[Need help] Want to write my graduate thesis related to ovirt
by John Hunter 24 Nov '15

Hi guys, I am college student who is going to graduate next year, major in CS, I want to work on my graduate thesis related to ovirt. For now I need a project which I can work on for the next 6 month, so I need an idealist which I can reference to write a proposal. I have contributed to #dri-devel during my Google Summer of Code project, so I know how opensource groups works, though workflow are kind of different. I am appreciate if anyone could help, and I hope some one could be my mentor.

I went on and unfortunately "net_persistence = ifcfg" in /etc/vdsm/vdsm.conf and restarting VDSM on the host did not solve it (same error as before). While trying (always without success) all other steps suggested by Simone (binding logical network and synchronizing networks from host) I found an interesting-looking libvirt network definition (autostart too) for vdsm-ovirtmgmt and this recalled some memories from past mailing list messages (that I still cannot find...) ;) Long story short: aborting setup, cleaning up all and creating a libvirt network for each pre-provisioned bridge worked! ("net_persistence = ifcfg" has been kept for other, client-specific, reasons so I don't know if it's needed too) Here it is, in BASH form: for my_bridge in ovirtmgmt bridge1 bridge2; do cat <<- EOM > /root/my-${my_bridge}.xml <network> <name>vdsm-${my_bridge}</name> <forward mode='bridge'/> <bridge name='${my_bridge}'/> </network> EOM virsh -c qemu:///system net-define /root/my-${my_bridge}.xml virsh -c qemu:///system net-autostart vdsm-${my_bridge} rm -f /root/my-${my_bridge}.xml done I was able to connect (with the "virsh" commands above) to libvirtd (which must be running for the above to work) by removing the VDSM-added config fragment, allowing tcp connections and denying TLS-only connections in /etc/libvirt/libvirtd.conf and finally by removing /etc/sasl2/libvirt.conf (all these modifications must be reverted after configuring networks then stopping libvirtd and before relaunching setup).

You're welcome to draf a feature page prior to > coding the fix ;-) I was thinking of adding CIFS/NFSv4 functionality to an hyperconverged cluster (GlusterFS/oVirt) which would have separate volumes for virtual machines storage (one volume for the Engine and one for other vms, with no CIFS/NFSv4 capabilities offered) and for data shares (directly accessible by clients on LAN and obviously from local vms too). Think of it as a 3-node HA NetApp+VMware killer ;-) The UI idea (but that would be the Engine part, I understand) was along the lines of single-check enabling CIFS and/or NFSv4 sharing for a GlusterFS data volume, then optionally adding any further specific options (hosts allowed, users/groups for read/write access, network recycle_bin etc.); global Samba (domain/workgroup membership etc.) and CTDB (IPs/interfaces) configuration parameters would be needed too. I have no experience on a GaneshaNFS clustered/HA configuration with GlusterFS, but (from superficial skimming through docs) it seems that it was not possible at all before 2.2 and now it needs a full Pacemaker/Corosync setup too (contrary to the IBM-GPFS-backed case), so that could be a problem. This VDSM wishlist item was driven by the idea that all actions (and so future GlusterFS/Samba/CTDB too) performed by the Engine through the hosts/nodes were somehow "mediated" by VDSM and its API, but if this is not the case, then I retire my suggestion here and I will try to pursue it only on the Engine/Node side ;) Many thanks for your attention.

FOSDEM16 Virt & IaaS Devroom CFP Extension, Speaker Mentoring, CoC
by Mikey Ariel 23 Nov '15

23 Nov '15

The CFP for the Virtualization & IaaS devroom at FOSDEM 2016 is in full swing, and we'd like to share a few updates with you: ------------------------- Speaker Mentoring Program ------------------------- As a part of the rising efforts to grow our communities and encourage a diverse and inclusive conference ecosystem, we're happy to announce that we'll be offering mentoring for newcomer speakers. Our mentors can help you with tasks such as reviewing your abstract, reviewing your presentation outline or slides, or practicing your talk with you. You may apply to the mentoring program as a newcomer speaker if you: * Never presented before or * Presented only lightning talks or * Presented full-length talks at small meetups (<50 ppl) Submission guidelines: * Mentored presentations will have 25-minute slots, where 20 minutes will include the presentation and 5 minutes will be reserved for questions. * The number of newcomer session slots is limited, so we will probably not be able to accept all applications. * You must submit your talk and abstract to apply for the mentoring program, our mentors are volunteering their time and will happily provide feedback but won't write your presentation for you! If you are experiencing problems with Pentabarf, the proposal submission interface, or have other questions, you can email iaas-virt-devroom at lists.fosdem.org and we will try to help you. How to apply: * Follow the same procedure to submit an abstract in Pentabarf as standard sessions. Instructions can be found in our original CFP announcement: http://community.redhat.com/blog/2015/10/call-for-proposals-fosdem16-virtua… * In addition to agreeing to video recording and confirming that you can attend FOSDEM in case your session is accepted, please write "speaker mentoring program application" in the "Submission notes" field, and list any prior speaking experience or other relevant information for your application. Call for mentors! Interested in mentoring newcomer speakers? We'd love to have your help! Please email iaas-virt-devroom at lists.fosdem.org with a short speaker bio and any specific fields of expertise (for example, KVM, OpenStack, storage, etc) so that we can match you with a newcomer speaker from a similar field. Estimated time investment can be as low as a 5-10 hours in total, usually distributed weekly or bi-weekly. Never mentored a newcomer speaker but interested to try? Our mentoring program coordinator will be happy to answer your questions and give you tips on how to optimize the mentoring process. Email us and we'll be happy to answer your questions! ------------------------- CFP Deadline Extension ------------------------- To help accommodate the newcomer speaker proposals, we have decided to extend the deadline for submitting proposals by one week. The new deadline is **TUESDAY, DECEMBER 8 @ midnight CET**. ------------------------- Code of Conduct ------------------------- Following the release of the updated code of conduct for FOSDEM[1], we'd like to remind all speakers and attendees that all of the presentations and discussions in our devroom are held under the guidelines set in the CoC and we expect attendees, speakers, and volunteers to follow the CoC at all times. If you submit a proposal and it is accepted, you will be required to confirm that you accept the FOSDEM CoC. If you have any questions about the CoC or wish to have one of the devroom organizers review your presentation slides or any other content for CoC compliance, please email iaas-virt-devroom at lists.fosdem.org and we will do our best to help you out.

Cannot setup Networks. The address of the network 'NFS' cannot be modified
by Ihor Piddubnyak 23 Nov '15

23 Nov '15

Trying to change IP for VLAN interface attached to hypervisor, getting vhi2: Cannot setup Networks. The address of the network 'NFS' cannot be modified without reinstalling the host, since this address was used to create the host's certification. Host reinstall does not help. Any clue how to do it? -- Ihor Piddubnyak <ip(a)surftown.com> surftown a/s

3.6: GlusterFS data domain failover?
by Wee Sritippho 23 Nov '15

23 Nov '15

------5YHBUFYRT5GVBTR0JVW5A916EMFQ77 Content-Transfer-Encoding: 8bit Content-Type: text/plain; charset=UTF-8 Hi, My POC environment have 2 hosts - host A and host B, both are CentOS7. Installed oVirt 3.6 self-hosted engine. I manually created a 2-brick GlusterFS volume using both hosts and added it to my datacenter. I tried shutting down host A. The hosted-engine restarted in host B within 3 minutes, which is very cool. However, the GlusterFS data domain, which I set both 'Use Host' and 'Path' to the host A, is down along with it. Here comes my questions: 1. How can I enable failover GlusterFS data domain? 2. How can I reverse back to the state before adding the data domain? The data domain is super persistent - I can't edit or delete it. I put it to maintenance mode but still unable to detach or destroy it because it requires me to remove the datacenter first. I tried but can't remove the datacenter either. 3. Why can't I add another GlusterFS data domain? When I choose 'GlusterFS' as my 'Storage Type' every text field become grayed-out. 4. When host A restarted again, I notice that 'Use Host' was changed from host A to host B instead. Is this an expected behavior? Regards, Wee Sritippho P.S: Please excuse my poor English. ------5YHBUFYRT5GVBTR0JVW5A916EMFQ77 Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: 8bit Hi, My POC environment have 2 hosts - host A and host B, both are CentOS7.

report option gone missing
by Rik Theys 23 Nov '15

23 Nov '15

Hi, At some point I had the oVirt reporting configured on my engine and it worked. I had a "reports" option in the menu and could generate reports for various resources. At some point I've noticed that the "reports" option was no longer there but did not have time to investigate. I believe it happened when I migrated the engine host from CentOS 6 to 7 using engine-backup and restore. How can I debug this? In the ovirt-engine-dwh log I used to see the following error: Exception in component tJDBCRollback_4 org.postgresql.util.PSQLException: FATAL: terminating connection due to administrator command at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:2157) at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1886) at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:255) at org.postgresql.jdbc2.AbstractJdbc2Connection.executeTransactionCommand(AbstractJdbc2Connection.java:793) at org.postgresql.jdbc2.AbstractJdbc2Connection.rollback(AbstractJdbc2Connection.java:846) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.tJDBCRollback_4Process(HistoryETL.java:2079) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.tJDBCRollback_3Process(HistoryETL.java:1997) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.tJDBCRollback_2Process(HistoryETL.java:1882) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.tJDBCRollback_1Process(HistoryETL.java:1767) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.tPostjob_1Process(HistoryETL.java:1647) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.runJobInTOS(HistoryETL.java:10785) at ovirt_engine_dwh.historyetl_3_5.HistoryETL.main(HistoryETL.java:10277) 2015-11-19 15:42:02|rza8ri|rza8ri|rza8ri|OVIRT_ENGINE_DWH|HistoryETL|Default|6|Java Exception|tJDBCRollback_4|org.postgresql.util.PSQLException:FATAL: term But after rebooting the engine host it now only lists 'Service Started'. The ovirt-engine-reportsd is also running. Which of these two processes (reportsd vs dwhd) is generating the reports (and showing it in the engine admin interface)?

oVirt 4.0 wishlist: VDSM
by Giuseppe Ragusa 21 Nov '15

21 Nov '15

Hi all, I go on with my wishlist, derived from both solitary mumblings and community talks at the the first Italian oVirt Meetup. I offer to help in coding (work/family schedules permitting) but keep in mind that I'm a sysadmin with mainly C and bash-scripting skills (but hoping to improve my less-than-newbie Python too...) I've sent separate wishlist messages for oVirt Node and Engine. VDSM: *) allow VDSM to configure/manage Samba, CTDB and Ganesha (specifically, I'm thinking of the GlusterFS integration); there are related wishlist items on configuring/managing Samba/CTDB/Ganesha on the Engine and on oVirt Node *) add Open vSwitch direct support (not Neutron-mediated); there are related wishlist items on configuring/managing Open vSwitch on oVirt Node and on the Engine *) add DRBD9 as a supported Storage Domain type; there are related wishlist items on configuring/managing DRBD9 on the Engine and on oVirt Node *) allow VDSM to configure/manage containers (maybe extend it by use of the LXC libvirt driver, similarly to the experimental work that has been put up to allow Xen vm management); there are related wishlist items on configuring/managing containers on the Engine and on oVirt Node *) add a VDSM_remote mode (for lack of a better name, but mainly inspired by pacemaker_remote) to be used inside a guest by the above mentioned container support (giving to the Engine the required visibility on the managed containers, but excluding the "virtual node" from power management and other unsuitable actions) Regards, Giuseppe

ovirt-freeipa authentication howto
by Rob Verduijn 20 Nov '15

20 Nov '15

Hi all, I found that for some reason it is hard to find a working example for integrating ovirt3.5 with freeipa using the generic aaa ldap extension. Here's what I did to get it to work: The ovirt os is centos 6 x86_64 All the latest patches have been applied. the ovirt machinet can be a member of the freeipa domain but this is not required for the ovirt-freeipa authentication to work. personally I think its nice to have the ovirt machine under freeipa supervision as wel. the freeipa os is centos7 x*86_64 All the latest patches have been applied. The ovirt environment is configured, up and running. There are two ways of single sign on for ovirt. see https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualiza… This howto is for the first option you require a search account in the freeipa domain. add a user account to the freeipa domain login with that account so it asks you to set a new password for it then reset the experation date for the password to somewhere in the far future with the procedure below # # Add the search account for ovirt to the freeipa domain. # # executed these commands on the freeipa server as root. # # first set the variables export SUFFIX='dc=example,dc=com' export OVIRT_SERVER=ovirt.example.com export FREEIPA_DOMAIN=EXAMPLE.COM export USERNAME=ovirt export YOUR_PASSWORD='top_secret_random_very_long_password' # create an ldif file cat > resetexperation.ldif << EOF dn: uid=$USERNAME,cn=users,cn=accounts,$SUFFIX changetype: modify replace: krbpasswordexpiration krbpasswordexpiration: 20380119031407Z EOF # apply the ldif file # the password requested is the directory admin password, this is NOT the same account as the freeipa admin ldapmodify -x -D "cn=directory manager" -W -vv -f resetexperation.ldif # for the second option also : # add the service for http to freeipa kinit admin ipa service-add HTTP/$OVIRT_SERVER@$FREEIPA_DOMAIN # # The following commands are executed as root on the ovirt-engine machine. # # # first install the required package : # yum install -y ovirt-engine-extension-aaa-ldap # # ovirt configuration files # examples can be found here : # /usr/share/ovirt-engine-extension-aaa-ldap/examples/simple/. # mkdir /etc/ovirt-engine/aaa mkdir /etc/ovirt-engine/extenstions.d # # set the vars again ( exports do not work between vm's) # export SUFFIX='dc=example,dc=com' export YOUR_PASSWORD='top_secret_random_very_long_password' export FREEIPA_SERVER=freeipa.example.com export PROFILE_NAME=profile1 # # create the config files # cat > /etc/ovirt-engine/aaa/$PROFILE_NAME.properties << EOF include = <ipa.properties> vars.server = $FREEIPA_SERVER vars.user = uid=ovirt,cn=users,cn=accounts,$SUFFIX vars.password = $YOUR_PASSWORD pool.default.serverset.single.server = \${global:vars.server} pool.default.auth.simple.bindDN = \${global:vars.user} pool.default.auth.simple.password = \${global:vars.password} EOF cat > /etc/ovirt-engine/extensions.d/$PROFILE_NAME-authz.properties << EOF ovirt.engine.extension.name = $PROFILE_NAME-authz ovirt.engine.extension.bindings.method = jbossmodule ovirt.engine.extension.binding.jbossmodule.module = org.ovirt.engine-extensions.aaa.ldap ovirt.engine.extension.binding.jbossmodule.class = org.ovirt.engineextensions.aaa.ldap.AuthzExtension ovirt.engine.extension.provides = org.ovirt.engine.api.extensions.aaa.Authz config.profile.file.1 = ../aaa/$PROFILE_NAME.properties EOF cat > /etc/ovirt-engine/extensions.d/$PROFILE_NAME-authn.properties << EOF ovirt.engine.extension.name = $PROFILE_NAME-authn ovirt.engine.extension.bindings.method = jbossmodule ovirt.engine.extension.binding.jbossmodule.module = org.ovirt.engine-extensions.aaa.ldap ovirt.engine.extension.binding.jbossmodule.class = org.ovirt.engineextensions.aaa.ldap.AuthnExtension ovirt.engine.extension.provides = org.ovirt.engine.api.extensions.aaa.Authn ovirt.engine.aaa.authn.profile.name = $PROFILE_NAME ovirt.engine.aaa.authn.authz.plugin = $PROFILE_NAME-authz config.profile.file.1 = ../aaa/$PROFILE_NAME.properties EOF # # change owner and permissions of the profile file # chown ovirt:ovirt /etc/ovirt-engine/extensions.d/$PROFILE_NAME-authn.properties chmod 400 /etc/ovirt-engine/extensions.d/$PROFILE_NAME-authn.properties # # restart the ovirt engine # service ovirt-engine restart # # done you can now add freeipa users to the rhevm portal in the users menu # after the users have been added you can assign permissions for them on the vm's # Cheers Rob Verduijn

Allowing a user to manage all machines in a pool
by Nicolás 20 Nov '15

20 Nov '15

Hi, We're running oVirt 3.5.3.1-1, and we're currently deploying some Pools for students and teachers, so each has access to one machine in the pool. Thus, each of them is granted the UserRole in the pool. Now the teacher is asking us to allow him access to all students' VMs via the Web GUI to evaluate their work. Is there a permission to accomplish that? In worst of cases I will detach the VMs from the pool and grant the teacher the UserRole on each of them, but I'd like to know if there's a "cleaner" way. Thanks. Regards, Nicolás

[EVENTS] oVirt event about storage domain
by Julian De Marchi 20 Nov '15

20 Nov '15

heya-- I am running a 3.6 cluster using hosted-engine. I have finally got the cluster running and left it over the weekend. Today however in my Events panel in the manager interface I am seeing this entry: The Hosted Engine Storage Domain doesn't no exist. It should be imported into the setup. I go to import data into my cluster and it says there is no data domains to import. In 3.5 this was never an issue and the hosted-engine pool was never visible in the management interface. Would appreciate any help. Thanks! --julian

Importing gluster SD from geo-replicated volume
by Ivan Bulatovic 20 Nov '15

20 Nov '15

Hi, I have two DC's (both initialized), two-node each, and on the first one I have a replica 2 gluster storage domain that is geo-replicating on a replica 2 slave volume on the second DC (managed within the same engine). When I stop the replication (volumes are synced) and try to import the gluster storage domain that resides on the slave, import storage domain dialog throws a general exception. Exception is raised when vdsm loads the list of backup servers so that the backup-volfile-servers mount option could get populated. If I override that in storageServer.py, so that it always return blank, or when I manually enter this option in the import storage domain dialog, then everything works as expected. Maybe it's worth mentioning that I have a dedicated gluster network and hostnames for all nodes in both DC's (node hostname, and hostname I use for gluster on that node are different), and that all attempts to import a storage domain were on the second DC. Btw, setting up gluster geo-replication from oVirt was a breeze, easy and straightforward. Importing domain based on slave gluster volume works when gluster storage domain that resides on master volume gets removed from the first DC. This is something that we could improve, if I don't detach and remove original gluster sd, import storage dialog just shows up again after a short "running circle", but it should provide a warning that there is another storage domain already active/registered in the engine with the same ID/name and that the domain should be removed (or the engine can do it for us). I get this warning only when I've already removed storage domain on a master volume from the first DC (which doesn't make sense to me). I can open bug reports for both issues if needed, just want to check if the rationale behind the process is correct or not. vdsm-gluster-4.17.10.1-0.el7 ovirt-engine-webadmin-portal-3.6.1-0.0.master.20151117185807.git529d3d2.el7 engine.log 2015-11-19 07:33:15,245 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-23) [34886be8] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: The error message for connection hostname:/volname returned by VDSM was: General Exception 2015-11-19 07:33:15,245 ERROR [org.ovirt.engine.core.bll.storage.BaseFsStorageHelper] (default task-23) [34886be8] The connection with details 'hostname:/volname' failed because of error code '100' and error message is: general exception vdsm.log Thread-38::ERROR::2015-11-19 07:33:15,237::hsm::2465::Storage.HSM::(connectStorageServer) Could not connect to storageServer Traceback (most recent call last): File "/usr/share/vdsm/storage/hsm.py", line 2462, in connectStorageServer conObj.connect() File "/usr/share/vdsm/storage/storageServer.py", line 224, in connect self._mount.mount(self.options, self._vfsType, cgroup=self.CGROUP) File "/usr/share/vdsm/storage/storageServer.py", line 324, in options backup_servers_option = self._get_backup_servers_option() File "/usr/share/vdsm/storage/storageServer.py", line 341, in _get_backup_servers_option servers.remove(self._volfileserver) ValueError: list.remove(x): x not in list
