------=_Part_51316288_608143832.1472587678781 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit I've got Cinder configured and pointed at Ceph for it's back end storage. I can run ceph commands on the cinder machine and cinder is configured for noauth and I've also tried it with Keystone for auth. I can run various cinder commands and it'll return as expected. When I configure it in oVirt it'll add the external provider fine, but when I go to create a disk it doesn't populate the volume type field, it's just empty. The corresponding command for cinder: cinder type-list and cinder type-show <name> returns fine and it is public. Ovirt and Cinder are on the same host so it isn't a firewall issue.

Mailing-Lists upgrade

This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --IfGqXrbgT9wNNdIsvS8kI8WdhEQHlgkiq Content-Type: multipart/mixed; boundary="AUFHCWPQQknM84fF2kF4uGjIv4blC9bMv"; protected-headers="v1" From: =?UTF-8?B?TWFyYyBEZXF1w6huZXMgKER1Y2sp?= <duck(a)redhat.com> To: oVirt Infra <infra(a)ovirt.org>, users <users(a)ovirt.org>, devel <devel(a)ovirt.org> Message-ID: <c5c71fce-0290-e97a-ddd0-eab0e6fccea4(a)redhat.com> Subject: Mailing-Lists upgrade --AUFHCWPQQknM84fF2kF4uGjIv4blC9bMv Content-Type: text/plain; charset=utf-8 Content-Language: en-US Content-Transfer-Encoding: quoted-printable Quack, On behalf of the oVirt infra team, I'd like to announce the current Mailing-Lists system is going to be upgraded to a brand new Mailman 3 installation on Monday during the slot 11:00-12:00 JST. It should not take a full hour to migrate as we already made incremental synchronization with the current system but better keep some margin. The system will then take over delivery of the mails but might be a bit slow at first as it needs to reindex all the archived mails (which might take a few hours). To manage your subscriptions and delivery settings you can do this easily on the much nicer web interface (https://lists.ovirt.org) There is a notion of account so you don't need to login separately for each ML.= You can Sign In using Fedora, GitHub or Google or create a local account if you prefer. Please keep in mind signing in with a different method would create separate accounts (which cannot be merged at the moment). But you can easily link your account to other authentication methods in your settings (click on you name in the up-right corner -> Account -> Account Connections). As for the original mail archives, because the previous system did not have stable URLs, we cannot create mappings to the new pages. We decided to keep the old archives around on the same URL (/pipermail), so the Internet links would still work fine. Hope you'd be happy with the new system. \_o< --AUFHCWPQQknM84fF2kF4uGjIv4blC9bMv-- --IfGqXrbgT9wNNdIsvS8kI8WdhEQHlgkiq Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEcpcqg+UmRT3yiF+BVen596wcRD8FAlmwx0MACgkQVen596wc RD9LTQ/+LtUncsq9K8D/LX8wqUTd6VyPwAD5UnAk5c3H/2tmyVA0u7FIfhEyPsXs Z//LE9FEneTDqDVRi1Dw9I54K0ZwxPBemi71dXfwgBI7Ay0ezkbLWrA168Mt9spE tHAODEuxPt2to2aqaS4ujogrkp/gvEP8ILoxPEqoTPCJ/eDTPAu/I1a2JzjMPK3n 2BBS6D8z0TLAf7w1n72TsgX2QzJW57ig/0HELyjvat2/K8V3HSrkwiKlsdULQDWe zB+aMde7r6UoyVKHqlu4asTl2tU/lGZ+e31Hd9Bnx1/oZOJdzslGOhEo9Qoz6763 AHWU9LKiK4NtxYHj2UQTWhndr8PiTtTmR73eIDmkb0cuRXxzjl9VQbwYJ0Kbrmfp attTqpc2CnEojTNXUUNSmNxotZoYXZiX8ZvjPfSgRVr15TUYujzlOfG+lUynbQMV 9rQ9/m58wgwYUymMpOIsRGaIcAKzjm+WpuuVnO+bS2AfmcBkGMQRoIhfV+3SkS8q kT9cDXgcDZOzVFcnZZB4EjbycMcPgZDcoHxU88VdYH+jFJYvvb21esgswVF/wJ2Z uEI/chp4+ADaQhl8ehZNWMSZq125v6SeirPhBNgLG7zFVZI1S9Tm/6qFmH+ajQY7 nCk1X9HZlB1ubex1X+HibRz9QKOilkMgkADyJ4yMDckwYj93sx0= =l6uN -----END PGP SIGNATURE----- --IfGqXrbgT9wNNdIsvS8kI8WdhEQHlgkiq--

vdsClient is removed and replaced by vdsm-client
by Irit Goihman 16 Apr '18

16 Apr '18

Hi All, vdsClient will be removed from master branch today. It is using XMLRPC protocol which has been deprecated and replaced by JSON-RPC. A new client for vdsm was introduced in 4.1: vdsm-client. This is a simple client that uses JSON-RPC protocol which was introduced in ovirt 3.5. The client is not aware of the available methods and parameters, and you should consult the schema [1] in order to construct the desired command. Future version should parse the schema and provide online help. If you're using vdsClient, we will be happy to assist you in migrating to the new vdsm client. *vdsm-client usage:* vdsm-client [-h] [-a ADDRESS] [-p PORT] [--unsecure] [--timeout TIMEOUT] [-f FILE] namespace method [name=value [name=value] ...] Invoking simple methods: # vdsm-client Host getVMList ['b3f6fa00-b315-4ad4-8108-f73da817b5c5'] For invoking methods with many or complex parameters, you can read the parameters from a JSON format file: # vdsm-client Lease info -f lease.json where lease.json file content is: { "lease": { "sd_id": "75ab40e3-06b1-4a54-a825-2df7a40b93b2", "lease_id": "b3f6fa00-b315-4ad4-8108-f73da817b5c5" } } It is also possible to read parameters from standard input, creating complex parameters interactively: # cat <<EOF | vdsm-client Lease info -f - { "lease": { "sd_id": "75ab40e3-06b1-4a54-a825-2df7a40b93b2", "lease_id": "b3f6fa00-b315-4ad4-8108-f73da817b5c5" } } EOF *Constructing a command from vdsm schema:* Let's take VM.getStats as an example. This is the entry in the schema: VM.getStats: added: '3.1' description: Get statistics about a running virtual machine. params: - description: The UUID of the VM name: vmID type: *UUID return: description: An array containing a single VmStats record type: - *VmStats namespace: VM method name: getStats params: vmID The vdsm-client command is: # vdsm-client VM getStats vmID=b3f6fa00-b315-4ad4-8108-f73da817b5c5 *Invoking getVdsCaps command:* # vdsm-client Host getCapabilities Please consult vdsm-client help and man page for further details and options.

Passing VLAN trunk to VM
by Simon Vincent 26 Mar '18

26 Mar '18

Is it possible to pass multiple VLANs to a VM (pfSense) using a single virtual NIC? All my existing oVirt networks are setup as a single tagged VLAN. I know this didn't used to be supported but wondered if this has changed. My other option is to pass each VLAN as a separate NIC to the VM however if I needed to add a new VLAN I would have to add a new interface and reboot the VM as hot-add of NICs is not supported by pfSense.

HostedEngine with HA
by Carlos Rodrigues 22 Mar '18

Hello, I have one cluster with two hosts with power management correctly configured and one virtual machine with HostedEngine over shared storage with FiberChannel. When i shutdown the network of host with HostedEngine VM, it should be possible the HostedEngine VM migrate automatically to another host? What is the expected behaviour on this HA scenario?

oVIRT 4.1 / iSCSI Multipathing
by Devin Acosta 05 Mar '18

05 Mar '18

I am using the latest release of oVIRT 4.1.3, and I am connecting a Dell Compelent SAN that has 2 fault domains each on a separate VLAN that I have attached to oVIRT. From what I understand I am suppose to go into “iSCSI Multipathing” option and add a BOND of the iSCSI interfaces. I have done this selecting the 2 logical networks together for iSCSI. I notice that there is an option below to select Storage Targets but if I select the storage targets below with the logical networks the the cluster goes crazy and appears to be mad. Storage, Nodes, and everything goes offline even thought I have NFS also attached to the cluster. How should this best be configured. What we notice that happens is when the server reboots it seems to log into the SAN correctly but according the the Dell SAN it is only logged into once controller. So only pulls both fault domains from a single controller. Please Advise. Devin

when creating VMs, I don't want hosted_storage to be an option
by Mike Farnam 09 Feb '18

09 Feb '18

Hi All - Is that a way to mark hosted_storage somehow so that it’s not available to add new VMs to? Right now it’s the default storage domain when adding a VM. At the least, I’d like to make another storage domain the default. Is there a way to do this? Thanks

qemu-kvm images corruption
by Nicolas Ecarnot 06 Feb '18

06 Feb '18

TL;DR: How to avoid images corruption? Hello, On two of our old 3.6 DC, a recent series of VM migrations lead to some issues : - I'm putting a host into maintenance mode - most of the VM are migrating nicely - one remaining VM never migrates, and the logs are showing : * engine.log : "...VM has been paused due to I/O error..." * vdsm.log : "...Improbable extension request for volume..." After digging amongst the RH BZ tickets, I saved the day by : - stopping the VM - lvchange -ay the adequate /dev/... - qemu-img check [-r all] /rhev/blahblah - lvchange -an... - boot the VM - enjoy! Yesterday this worked for a VM where only one error occurred on the qemu image, and the repair was easily done by qemu-img. Today, facing the same issue on another VM, it failed because the errors were very numerous, and also because of this message : [...] Rebuilding refcount structure ERROR writing refblock: No space left on device qemu-img: Check failed: No space left on device [...] The PV/VG/LV are far from being full, so I guess I don't where to look at. I tried many ways to solve it but I'm not comfortable at all with qemu images, corruption and solving, so I ended up exporting this VM (to an NFS export domain), importing it into another DC : this had the side effect to use qemu-img convert from qcow2 to qcow2, and (maybe?????) to solve some errors??? I also copied it into another qcow2 file with the same qemu-img convert way, but it is leading to another clean qcow2 image without errors. I saw that on 4.x some bugs are fixed about VM migrations, but this is not the point here. I checked my SANs, my network layers, my blades, the OS (CentOS 7.2) of my hosts, but I see nothing special. The real reason behind my message is not to know how to repair anything, rather than to understand what could have lead to this situation? Where to keep a keen eye? -- Nicolas ECARNOT
