A few questions arose and I didn't succeed finding the answers on the web. I somehow don't get how the iSCSI integration in ovirt works. - As far as I understand from the information I found, all iSCSI access for the virtual machines is done through one host. Does this mean, that all disk related traffic of the other host is going to the first host and then to the iSCSI storage? - no, every host has a separate access to the storage, only the storage setup is done by a single host and then it's available for everyone. In this case. How are the virtual disk images then made available for the VMs on the other host? - If the first host fails, the engine will get started on the other host. Will the engine deal with the fact, that now the iSCSI storage domain has to be accessed using the other host. Or is iSCSI just not suitable for this kind of usage. - Has the self hosted engine to use a different iSCSI lun than the storage domain?

Re: [ovirt-users] Functionalities of GlusterFS (vs VMFS)
Hello, Well, I did not have success with my questions ;-) May be you have considered they were too far from oVirt... For the first one, after further research, I've found that it is OK (GlusterFS over FC [SAN mode])... But, about performance, I can't find useful results... Do you have links about GlusterFS vs other FS (VMFS, GPFS, etc...) ? Thank you. David.

Re: [ovirt-users] VM Deployment By Template
Punit, What file system is your VM's partition, what operating system and version ? A question to others, if the doco says we support disk resize since 3.4, for what virtual disk type, and which operating systems and their partition types are supported by this. I would have believed you would needed to have used LVM and then add the new disk space as a new LUN, and map the new lun, while also using a file system that allows for expansion. Some file systems like XFS can be extended (i.e. grow) while being mounted. This is about the limit of my knowledge so if you know more, please let us know what is possible. 3. we support disk resize since 3.4 (iirc), which you can do post VM provisioning. http://www.gnu.org/software/parted/manual/html_node/parted_31.html Grow partition 1, into the adjacent free space: (parted) resize 1 0.063 874.9http://geekpeek.net/resize-filesystem-fdisk-resize2fs/ http://www.linuxuser.co.uk/features/resize-your-disks-on-the-fly-with-lvm http://docs.oracle.com/cd/E37670_01/E37355/html/ol_grow_xfs.html You can use the xfs_growfs command to increase the size of a mounted XFS file system if there is space on the underlying devices to accommodate the change. http://www.ovirt.org/Features/Online_Virtual_Drive_Resize Features/Online Virtual Drive Resize QEMU-GA * support for notifying the guest and updating the size of the visible disk: [Yet?] To be integrated http://serverfault.com/questions/122042/kvm-online-disk-resize AFAIK, this is not possible -- you can add new disk images, and as you point out you could also add new images to an LVM volume, but in order to resize an active, bootable disk image you need to be able to shut it down and edit the partitions. It is possible to move a Linux system between disks while it's running. The limitation is that you cannot alter partitions on a disk that has partitions in use. To do this your root filesystem must be on an LVM, this often means that you have to have a separate boot filesystem (this is not, however, essential, it just makes things easier) At Thursday, 28-08-2014 on 16:49 Shahar Havivi wrote: On 28.08.14 11:05, Punit Dambiwal wrote: Hi All, Please help me to solve this problem...or suggest me any workaround ??

It is possible to move a Linux system between disks while it's running. The limitation is that you cannot alter *partitions* on a disk that has *partitions* in use.

Hi all
When we try to migrate a VM on oVirt “Engine Version: 3.4.3-1.el6 ” form host
A to host B we’ll get this Errormessage: “Migration failed due to Error:
Fatal error during migration”.
It looks like, this occurs only when thin provisioned HDD’s attached to the
VM. VM’s with preallocated HDD’s attached, migrate without a problem.
Hope someone can help us to solve this issue.
it looks more like a network error:

[ovirt-users] oVirt/gluster storage questions for 2-3 node datacenter
Hi, I am currently testing oVirt 3.4.3 + gluster 3.5.2 for use in my relatively small home office environment on a single host. I have 2 Intel hosts with SSD and magnetic disk and one AMD host with only magnetic disk. I have been trying to figure out the best way to configure my environment given my previous attempt with oVirt 3.3 encountered storage issues. I will be hosting two types of VMs - VMs that can be tied to a particular system (such as 3 node FreeIPA domain or some test VMs), and VMs which could migrate between systems for improved uptime. The processor issue seems straightforward. Have a single datacenter with two clusters - one for the Intel systems and one for the AMD systems. Put VMs which need to live migrate on the Intel cluster. If necessary VMs can be manually switched between the Intel and AMD cluster with a downtime. The Gluster side of the storage seems less clear. The bulk of the gluster with oVirt issues I experienced and have seen on the list seem to be two node setups with 2 bricks in the Gluster volume. So here are my questions: 1) Should I avoid 2 brick Gluster volumes? 2) What is the risk in having the SSD volumes with only 2 bricks given that there would be 3 gluster servers? How should I configure them? 3) Is there a way to use local storage for a host locked VM other than creating a gluster volume with one brick? 4) Should I avoid using the hosted engine configuration? I do have an external VMware ESXi system to host the engine for now but would like to phase it out eventually. 5) If I do the hosted engine should I make the underlying gluster volume 3 brick replicated? Thanks in advance for any help you can provide. -David ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Thanks for the reply! So when keeping a snapshot for a long time I have to keep an eye on how large it will get over time. The snapshot's size itself is determined when it's taken according to the disks size at the time. It then stays the same. When taking a snapshot, the active image of the disk is frozen at this point in time, and a new, empty active image is created to hold the new data on the disk. The new data is saved in the form of diffs, so if there are mainly additions to the snapshot time, the space difference of the snapshot is negligible. But if the diffs include many reductions from the snapshot's state - this might consume a lot of space, again, depending on your usage. Note that you're also limited by the disk's size. But there's no (or very little) performance impact or potential issues from keeping snapshots (other than the storage pool filling up maybe)? All the vm operations take into consideration snapshots. Storage is an issue, but so is every operation you'll make on the vm. When you have one image, the vm is handled only through this image. But when you have several, for each operation the right layer will search for the existence/ability to do the operation in all the snapshots (worst case). So there is in fact an impact, but it's due to the mere existence of the snapshots and their number, not their age. We support 26 snapshots per VM, but you should only use it if you actually need the backup. If you need RT performance, try to avoid it as possible.

Ryan, Disk snapshots consume fixed storage space (fixed since time of creation). The more differences there are from on your disk since the snapshot was taken, the more space is consumed, but that happens with no relation to the snapshot. If your frequent changes are in the form of adding data to you disks (on top of data snapshot time), then the space consumption of the snapshot is negligible. If you are undoing stuff from the snapshot time, there is actually more space consumed (to save the differences), otherwise the space would have just been released.

Thanks for the reply! So when keeping a snapshot for a long time I have to keep an eye on how large it will get over time. The snapshot's size itself is determined when it's taken according to the disks size at the time. It then stays the same. When taking a snapshot, the active image of the disk is frozen at this point in time, and a new, empty active image is created to hold the new data on the disk. The new data is saved in the form of diffs, so if there are mainly additions to the snapshot time, the space difference of the snapshot is negligible. But if the diffs include many reductions from the snapshot's state - this might consume a lot of space, again, depending on your usage. Note that you're also limited by the disk's size. But there's no (or very little) performance impact or potential issues from keeping snapshots (other than the storage pool filling up maybe)? All the vm operations take into consideration snapshots. Storage is an issue, but so is every operation you'll make on the vm. When you have one image, the vm is handled only through this image. But when you have several, for each operation the right layer will search for the existence/ability to do the operation in all the snapshots (worst case). So there is in fact an impact, but it's due to the mere existence of the snapshots and their number, not their age. We support 26 snapshots per VM, but you should only use it if you actually need the backup. If you need RT performance, try to avoid it as possible.

Ryan, Disk snapshots consume fixed storage space (fixed since time of creation). The more differences there are from on your disk since the snapshot was taken, the more space is consumed, but that happens with no relation to the snapshot. If your frequent changes are in the form of adding data to you disks (on top of data snapshot time), then the space consumption of the snapshot is negligible. If you are undoing stuff from the snapshot time, there is actually more space consumed (to save the differences), otherwise the space would have just been released.

I assume the same would apply in reverse.

Re: [ovirt-users] oVirt/gluster storage questions for 2-3 node datacenter
I'll try to answer some of these.1) its not a serious problem persay the issue is if one node goes down and you delete a file while the second node is down it will be restored when the second node comes back which may cause orphaned files where as if you use 3 servers they will use quorum to figure out what needs to be restored or deleted. Further more your read and write performance may suffer especially in comparison to having 1 replica of the file with stripping.2) see answer 1 and just create the volume with 1 replica and only include the URI for bricks on two of the hosts when you create it.3) I think so but have never tried it you just have to define it as a local storage domain.4) well that's a philosophical question. You can theory have two hosted engines on separate VMs on two separate physical boxes but if for any reason they both go down you will "be living in interesting times" (as in the Chinese curse)5) YES!

I have 2 Intel hosts with SSD and magnetic disk and one AMD host with only magnetic disk. I have been trying to figure out the best way to configure my environment given my previous attempt with oVirt 3.3 encountered storage issues. I will be hosting two types of VMs - VMs that can be tied to a particular system (such as 3 node FreeIPA domain or some test VMs), and VMs which could migrate between systems for improved uptime. The processor issue seems straightforward. Have a single datacenter with two clusters - one for the Intel systems and one for the AMD systems. Put VMs which need to live migrate on the Intel cluster. If necessary VMs can be manually switched between the Intel and AMD cluster with a downtime. The Gluster side of the storage seems less clear. The bulk of the gluster with oVirt issues I experienced and have seen on the list seem to be two node setups with 2 bricks in the Gluster volume. So here are my questions:1) Should I avoid 2 brick Gluster volumes? 2) What is the risk in having the SSD volumes with only 2 bricks given that there would be 3 gluster servers? How should I configure them? 3) Is there a way to use local storage for a host locked VM other than creating a gluster volume with one brick? 4) Should I avoid using the hosted engine configuration? I do have an external VMware ESXi system to host the engine for now but would like to phase it out eventually. 5) If I do the hosted engine should I make the underlying gluster volume 3 brick replicated?Thanks in advance for any help you can provide. -David ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

I do not know what on_boot means in oVirt API, but it certainly is not passed to Vdsm or the guest, and as such cannot control what's in the guest's /etc/sysconfig/network-scripts/ifcfg-eth1. The guest may have ifcfg files, it may run NetworkManager, or it may be Ubunto or Windows. oVirt is responsible to exposing a (virtual) NIC to the guest, but does not interfere with its configuration.

Subject: [ovirt-users] Snapshot preview,clone and undo using ovirt api
Hi All,
In the ovirt admin panel, it is possible to do the following snapshots
actions
1. Clone
2. Preview
3. Undo
but i couldn't find out any direct api methods to do these actions, Is
it
possible to it using the ovirt api ?
Hi Shanil,
Preview/Undo actions can be invoked from VM context.
I.e.:
/api/vms/{vm_id}/preview_snapshot
/api/vms/{vm_id}/undo_snapshot
These actions are supported only on versions 3.4,
in older versions, use 'restore' (which is 'preview + commit'):
/api/vms/{vm_id}/snapshots/{snapshot_id}/restore
To clone a VM from snapshot, POST to /api/vms :
vm
...
snapshots
snapshot id={snapshot_id}/
/snapshots
...
/vm

Hi Shanil,
take a look here:
http://www.ovirt.org/Features/Single_Disk_Snapshot#REST-API
Maybe Allon or other can add some info if needed.

[ovirt-users] Real time network usages and IO usages of VM
Hi All, Is there any api methods to get the real time network usages and IO usages os of each vm ? I tried it by using api/vms/$id/statistics but its not getting the network and IO usages. Is it possible to get these details using the api calls ? -- Regards Shanil ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
