata in the next time, there is a window with the meta-data out of sync. Please let us know if it is successful.

Re: [Users] High Availability
Tim Hildred: If one host is down because of network interrupt or power failure, the engine should know how many HA VMs are down and find out the VM images on the storage domain to start the VM instances on another host in the cluster. Why do we need power manager to be configured? Power management allows the Manager to start highly available virtual machines on new hosts without worrying that virtual machine hard disk images will be corrupted. Imagine a situation in which the Manager cannot communicate with the host a highly available virtual machine is running on. If the host is still running as expected, and the virtual machine is also still running, the virtual machine is writing to its hard disk image. Tim, Thanks for clarification. That is what I expected. If the Manager starts that virtual machine on another host in the cluster, then both virtual machine instances will try and write to the disk image, and cause hard disk corruption. Power management lets the Manager be sure that only one instance of the highly available virtual machine is running, because the instance on the host the Manager couldn't communicate cannot survive a host reboot.

Is it required to force powering down the failing host forever to make sure the failing host will not come back to live again? * Power management must be configured for the hosts running the highly available virtual machines. * The host running the highly available virtual machine must be part of a cluster which has other available hosts. * The destination host must be running. * The source and destination host must have access to the data domain on which the virtual machine resides. * The source and destination host must have access to the same virtual networks and VLANs. * There must be enough CPUs on the destination host that are not in use to support the virtual machine's requirements. * There must be enough RAM on the destination host that is not in use to support the virtual machine's requirements.

Re: [Users] way to edit iSCSI storage domain?
Yuriy Demchenko: Hi, is there any way to edit iSCSI storage domain: change/add targets ? (lun, id, sn and actual content wouldn't be affected) Without VM export/import process - downtime should be as little as possible. I'm researching possibility to use oVirt in env where I have only FC storage, connected to 2 servers (and sadly, second server will be available later, hence my question about changing targets in oVirt) and bunch of blades, on which i would like to run virtualization (no fc storage connectivity) - so idea is to share storage via iSCSI/tgtd and use multipathd with failover mode to protect from storage I am not sure if the multipathd can recognize the FC path to the storage when the second server is available and regards it as the same as the iSCSI path used before. If it is not, I think the device under /dev/mapper may change when you cut the iSCSI path off and then enable FC path. That will definitely corrupt the meta data of the volume group which the storage domain is sitting on and the storage domain will be corrupted finally. corruption. -- --- 舒明 Shu Ming Open Virtualization Engineerning; CSTL, IBM Corp.

Re: [Users] way to edit iSCSI storage domain?
Yuriy Demchenko: I guess you misunderstood me I'm going to try this scheme: |STORAGE| FC / \ |SERV1/tgtd||SERV2/tgtd| iSCSI \ / |ethernet switches| iSCSI |blades|blades|blades| I am still confused if SERV1/SERV2 are used as a iSCSI bridge to the storage only or used as VDSM host also? If they are used as VDSM host and both of them can have FC channel to the storage, why not create FC storage domain for them instead of iSCSI domain? serv1/serv2 - connectivity isnt a problem, multipathed FC scheme, all good. Same lun accessible for both servers and than exported via tgtd to iSCSI: with different target names (iqn.2013-03.serv1:store, iqn.2013-03.serv2:store), but same vendor_id, product_id, scsi_sn, scsi_id. That way client can login into both targets and see lun as multipathed device. And multipath failover scheme (via custom config with path_grouping_policy=failover for corresponding vendor_id/product_id) is on blades-clients - so they use only one target at time (no round-robin or similar stuff), but with ability to switch to another target in case one of serv1/serv2 is down. However, in my case serv2 would not be available during oVirt setup (need to setup ovirt and virtual servers to move stuff first), so i cant enter both targets on storage domain initialization - that's why I'm asking if there's any way to edit storage domain details after initialization without destroying it (maybe directly via sql or something).

I still dont understand the whole of the ovirt storage mechanism. More information was in the node vdsm.log - It pointed here. /dev/mapper/9ed5a2fe--ae4c--433f--a15f--2c710ed5156f-master One fsck later problem resolved.

Re: [Users] VDI using oVirt
oVirt project was initiated from virtual desktop project. It supported an open desktop protocol SPICE from the beginning which gave a nice 2D performance driven by the various graphics drivers on different OSs. Do you have a target in mind? Like what is ratio of virtual desktops per physical servers? Does the virtual desktop support support video playback? Do you need to support other client protocol besides SPICE? 2013-4-10 5:34, John Baldwin: Any good guides on setting up VDI using oVirt???

Re: [Users] virt-v2v
You can get the mount path from the admin portal. system---storage---select a storage domain---In the general tab page, you can have the nfs export path. supo...@logicworks.pt: well, I run the virt-v2v from the engine server, if I do a showmount -e it will show me the iso domain. The NFS/export storage is located at a NAS on the LAN, so I think I need the path to that NAS, how can I found it? *De: *Jonathan Horne jho...@skopos.us *Para: *supo...@logicworks.pt, Users@ovirt.org *Enviadas: *Quarta-feira, 17 Abril, 2013 20:33:29 *Assunto: *RE: virt-v2v I imagine “showmount -e” will show you the NFS path.

Re: [Users] Lun snapshots by a san
pierre Labanowski: Hello everybody, I have a question, or more precisely information or best practice. I use oVirt 3.1 with an attachment on fiber channel on my SAN. Makes it even the San snapshots that are replicated on a remote site. it's a procedure for adding a new Storage Domain to another Data Centers (oVirt) in order to recover the state of a VM snapshoted by the SAN? If I understand correctly, the remote SAN of you can snapshot the storage domain(physical lun in the SAN) lively. And you hope to recover the storage domain with the previous snapshot stored in the SAN. So you create a new storage domain for another data center and restart the VM from the newstorage domain. I am not sure if the VM disks in the storage domain snapshot is in consistent date if the SAN snapshot the VM in a running state. I think the VM OS should be notified and make sure it is in consistent state before the SAN can do the snapshot, also the VM OS should be notified with the finish of the snapshotting.. I've read the documentation on Disaster Recovery but it's for the site-to-site failover (i don't have dual architecture of ovirt) while my demand here is for the state recovered a current domain. And only to export the VM(snapshoted by a san) for restore in the current storage (production). thank you Pierre ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users -- --- 舒明 Shu Ming Open Virtualization Engineerning; CSTL, IBM Corp.
