When I try to remove viritual disk from ovirt engine I get error "User admin@internal finished removing disk test_vm with storage failure in domain DATA_DOMAIN." VM itself was running fine with no errors. DATA_DOMAIN is GlusterFS replicated volume (on ovirt host). ovirt engine comp (fc19) ovirt-engine.noarch 3.3.0.1-1.fc19 ovirt host (fc19) vdsm.x86_64 4.12.1-4.fc19 vdsm-gluster.noarch 4.12.1-4.fc19 glusterfs-server.x86_64 3.4.1-1.fc19 tnx for help

[Users] Info on snapshot removal operations and final disk format
by Gianluca Cecchi 17 Nov '13

17 Nov '13

Hello, I'm on oVirt 3.2.3-1 on a Fedora 18 all-in-one test server. I have a Windows XP VM that has a disk in qcow2 format and has a snapshot on it. When I delete the snapshot I see, from the commands intercepted, that the final effect is to have a raw disk (aka preallocated) .... is this correct and always true? Does this mean that even if I create a VM with thin provisioned disks, as soon as I take at least one snapshot and I then delete it I only have raw disks? Or am I missing anything? This what I observed: as soon as I launch delete snapshot operation: raw format of new disk vdsm 30805 1732 6 13:24 ? 00:00:00 /usr/bin/dd if=/dev/zero of=/rhev/data-center/65c9777e-23f1-4f04-8cea-e7c8871dc88b/0a8035e6-e41d-40ff-a154-e0a374f264b2/images/75c54716-5222-4ad6-91f2-8b312eacc4b4/d4fa7785-8a89-4d13-9082-52556ab0b326_MERGE bs=1048576 seek=0 skip=0 conv=notrunc count=11264 oflag=direct after about 5 minutes: convert from qemu format to raw format vdsm 31287 1732 7 13:29 ? 00:00:08 /usr/bin/qemu-img convert -t none -f qcow2 /rhev/data-center/65c9777e-23f1-4f04-8cea-e7c8871dc88b/0a8035e6-e41d-40ff-a154-e0a374f264b2/images/75c54716-5222-4ad6-91f2-8b312eacc4b4/d4fa7785-8a89-4d13-9082-52556ab0b326 -O raw /rhev/data-center/65c9777e-23f1-4f04-8cea-e7c8871dc88b/0a8035e6-e41d-40ff-a154-e0a374f264b2/images/75c54716-5222-4ad6-91f2-8b312eacc4b4/d4fa7785-8a89-4d13-9082-52556ab0b326_MERGE at the end probably there is a rename of the disk file and qemu-img info /rhev/data-center/65c9777e-23f1-4f04-8cea-e7c8871dc88b/0a8035e6-e41d-40ff-a154-e0a374f264b2/images/75c54716-5222-4ad6-91f2-8b312eacc4b4/d4fa7785-8a89-4d13-9082-52556ab0b326 image: /rhev/data-center/65c9777e-23f1-4f04-8cea-e7c8871dc88b/0a8035e6-e41d-40ff-a154-e0a374f264b2/images/75c54716-5222-4ad6-91f2-8b312eacc4b4/d4fa7785-8a89-4d13-9082-52556ab0b326 file format: raw virtual size: 11G (11811160064 bytes) disk size: 9.5G # ll /rhev/data-center/65c9777e-23f1-4f04-8cea-e7c8871dc88b/0a8035e6-e41d-40ff-a154-e0a374f264b2/images/75c54716-5222-4ad6-91f2-8b312eacc4b4/ total 9995476 -rw-rw----. 1 vdsm kvm 1048576 Nov 16 12:09 6ac73ee2-6419-43a4-91e7-7d4ef2026943_MERGE.lease -rw-rw----. 1 vdsm kvm 11811160064 Nov 16 13:32 d4fa7785-8a89-4d13-9082-52556ab0b326 -rw-rw----. 1 vdsm kvm 1048576 Mar 23 2013 d4fa7785-8a89-4d13-9082-52556ab0b326.lease -rw-rw----. 1 vdsm kvm 1048576 Nov 16 13:29 d4fa7785-8a89-4d13-9082-52556ab0b326_MERGE.lease -rw-r--r--. 1 vdsm kvm 274 Nov 16 13:29 d4fa7785-8a89-4d13-9082-52556ab0b326.meta Thanks Gianluca

Without knowing how the disks are split among the controllers, I don't want to make any assumptions about how shared it actually is, since it may be half and half with no multipathing. While a multi-controller DAS array *may* be shared storage, it may not be. Moreover, I have no idea whether VDSM looks at by-path, by-bus, dm-*, or otherwise, and there are no guarantees that a SAS disk will present like a FC LUN (by-path/pci...-fc-$wwn...), whereas OCFS POSIXFS is assured to work, albeit with a more complex setup and another intermediary layer.

The array you have is the effective equivalent of attaching additional hard drives directly to your computer. It is not necessarily faster than iSCSI or Fiber Channel; almost any nearline storage these days will be SAS, almost all the SANs in production, and most of the tiered storage as well (because SAS supports SATA drives). I'm not even sure if NetApp uses FC-AL drives in their arrays anymore. I think they're all SAS, but don't quote me on that. What differentiates a SAN (iSCSI or Fiber Channel) from a NAS is that a SAN presents raw devices over a fabric or switched medium rather than point-to-point (point-to-point Fiber Channel still happens, but it's easier to assume that it doesn't for the sake of argument). A NAS presents network file systems (CIFS, GlusterFS, Lustre, NFS, Ceph, whatever), though this also gets complicated when you start talking about distributed clustered network file systems. Anyway, what you have is neither of these. It's directly-attached storage. It may work, but it's an unsupported configuration, and is only shared storage in the sense that it has multiple controllers. If I were going to configure it for oVirt, I would: Attach it to a 3rd server and export iSCSI LUNs from it Attach it to a 3rd server and export NFS from it Attach it to multiple CentOS/Fedora servers, configure clustering (so you get fencing, a DLM, and the other requisites of a clustered filesystem), and use raw cLVM block devices or GFS2/OCFS filesystems as POSIXFS storage for oVirt.

[Users] Low quality of el6 vdsm rpms
by Patrick Hurrelmann 16 Nov '13

16 Nov '13

Hi all, sorry for this rant, but... I now tried several times to test the beta 3.3.1 rpms, but they can't even be installed in the most times. One time it required a future selinux-policy, although the needed selinux fix was delivered in a much lower version. Now the rpms have broken requirements. It requires "hostname" instead of "/bin/hostname". This broken requirement is not included in the vdsm 3.3 branch, so I wonder where it comes from? Anyway. So I proceeded and tried to build vdsm myself once again. Currently the build fails with (but worked fine some days ago): /usr/bin/pep8 --exclude="config.py,constants.py" --filename '*.py,*.py.in' \ client lib/cpopen/*.py lib/vdsm/*.py lib/vdsm/*.py.in tests vds_bootstrap vdsm-tool vdsm/*.py vdsm/*.py.in vdsm/netconf vdsm/sos/vdsm.py.in vdsm/storage vdsm/vdsm vdsm_api vdsm_hooks vdsm_reg vdsm/storage/imageRepository/formatConverter.py:280:29: E128 continuation line under-indented for visual indent - How can the quality of the vdsm builds be increased? It is frustrating to spend time on testing and then the hosts cannot even be installed to broken vdsm rpms. - How are the builds prepared? Is there a Jenkins job that prepares "stable" rpms in addition to the nightly job? Or is this totally handcrafted? - How can it be that the rpm spec differs between the 3.3 branch and released rpms? What is the source/branch for el6 vdsm rpms? Maybe I'm just tracking on the wrong source tree...

Re: [Users] from irc
by Bob Doolittle 15 Nov '13

Hi, I had a question on IRC regarding sysprep/sealing of Windows VMs and use in Pools. Basically, if you follow the Quick Start Guide, it says to seal the VM and shut it down before making the Template. My problem with this is that when you start a VM from the Pool, it takes forever to unseal - i.e. to repersonalize itself. That's a bad experience from a VDI perspective - you want the user to get a desktop they can start using ASAP. Itamar responded to me directly via e-mail: > bobdrad: on your question of windows VMs from pool - you can start > them once with an admin for the sysprep to happen, then shut them down. > admin launch of VMs doesn't create a stateless snapshot and > manipulates the VM itself. This raises some questions. I'd love to understand this better. He's asked me to cross this conversation onto the Users list now. 1. My understanding is that a Pool clones VMs on demand from a template. So how does the admin "launch" the template? I thought the only way to exercise a pool is from the User Portal. Is it sufficient to do that as Admin? I thought the persistence only came when launching a VM from the Admin Portal. 2. My understanding of "sealing" a system is that this depersonalizes it - e.g. removes hostname, prepares network for reinitialization, etc. And that the next time the system boots up it re-personalizes. So if one were to restart it, even as admin, this would reverse the sealing process, which would seem to make sealing in the first place pointless. What am I missing? At the moment I don't see the point of sealing a VM before putting it into the Pool (assuming you're using DHCP, anyway). What happens if you don't? Thanks, Bob P.S. I note the behavior of Fedora vs RHEL 6 is quite different in this regard. If you follow the "sealing" process on the Quick Start page for Fedora it seems to have no visible effect, but on RHEL 6 it puts you through a re-personalization dialog which is rather extensive (and again, not really suitable for VDI use).

Hello, based on http://www.ovirt.org/Trusted_compute_pools_deployment#Provision_White_List_… The commands of kind: bash_oat_cert .. bash oat_oem ... are to be run on hypervisor host side, correct? Where can I find these packages for CentOS 6? Thanks in advance Gianluca PS: I took the time to correct a typo in client section where it said "Yum Install oat server package from fedora19 repository" instead of "Yum Install oat client package from fedora19 repository"

[Users] Change data domain
by Juan Pablo Lorier 15 Nov '13

15 Nov '13

Hi, I'm changing the master domain to a new added one. I've placed the old in maintenance and ovirt made the change of master to the new one. The thing is that now that I have both active, I get this error: Sync Error on Master Domain between Host Dell2 and oVirt Engine. Domain: IBM3300 is marked as Master in oVirt Engine database but not on the Storage side. Please consult with Support on how to fix this issue. How can I fix this? Another thing, is there a way of having two iscsi data domains mirrored? To have a sort of high availability in the data domains. Regards,

[Users] Problems with first time oVirt installation
by Lindsay Mathieson 15 Nov '13

15 Nov '13

Hi all - trying to evaluate ovirt and having real problems with getting a self contained install running. I've followed the Quickstart guide at: http://www.ovirt.org/Download word for word using a fresh CentOS 6.4 install with all updates applied on a Intel based PC with 8GB Ram and two nics. It seems to all go well but when I get into the web interface, none of the storage is initially visible, neither the ISO_DOMAIN nor the local storage. Oddly if I refresh the browser (firefox & chrome) while on the storage page the ISO_DOMAIN appears but can't be attached to a datacenter - "None Available" If I go into the host page the host is there but not finished configuring. The network setup is unfinished, the management interface is not attached to a NIC. If I attach it to the active nic (NIC 0) it throws an exception on Save. I can attach it to nic 1 but its not actually hooked up to anything. I have successfully installed and run proxmox on this pc, so don;t think there are hardware problems. On a related note - I've also been trying to test ovirt at home, which means running it on KVM (setup with virt-manager). CentOS installs fine but on reboot just goes to a black screen with the hour glass. If anyone has suggestions on how to get past that it would help my test config a lot :) Host machine is Kubuntu 13.10. Thanks, -- Lindsay

[Users] Gluster RDMA support
by Murphy-Olson, Daniel E. 15 Nov '13

15 Nov '13

Hi all, I'm trying to configure a gluster storage pool over RDMA protocol. I created the volume by hand, because RDMA is disabled in the volume creation interface due to a patch ~18 months ago. After the manual creation of the volume, it displays bot protocols as being configured.. However, in the XML configuration that is generated for libvirt, ?protocol=rdma is not appended to the path. Is there some template I can edit to add that, or is it buried in the code somewhere? I cannot seem to find where the vsdm clients are getting the url for the gluster volume. Thanks! ---- Daniel Murphy-Olson Systems Administrator Mathematics & Computer Science Division Argonne National Laboratory 630-252-0055

[Users] Failed to start JBoss AS
by Bob Doolittle 15 Nov '13

15 Nov '13

Hi, I had a working engine, using 3.3.0 on Fedora 19. I rebooted my engine, and JBoss AS won't come back up. I get the attached errors from server.log. Has anyone seen this before? Any suggestions on how to recover? How I got here: I had a working Engine (mach1 F19) and Host (mach2 F19), but needed to play some musical chairs with my hardware to utilize a 3rd machine (mach3 RH6). My goal is to have mach2 become Engine, and mach3 Host. I did the following: 1. Created an NFS share on mach3, and used it as NFS Export Storage from mach2. 2. Exported my VMs and templates to the Export storage. 3. Removed mach2 from my Datacenter 4. Shut down mach1 5. Installed fresh F19 on mach2 (my old host), and installed Engine 3.3.0 on it 6. Added mach3 as Host 7. Imported my VMs and Templates from the Export Storage At this point all looked well. I rebooted mach2, but it won't come back up. I'd appreciate any insight. Thanks, Bob

Hello, I've trying to move a 32bit CentOS 6.4 on VirtualBox to oVirt on Fedora 19 64bit via virt-v2v. The command I'm currently using is: virt-v2v -i libvirtxml -of qcow2 -oa sparse -o rhev -osd xxx.xxx.xxx.xxx:/usr/local/ovirt/exports --network ovirtmgmt /usr1/home/williams/Downloads/OpenAthens/VMs/OpenAthensLARuntime2.2.xml The exciting bit of the XML is: <devices> <emulator>/usr/bin/qemu-kvm</emulator> <disk type='file' device='disk' snapshot='no'> <source file='/usr1/home/williams/Downloads/OpenAthens/VMs/OpenAthens_LA_Runtime_2.2.img'/> <target dev='vda' bus='virtio'/> <alias name='virtio-disk0'/> </disk> </devices> The image is a RAW (taken from the working VirtualBox install) but I have tried the original image with the same result: virtio configured, but no virtio kernel found at /usr/share/perl5/vendor_perl/Sys/VirtConvert/Converter/RedHat.pm I have looked at the code: /usr/share/perl5/vendor_perl/Sys/VirtConvert/Converter/RedHat.pm:~490 creating this and dumped the contents of the grub look up: Sys::VirtConvert::GuestfsHandle=HASH(0x433da98)< >/dev/VolGroup/lv_root< $VAR1 = bless( { 'onclose' => [ sub { "DUMMY" } ], 'g' => bless( { '_g' => 70645888, '_flags' => 0 }, 'Sys::Guestfs' ) }, 'Sys::VirtConvert::GuestfsHandle' ); If I tell the code to skip this section the result becomes: virt-v2v: Failed to find a kernel_pkg.i686 package to install Any ideas on how to solve this or what the solution might, please?

[Users] Snapshot delele/merge broken. Was: Live storage migration snapshot removal (fails)
by Sander Grendelman 14 Nov '13

14 Nov '13

Snapshot deletion on preallocated FC domain disks is broken in ovirt-stable/3.3 Both online and offline snapshot deletion leads to an error and the snapshot state is changed to "BROKEN". When I apply the patch at http://gerrit.ovirt.org/#/c/19983/ from https://bugzilla.redhat.com/show_bug.cgi?id=1015071 snapshot deletion works again. Can/will this patch be backported to ovirt-stable?

[Users] Custom settings for Kernel Same-page Merging (KSM)?
by Frank Wall 14 Nov '13

14 Nov '13

Hi, recently I've noticed that ksmd is using quite a lot CPU on my oVirt node. While I have plenty RAM, my CPU is way slow. Thus ksmd is eating up the most limited ressource here. Is it supported to use custom settings for ksmd? I've noticed that it is handled by MoM: /etc/vdsm/mom.d/03-ksm.policy. May I just change some settings here, or is there a tuning parameter in oVirt engine? Couldn't find a matching one with engine-config. I'd like to use a higher value for sleep_millisecs to reduce CPU usage (with the possible side effect of higher RAM usage). Thanks - Frank

[Users] Installing Windows VMs
by Bob Doolittle 14 Nov '13

14 Nov '13

In the QuickStart Guide, it implies that you should find a virtual floppy image for virtio-win in the ISO_DOMAIN. Or at least I can find no information on where to find/populate that image before the Guide shows its use. However, in my default 3.3 installation, there was nothing pre-populated in my ISO_DOMAIN. Should there have been? Regards, Bob

Re: [Users] Default route on hosts
by Assaf Muller 14 Nov '13

14 Nov '13

Can users outside of the hosts' networks reach the VMs in the hosts? If you use netstat -rn it is expected that the gateway will be 0.0.0.0, as ifcfg-ovirtmgmt has DEFROUTE=yes and ifcfg-public has DEFROUTE=no, then ovirtmgmt's 'gateway' (0.0.0.0) will be determined as the host's default gateway. However with the new multiple gateways feature we configure source routing to make sure that traffic that comes (from the outside) in the public network's device will return the way it came in. You can use 'ip rule' to see the rules VDSM configures. It creates two rules and a routing table per device. You can use 'ip route show table %s' on each table, where the IDs can be obtained by 'ip rule'. ----- Original Message ----- From: "Chris Geddings" <chris.geddings(a)duke.edu> To: "Assaf Muller" <amuller(a)redhat.com> Sent: Tuesday, November 12, 2013 2:26:40 PM Subject: Re: [Users] Default route on hosts On Nov 12, 2013, at 3:32 AM, Assaf Muller <amuller(a)redhat.com> wrote: > oVirt 3.3 introduced a feature called multiple gateways which may assist you.

Now, my management network has a gateway of 0.0.0.0, as it is a completely simple network, so that may be part of the problem. I'm not sure the impact of a 0.0.0.0 as a gateway. I'm not sure how to poke at this further to figure out where the breakage is. Routing looks like it has gotten a little more complex, and I'm still operating with 'netstat -rn' and 'route add foo' type commands. --Chris

[Users] Bug: adding LocalStorage Data Centers
by Sven Kieske 14 Nov '13

14 Nov '13

Hi, affected version: oVirt 3.3 (ManagementNode) how to reproduce: setup 2 data centers with local storage, add data master storage domains to these 2 data centers add another data center with local storage, try to add another master storage domain. expected result: the data domain gets created just like the 2 before actual result: ovirt management complains that the data domain already exists, which is not true. This behaviour was introduced with version 3.3, we didn't see this in version 3.2 This is regardless of node versions. I would at first like to know if anybody can reproduce this? If this is the case I would create a bugzilla entry. Regards Sven
