Re: [Users] Disk move when VM is running problem
From the email above, 'lvs' shows that the "d477fcba-2110-403e-93fe-15565aae5304" is not physically migrated to the target storage domain "14b5167c-5883-4920-8236-e8905456b01f".

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.

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).

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.

I think vdsm domains do have their own meta-data except the lvm or posix file system meta data. If you want to be extra careful you can always put the export domain in maintenance before the extend :) If the export domain come back to life, I think the domain meta data should be invalidated after the extend.

Re: [Users] 关于ovirt 3.2支持glusterfs问题
Let me help to translate those characters below. --- I installed oVirt 3.2 on my system and used "engine-setup" to create a new engine server. In the question process of "engine-setup", the different answeres for storage type made the different results. If "glusterfs" type was chosen, the data center was not created and the storage domain could not be added neither. If "both" was chosen, there was no gluster-fs type when adding a data center, only other types listed. If "posix compliant fs" was chosen, adding glusterfs volume failure was shown in the WEB UI. However, the gluster volume was successfully created in the node shown by "gluster volume info". Any clues? --- Dave Neary: Hi, I'm sorry, this is an English language mailing list, and I do not speak Chinese. Google translate suggests that your question relates to an installation issue - you installed oVirt 3.2, ran engine-setup, selected a POSIX FS type data center, and do not see any storage domain.

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 ?

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

Could it be that you are using an ancient libvirt with no
virDomainMigrateToURI2? What are your libvirt and qemu-kvm
versions (on
both machines)?

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] 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. I hope that someone can show me what is the problem. If you need more information aboout the installation I can show it.

Re: [Users] trouble with pci passthrough
2013-1-10 8:42, ahuser: Hi Itamar, Thanks for your reply. I tried and ro this with virsh + xml file and virt-manager. I suppose you assigned the device to the virtual server successfully with virsh and virt-manager. Confusing is that after the installation oVirt the device is not passed cleanly. Do you mean the old virtual server which was created before oVirt installation was finally managed by oVirt? Or oVirt didn't manage this virtual server but the PCI device assigned to the virtual server disappeared?

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] 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.

Re: [Users] VM has paused due to unknown storage error
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] ovirt & iscsi mulitpath
2012Jorick Astrego: Dear all, After some problems I have my ovirt setup running now. But I run into a new problem with the network configuration. We have a quad nic with 4 gigabit connections over 2 switches (2X2) and an active/passive iscsi SAN. The first is connected to switch 1 and the second to switch 2 with a 10Gbe link. Do you mean you have a host(ovirt node) with a quad nics conneting to switches? And one SAN connecting to the switch 1 in another side, the other SAN conecting to switch 2 with a 10Gbe lnk? I think a picture will make the text description more comprehensive. Now I would like to use iSCSI multipathing instead of bonding but I cannot use the same vlan for multiple storage networks and I cannot assign the same storage network to several nic's. I could use bonding, but we use 4 links over 2 switches and if I read everything correctly bonding only works through a single switch. How do other people achieve this? -- --- 舒明 Shu Ming Open Virtualization Engineerning; CSTL, IBM Corp.

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."

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. I'm not sure if this is the right or good way tho fix this problem (sorry for my bad english I hope this is understandable) ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users -- --- ??

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. Most of the others have serious drawbacks, so I wanted to know if anyone had a silver bullet before I put more time into it.

Re: [Users] Can oVirt be installed in a virtual machine?
? 2012-9-13 1:26, Nicolas Chenier: Hi all, I am starting a small hosting business and want to use oVirt w/ KVM as my virtualization platform. I currently have 2 host servers and an iSCSI NAS. Do I need a dedicated machine to run oVirt? Can I run it from a VM? Of course you can install ovirt-engine on a VM. Can I use the all-in-one solution in a Production environment, with a 2nd host? ... would I need to install oVirt on both hosts, in the event that one of my servers went down? I do not recommend to use all-in-on solution in a Production environment. You need to install ovirt-engine on one host(might be your desktop) and install VDSM on the two host servers. ovirt-engine doesn't support HA yet, so you need only one ovirt-engine. I am trying to see how I can survive if my oVirt server fails. It would be great if it ran from a VM but I can also see issues with doing that... Another option would be to run oVirt on my workstation and have it connect to my 2 host servers in colocation over the internet? For ovirt-engine installation, 4G plus memory is recommended. So you can start a VM with more than 4G memory and install ovirt-engine on that, also make sure ovirt-engine can connect the two host servers over the internet.

Re: [Users] host raiding two LUN from different external storage

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 .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] 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.

Also, I hit a bug to resume the VM after the snapshot was done. The VM was always in pause state after I clicked the resume button after the snapshot was done. I looked into the VM by VNC and VNC console showed that the VM was in frozen state. Has anyone seen these or has it been fixed in the upstream? other problem is the VM must be paused when the snapshot is undergoing.

Re: [Users] oVirt 3.1 - Error adding host , incorrect vdsm version
I encountered this error in oVirt 3.1 beta release testing. And I changed the vdsm-bootstrap.py in engine similar to the below and it worked. I am also wondering why this bug was not exported to other people. It seems that ovirt node can ignore the vds_bootstrap script running on itself by someway. That maybe the reason the bug was not hit. On 2012-6-20 0:08, Ofer Schreiber wrote: Just checked this issue with latest ovirt-engine on F17 (with vdsm 4.10), and didn't encounter this issue at all.

Subject: [Users] The SPM host node is in unresponsive mode
Hi,
I attached one host node in my engine. Because it is the only one
node, it is automatically the SPM node. And it used to run well in
my
engine. Yesterday, some errors happened in the network work of the
host
node. That made the node become "unresponsive" in the engine. I am
sure the network errors are fixed and want to bring the node back to
life now. However, I found that the only one node could not be
"confirm as host been rebooted" and could not be set into the
maintenance mode. The reason given there is no active host in the
datacenter and SPM can not enter into maintenance mode. It seems
that
it fell into a logic loop here. Losting network can be quite common
in
developing environment even in production environment, I think we
should
have a way to address this problem on how to repair a host node
encountering network down for a while.
Hi Shu,
first, for the manual fence to work ("confirm host have been rebooted") you
will need
another host in the cluster which will be used as a proxy and send the actual
manual fence command.
second, you are absolutely right, loss of network is a common scenario, and we
should be able
to recover, but lets try to understand why your host remain unresponsive after
network returned.
please ssh to the host and try the following:
- vdsClient -s 0 getVdsCaps (validity check making sure vdsm service is up and
running and communicate with its network socket from localhost)
[root@ovirt-node1 ~]# vdsClient -s 0 getVdsCaps

It seems that VDSM process was gone while libvirtd spawned by VDSM was
there. 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. The latest message

[HA] problem is systemctl doesn't show real reason why service didn't go, lets
try the following:
- # cd /lib/systemd/
- # ./systemd-vdsmd restart
[root@ovirt-node1 systemd]# ./systemd-vdsmd start

Stopping network (via systemctl): [ OK ]
Starting network (via systemctl): Job failed. See system logs and
'systemctl status' for details.
[FAILED]
Starting up vdsm daemon:
vdsm start [ OK ]
I did futher test on this system. After I killed the solo libivrtd
process, vdsm processs can be started without libvirtd. However, vdsm
can not work either in this way. After several round of "killall
libvirtd", "service vdsmd start", "vdsmd stop", both vdsm and
libivirtd processs now start. In summary:
1) the libvirtd started by vdsm process may stand there even after its
parent vdsm process is gone.
2) the legacy libvirtd may block the start process of vdsm service
3) vdsm service can work with the legacy libvirtd sometime without
creating a new one.
Here are my service process in the host node, please notice that the
libvirtd process is earlier than the vdsm process that means this
libvirtd was a legacy process not created by the vdsm process in this round.
The problem still exist in engine that I don't have a way to reactivate
the host node.

Subject: [Users] The SPM host node is in unresponsive mode
Hi,
I attached one host node in my engine. Because it is the only one
node, it is automatically the SPM node. And it used to run well in
my
engine. Yesterday, some errors happened in the network work of the
host
node. That made the node become "unresponsive" in the engine. I am
sure the network errors are fixed and want to bring the node back to
life now. However, I found that the only one node could not be
"confirm as host been rebooted" and could not be set into the
maintenance mode. The reason given there is no active host in the
datacenter and SPM can not enter into maintenance mode. It seems
that
it fell into a logic loop here. Losting network can be quite common
in
developing environment even in production environment, I think we
should
have a way to address this problem on how to repair a host node
encountering network down for a while.
Hi Shu,
first, for the manual fence to work ("confirm host have been rebooted") you
will need
another host in the cluster which will be used as a proxy and send the actual
manual fence command.
second, you are absolutely right, loss of network is a common scenario, and we
should be able
to recover, but lets try to understand why your host remain unresponsive after
network returned.
please ssh to the host and try the following:
- vdsClient -s 0 getVdsCaps (validity check making sure vdsm service is up and
running and communicate with its network socket from localhost)
- please ping between host and engine
- please make sure there is no firewall on blocking tcp 54321 (on both host and
engine)
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.

[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?

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 Ming IBM China Systems and Technology Laboratory ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [Users] Ovirt Engine as a VM
On 2012-2-19 2:16, Nathan Stratton wrote: Had anyone created a how to or notes on how to manage an ovirt engine as a guest on the cluster? 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? <> Nathan StrattonCTO, BlinkMind, Inc. nathan at robotics.net nathan at blinkmind.com http://www.robotics.nethttp://www.blinkmind.com ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users -- Shu Ming IBM China Systems and Technology Laboratory ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
