HI, I have centos 7.1 latest update for hosts and VM that hosts the hosted engine, the hosted engine uses iSCSI storage and so far it is working correctly *as expected* , I have 1 shared DC, 1 Cluster and trying to add GFS2 storage as a master data domain, I am using corosync , pacemaker , pcs to manage the DLM and cLVM that is also working as expected, however whenever I try to add the GFS2 storage I get the following error message from VDSM.log ————— Thread-884::ERROR::2015-05-08 11:45:59,291::sdc::154::Storage.StorageDomainCache::(_findUnfetchedDomain) looking for domain 2435cdc4-61eb-4ad6-9669-e900f13b7f1d Thread-884::DEBUG::2015-05-08 11:45:59,291::lvm::371::Storage.OperationMutex::(_reloadvgs) Operation 'lvm reload operation' got the operation mutex Thread-884::DEBUG::2015-05-08 11:45:59,295::lvm::291::Storage.Misc.excCmd::(cmd) /usr/bin/sudo -n /sbin/lvm vgs --config ' devices { preferred_names = ["^/dev/mapper/"] ignore_suspended_devices=1 write_cache_state=0 disable_after_error_co unt=3 obtain_device_list_from_udev=0 filter = [ '\''a|/dev/mapper/CETUSRAID1E0A04V01|/dev/mapper/CETUSRAID1E0A04V02|/dev/mapper/CETUSRAID3E0A01V01|'\'', '\''r|.*|'\'' ] } global { locking_type=1 prioritise_write_locks=1 wait_for_locks =1 use_lvmetad=0 } backup { retain_min = 50 retain_days = 0 } ' --noheadings --units b --nosuffix --separator '|' --ignoreskippedcluster -o uuid,name,attr,size,free,extent_size,extent_count,free_count,tags,vg_mda_size,vg_mda_free,lv_c ount,pv_count,pv_name 2435cdc4-61eb-4ad6-9669-e900f13b7f1d (cwd None) Thread-884::DEBUG::2015-05-08 11:45:59,397::lvm::291::Storage.Misc.excCmd::(cmd) FAILED: <err> = ' Volume group "2435cdc4-61eb-4ad6-9669-e900f13b7f1d" not found\n Cannot process volume group 2435cdc4-61eb-4ad6-9669-e900f13b7f1d\n'; <rc> = 5 Thread-884::WARNING::2015-05-08 11:45:59,400::lvm::376::Storage.LVM::(_reloadvgs) lvm vgs failed: 5 [] [' Volume group "2435cdc4-61eb-4ad6-9669-e900f13b7f1d" not found', ' Cannot process volume group 2435cdc4-61eb-4ad6-9669-e900f13b7f1d '] Thread-884::DEBUG::2015-05-08 11:45:59,401::lvm::416::Storage.OperationMutex::(_reloadvgs) Operation 'lvm reload operation' released the operation mutex Thread-885::DEBUG::2015-05-08 11:45:59,403::__init__::298::IOProcessClient::(_run) Starting IOProcess...

Directly connect NIC or other cards to VM?
by David Smith 11 May '15

11 May '15

Is there a way to directly connect a specific device (ie, NIC) to a particular VM? I've figured out how to map a specific network interface to a VM, thats one step, but in the end I may need direct access to the PCI device itself. Second to that, for network interfaces mapped to a particular VM, is there a way for the VM to be able to properly detect physical link state of that interface? Right now that's a 'configurable option' inside network interface settings on the VM in the manager (ie, plugged, not plugged, and link state up /down) Thanks, David

how to delete the default cluster?
by Nathanaël Blanchet 11 May '15

11 May '15

Hello, I'd like to remove the default cluster, but engine refuses telling me that the blank template is associated to it. The problem is that all my vms (nearly 200) are created on the base of that template, so I can't first remove it. Is there a workaround to do this? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Is it mandatory to have fixed IP addres for eth0, for installtion of OVirt
by John Joseph 10 May '15

10 May '15

Dear All, As for experimental purpose I have done OVirt installation on CentOS 6.6 and it was success. Till now before installation of OVirt, I used to make the eth0 IP permanent and then install Now I have need to take the machine to different places to demo and discuss about the installation, In this case I need to keep my eth0 on DHCP. Was wondering whether the fixed IP address of eth0 is mandatory or can I use dhcp for the host machine, before installing Ovirt thanks Joseph John

Clone a Snapshot with REST
by Jon Disterhoft 08 May '15

08 May '15

Hello All, I'm trying to create VM backups through the REST API using curl. My understanding of this flow is to create a snapshot, clone the snapshot, then export the clone machine. I've got the snapshot part working: curl -v --insecure -u "admin@internal:<mypass>" -H "Content-type: application/xml" -X POST https://<myserver>/api/vms/e7d53832-b1ba-4f6e-8218-6116a0b4ea53/snapshots -d ' <snapshot> <vm id="e7d53832-b1ba-4f6e-8218-6116a0b4ea53"/> <description>TEST_SNAPSHOT</description> <disks> <disk id="057c80e5-701f-4dcf-a86d-a89672ff606a"/> </disks> </snapshot>' However, I can't figure out how to get the clone portion working. I've found a reference to it, but am unable to make it work: > To clone a VM from snapshot, POST to /api/vms : > <vm> > ... > <snapshots> > <snapshot id={snapshot_id}/> > </snapshots> > ... > </vm> So the question is, how do you clone a snapshot with the REST API? Also, is there a complete listing anywhere of all features/action supported by the REST API?

adding LINKDELAY to ovirtmgmt when vdsm configures it
by Jason Keltz 07 May '15

07 May '15

Hi. Is it possible through engine to specify configuration parameters for network interfaces that must be passed through on initialization? For example, I need em1 and em2 configured with "LINKDELAY=10". I can add it after the fact, but I don't want to do that. I want vdsm to configure the interface with that setup already the first time. Jason.

Get involved in oVirt project! May edition
by Sandro Bonazzola 07 May '15

07 May '15

Hi, have you got some free time and do you want to get involved in oVirt project? Do you like the idea of having fresh disk images of recent distribution in oVirt Gluster repository? You can help us by testing existing online images (like https://getfedora.org/en/cloud/download/) ensuring they works with cloud-init or creating one yourself and report your success to devel(a)ovirt.org. We'll be happy to upload the images once these are ready. Do you like Debian and do you have some programming skill? Help us getting VDSM running on it! Debian Jessie has been released a couple of weeks ago and it's a good time for giving it a try. You can follow the progress here: http://www.ovirt.org/VDSM_on_Debian Here are some bugs you can hopefully fix in less that one day or you can just try to reproduce providing info: Bug ID Status Whiteboard Summary 1065350 POST integration hosted-engine should prompt a question at the user when the host was already a host in the engine 1059952 NEW integration hosted-engine --deploy (additional host) will fail if the engine is not using the default self-signed CA 1083104 ASSIGNED integration engine-setup --offline does not update versionlock Do you want something easier?

selectively disabling IPv6 on bridges
by Rik Theys 07 May '15

07 May '15

Hi, I'm looking for a way to selectively disable IPv6 on the bridge interfaces on the oVirt hosts. When oVirt creates the bridges for all logical networks on the host, it keeps the default settings for IPv6 which means all bridges get a link-local address and accept router advertisements. When a VM is created on the logical network, it can now reach the host over IPv6 (but not over IPv4 if no IP address has been assigned on the host). If it sends out a router advertisement it can even create a global IPv6 address (haven't tested this). How can I prevent this? I would like to prevent the guest from IPv6 access to the host but the guest itself still needs IPv6 access (global IPv6 addresses). Is it sufficient to create a sysctl config file that says: net.ipv6.conf.default.disable_ipv6 = 1 ? Regards, Rik -- Rik Theys System Engineer KU Leuven - Dept. Elektrotechniek (ESAT) Kasteelpark Arenberg 10 bus 2440 - B-3001 Leuven-Heverlee +32(0)16/32.11.07 ---------------------------------------------------------------- <<Any errors in spelling, tact or fact are transmission errors>>

Hi!, I've been migrating my Ovirt storage from iscsi to Gluster. What I've been doing is moving the disks with the VM powered off. This procedure was fine until I tried to migrate a 100GB disk from a VM with an Oracle DB. During this migration the access to Gluster slowed down, affecting the whole cluster (VDSM timeout in oVirt Engine, VM's entered in unknown state, gluster client disconnected from a brick) What I found in gluster servers was a XFS error: XFS: possible memory allocation deadlock in kmem_alloc (mode:0x250) And this error is due to the number of extents of the file (~ 8M): gluster01:/gluster/ovirt1_brick_01/brick/89c4e113-1003-4b4e-850e-e7fc5bf2edc6/images/e5b7fc46-4168-4019-a13a-f9b7093d0534# > xfs_bmap f9cd555d-fd98-499f-a853-d0ce76eecd37 | wc -l > 8627613 > I'm using Gluster 3.6.2 and Centos 7 (3.10.0-229.1.2.el7.x86_64 kernel). Does anyone know why is qemu-img generating this so fragmented file?
